1. What Myalepta is and what it is used for

Myalepta contains the active substance metreleptin. Metreleptin is similar to a human hormone called leptin.
What Myalepta is used for
Myalepta is used to treat complications arising from insufficient levels of leptin in patients with lipodystrophy.
It is used in adults, adolescents, and children from 2 years of age affected by:

  • generalized lipodystrophy (the entire body lacks a sufficient amount of adipose tissue)

It is used, when other therapies have not been effective, in adults and adolescents from 12 years of age affected by:

  • hereditary partial lipodystrophy (also known as congenital or familial lipodystrophy)
  • or acquired partial lipodystrophy (also known as acquired lipodystrophy) caused by the body's response to an event such as a viral illness.

How Myalepta works
Natural leptin is produced by adipose tissue and performs many functions in the body, including:

  • regulating appetite and energy levels;
  • helping the insulin in the body manage blood sugar levels. Metreleptin works by mimicking the effects of leptin. This improves the body’s ability to regulate energy levels.

2. What you should know before using Myalepta

Do not use Myalepta

  • if you are allergic to metreleptin or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions
Talk to your doctor, pharmacist, or nurse before using Myalepta:

  • if you are pregnant
  • if you have had a type of cancer called lymphoma
  • if you have had blood problems (such as low blood cell counts)
  • if you have had inflammation of an organ called the pancreas (pancreatitis)
  • if you have or have had disorders of the immune system (autoimmune diseases, including autoimmune liver problems)

Lymphoma
People with lipodystrophy may develop a type of blood cancer called lymphoma, regardless of whether or not they are using Myalepta.
However, when using this medicine, you may have an increased risk of developing lymphoma.
The decision on whether you should use Myalepta is made by your doctor, who will monitor you during this treatment.

Serious and life-threatening infections
During treatment with Myalepta, your body may produce antibodies that could increase the risk of developing serious and life-threatening infections. Inform your doctor immediately if you develop high fever accompanied by increasing fatigue (see section 4).

Low blood sugar levels with insulin or other antidiabetic medicines
If you are taking a medicine such as insulin or other medicines for the treatment of diabetes, your blood sugar will be closely monitored by your doctor. Your doctor will adjust the dose of insulin or other medicines, if necessary.
This will help prevent your blood sugar from becoming too low ("hypoglycemia"). For signs indicating low blood sugar, see section 4, under "Signs of high and low blood sugar".

High blood sugar levels and high blood fat levels
During treatment with Myalepta, you may have higher levels of sugar (hyperglycemia) or fat (hypertriglyceridemia) in your blood; this may indicate that this medicine is not working as expected. The signs of hyperglycemia and hypertriglyceridemia are listed in section 4, under "Signs of high and low blood sugar" and "Signs of high levels of fats in the blood".
If you notice any of these symptoms described above or in section 4 of this leaflet, or if you have any doubts, contact your doctor immediately. Your treatment may need to be adjusted.

Autoimmune diseases
People who have or have had disorders of the immune system (autoimmune diseases, including autoimmune liver problems) may experience worsening of symptoms with Myalepta. Talk to your doctor about which symptoms to watch for; the appearance of such symptoms should prompt further investigations.

Allergic reactions
During treatment with Myalepta, you may develop an allergic reaction. Inform your doctor immediately if you experience symptoms of an allergic reaction. The signs of an allergic reaction are listed in section 4, under "Allergic reactions".

Fertility
Myalepta may increase fertility in women with lipodystrophy (see section "Pregnancy, breastfeeding and fertility").

Myalepta contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per dose, i.e., essentially 'sodium-free'.

Children and adolescents
Do not give this medicine to children under 2 years of age with generalized lipodystrophy or to children under 12 years of age with partial lipodystrophy. It is not known what effects this medicine may have in children below these age thresholds.

Other medicines and Myalepta
Tell your doctor if you are taking, have recently taken, or might take any other medicines.
Myalepta may affect how other medicines work. In addition, certain medicines may affect how this medicine works.
In particular, inform your doctor if you are taking any of the following medicines:

  • hormonal contraceptives, as Myalepta may reduce their effectiveness in preventing pregnancy
  • theophylline, used for lung diseases such as asthma
  • anticoagulants (such as warfarin or phenprocoumon)
  • medicines that suppress the immune system (such as cyclosporine)
  • antidiabetic medicines (such as insulin or insulin secretagogues), see section 2 'Low blood sugar levels with insulin or other antidiabetic medicines'

If you fall into any of the situations listed above (or have any doubts about them), talk to your doctor before using Myalepta. During treatment with Myalepta, certain medicines may require monitoring, as it may be necessary to adjust their dosage.

Pregnancy, breastfeeding and fertility
If you are pregnant, think you may be pregnant, are planning to become pregnant, or are breastfeeding, consult your doctor or pharmacist before taking this medicine.
Do not use Myalepta if you are pregnant or could become pregnant. It is not known what effects Myalepta may have on the unborn child. Women of childbearing potential must use effective contraceptive methods, including non-hormonal methods such as condoms, during treatment with Myalepta. Discuss appropriate contraceptive methods with your doctor, as Myalepta may reduce the effectiveness of hormonal contraceptives in preventing pregnancy.
It is not known whether Myalepta passes into breast milk. Talk to your doctor if you are breastfeeding or planning to breastfeed. Together with your doctor, you will decide whether to continue or discontinue breastfeeding while being treated with this medicine, taking into account the benefits of breastfeeding for the child and the benefits of Myalepta for the mother.
Myalepta may increase fertility in women with lipodystrophy.

Driving and using machines
Myalepta has a minor influence on the ability to drive and use machines. You may experience dizziness or fatigue while being treated with this medicine. If this occurs, do not drive or operate tools or machinery. If you have any doubts, consult your doctor.

3. How to use Myalepta

Use this medicine exactly as your doctor has told you. If you have any doubts, consult your doctor.

Myalepta is administered by a subcutaneous injection (an injection under the skin) once daily. This medicine is used in children from 2 years of age, adolescents, and adults with generalized lipodystrophy, as well as in children from 12 years of age, adolescents, and adults with partial lipodystrophy.

During treatment with this medicine, your doctor will monitor you or the child and decide which dose should be used.
Your doctor may decide that you can self-inject the medicine. Your doctor, nurse, or pharmacist will show you how to prepare and inject this medicine yourself.

  • Do not try to prepare the medicine or inject it yourself unless you have been trained to do so.

How much medicine to inject

The dose of Myalepta may vary over time, depending on the effects achieved with this medicine. Myalepta powder is dissolved and mixed with water for injections to obtain the solution for injection. Read the “Instructions for use” explaining how to prepare the solution before injection.

Your doctor will prescribe the correct dose based on the following guidelines:

  • If you weigh 40 kg or less:

    • Initial dose of 0.06 mg (0.012 ml of solution) per kilogram of body weight.
  • If you are male and weigh more than 40 kg:

    • Initial dose of 2.5 mg (0.5 ml of solution).
  • If you are female and weigh more than 40 kg:

    • Initial dose of 5 mg (1 ml of solution). Your doctor or pharmacist will inform you of the amount of solution to inject. If you have any doubts about the amount of solution to inject, consult your doctor or pharmacist before proceeding with the injection.
  • The syringe to use for injecting this medicine depends on the dose prescribed to you.
    o Your pharmacist will provide the appropriate syringe for the injection.
    o To determine which syringe to use, refer to the “Instructions for use”.

  • To determine the amount of medicine to inject (in ml), divide the dose (in mg) by 5.
    o For example, if your doctor has prescribed a dose of Myalepta of 5 mg, 5 mg divided by 5 equals 1 ml, which corresponds to the amount of solution to inject using a 1 ml syringe.

  • If the dose is 1.50 mg (0.30 ml of solution) or less, a 0.3 ml syringe must be used.
    o On the 0.3 ml syringe, the amount of solution to inject is indicated in “Units” instead of “ml”. Refer to the “Instructions for use” (section 7) for further information on how to read and use the different syringes.
    o To determine the amount of solution to inject (in Units), divide the dose (in mg) by 5 and then multiply by 100.

If it is necessary to inject 1 ml or more of Myalepta solution, your doctor may instruct you to administer the dose as two separate injections. This may help make the injections more comfortable. For both injections, you must use a clean syringe and needle. If you have any doubts about the amount of solution to inject, consult your doctor or pharmacist before proceeding with the injection.

When small doses/volumes are prescribed (e.g., in children), vials remain almost completely full of product after the required dose has been withdrawn. Any reconstituted solution remaining after use must be discarded.

If you use more Myalepta than you should

If you use more Myalepta than prescribed, inform your doctor immediately or go to the hospital straight away. Your doctor will monitor you for any possible adverse effects.

If you forget to use Myalepta

  • If you forget to inject a dose, inject it as soon as you remember.
  • Then inject your next dose as usual the following day.
  • Do not inject a double dose to make up for the missed dose.

If you have injected less Myalepta than prescribed, inform your doctor immediately. Your doctor will monitor you for any possible adverse effects.

If you stop treatment with Myalepta

Do not stop treatment with Myalepta without first consulting your doctor. Your doctor will decide whether you should discontinue treatment with this medicine.

If it becomes necessary to stop treatment with Myalepta, your doctor will gradually reduce the dose over a period of two weeks before completely stopping therapy. Your doctor will also advise you to follow a low-fat diet.

  • Gradual dose reduction over two weeks is important because it may help prevent a sudden increase in fat levels (called “triglycerides”) in the blood.
  • A sudden increase in triglyceride levels in the blood may cause inflammation of the pancreas (pancreatitis). Gradual dose reduction, together with a low-fat diet, may help prevent this problem.

Do not stop treatment with Myalepta unless your doctor has instructed you to do so.

If you have any questions about how to use this medicine, consult your doctor.

Step A - Preparation

  1. Gather all the materials required for the injection, which have been provided by your doctor, nurse, or pharmacist. Place the following items on a clean, well-lit work surface:
  • one glass vial containing Myalepta powder
  • a container of water for injections, to dissolve the Myalepta powder. The water for injections may be supplied in glass or plastic vials, or in glass vials with a rubber stopper.
  • alcohol swabs (to disinfect the skin where the medicine will be injected and the tops of the vials)
  • sharps container (to safely dispose of used materials after the injection)

Two syringes will also be required:

  • One 1 mL syringe with a 40 mm, 21 gauge needle, to dissolve the powder
  • One injection syringe, equipped with a much shorter needle, to inject the solution subcutaneously. The size of this syringe will be determined by your doctor, nurse, or pharmacist based on your Myalepta dose.
    o If the dose is 1.5 mg or less, the syringe to be used will be 0.3 mL.
    o If the dose is greater than 1.5 mg up to 5 mg, the syringe to be used will be 1 mL.
    o If the dose is greater than 5 mg, the syringe to be used will be 3.0 mL.
    o If the dose is greater than 5 mg, your doctor, nurse, or pharmacist may advise administering the dose as two separate injections. See section 3 “How to use Myalepta” for more information.
Two syringes, two medicine vials, two packets of antiseptic wipes, and a yellow container for disposal of medical waste
  1. Before preparing the Myalepta solution, allow the vial containing the powder to reach room temperature for approximately 10 minutes.
Clear glass vial containing white liquid next to a clock with a 10-minute interval highlighted in blue
  1. Wash your hands before preparing the medicine.
    Step B - Fill the 1 mL syringe with 0.6 mL of water for injections
  2. Remove the 1 mL syringe from its plastic packaging. Always use a new syringe.
  • The 1 mL syringe and needle are supplied separately.
  • How to attach the needle to the syringe depends on the type of water for injections container provided: a plastic vial, a glass vial, or a glass vial with a rubber stopper (see below for specific instructions).
  1. Draw up 0.6 mL of water for injections into the 1 mL syringe.
    The water for injections will be provided by your doctor, nurse, or pharmacist along with the medicine vial and syringes. This water is mixed with the Myalepta powder so that the powder dissolves, turning the medicine into a liquid form suitable for injection. The water for injections may be supplied in one of the following containers:
  • a plastic vial
  • a glass vial
  • a glass vial (with rubber stopper). Always use a new vial or container of water for injections. Never use water for injections left over from preparing the Myalepta solution the previous day.

1. What Myalepta is and what it is used for

  • Myalepta contains the active substance metreleptin. Metreleptin is similar to a human hormone called leptin.

What Myalepta is used for
Myalepta is used to treat complications arising from insufficient levels of leptin in patients with lipodystrophy.
It is used in adults, adolescents, and children from 2 years of age affected by:

  • generalized lipodystrophy (the entire body lacks a sufficient amount of adipose tissue)

It is used, when other therapies have not been effective, in adults and adolescents from 12 years of age affected by:

  • inherited partial lipodystrophy (also called congenital or familial lipodystrophy)
  • or acquired partial lipodystrophy (also called acquired lipodystrophy) caused by the body's response to an event such as a viral illness.

How Myalepta works
Naturally occurring leptin is produced by adipose tissue and performs many functions in the body, including:

  • regulating appetite and energy levels;
  • helping the insulin in the body manage blood sugar levels. Metreleptin works by mimicking the effects of leptin. This improves the body’s ability to regulate energy levels.

2. What you need to know before using Myalepta

Do not use Myalepta

  • if you are allergic to metreleptin or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions
Talk to your doctor, pharmacist, or nurse before using Myalepta:

  • if you are pregnant
  • if you have had a type of cancer called lymphoma
  • if you have had blood problems (such as low blood cell counts)
  • if you have had inflammation of an organ called the pancreas (pancreatitis)
  • if you have or have had disorders of the immune system (autoimmune diseases, including autoimmune liver problems)

Lymphoma
People with lipodystrophy may develop a type of blood cancer called lymphoma, regardless of whether or not they use Myalepta.
However, when using this medicine, you may have an increased risk of developing lymphoma.
The decision on whether you should use Myalepta will be made by your doctor, who will monitor you during treatment.

Serious and life-threatening infections
During treatment with Myalepta, your body may produce antibodies that could increase the risk of developing serious and life-threatening infections. Immediately inform your doctor if you develop high fever accompanied by increasing fatigue (see section 4).

Low blood sugar levels with insulin or other antidiabetic medicines
If you are using a medicine such as insulin or other antidiabetic medicines, your blood sugar will be closely monitored by your doctor. Your doctor will adjust the dose of insulin or other medicines, if necessary.
This will help prevent your blood sugar from becoming too low ("hypoglycemia"). For signs indicating low blood sugar, see section 4, under "Signs of high and low blood sugar".

High blood sugar levels and high blood fat levels
During treatment with Myalepta, you may have higher levels of sugar (hyperglycemia) or fat (hypertriglyceridemia) in your blood; this may indicate that the medicine is not working as expected. Signs of hyperglycemia and hypertriglyceridemia are listed in section 4, under "Signs of high and low blood sugar" and "Signs of high levels of fats in the blood".
If you notice any of these symptoms described above or in section 4 of this leaflet, or if you have any doubts, contact your doctor immediately. Your treatment may need to be adjusted.

Autoimmune diseases
People who have or have had disorders of the immune system (autoimmune diseases, including autoimmune liver problems) may experience worsening of symptoms with Myalepta. Talk to your doctor about which symptoms to watch for; the appearance of such symptoms may require further evaluation.

Allergic reactions
During treatment with Myalepta, you may develop an allergic reaction. Immediately inform your doctor if you experience symptoms of an allergic reaction. Signs of an allergic reaction are described in section 4, under "Allergic reactions".

Fertility
Myalepta may increase fertility in women with lipodystrophy (see section "Pregnancy, breastfeeding and fertility").

Myalepta contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per dose, i.e., essentially 'sodium-free'.

Children and adolescents
Do not give this medicine to children under 2 years of age with generalized lipodystrophy or to children under 12 years of age with partial lipodystrophy. The effects of this medicine in children below these age thresholds are not known.

Other medicines and Myalepta
Tell your doctor if you are taking, have recently taken, or might take any other medicines.
Myalepta may affect how other medicines work. Also, some medicines may affect how this medicine works.
In particular, inform your doctor if you are taking any of the following medicines:

  • hormonal contraceptives, because Myalepta may reduce their effectiveness in preventing pregnancy
  • theophylline, used for lung diseases such as asthma
  • anticoagulants (such as warfarin or phenprocoumon)
  • medicines that suppress the immune system (such as cyclosporine)
  • antidiabetic medicines (such as insulin or insulin secretagogues); see section 2, 'Low blood sugar levels with insulin or other antidiabetic medicines'

If you are in any of the situations listed above (or have any doubts about this), talk to your doctor before using Myalepta. During treatment with Myalepta, some medicines need to be monitored, as dose adjustments may be necessary.

Pregnancy, breastfeeding and fertility
If you are pregnant, think you may be pregnant, planning to become pregnant, or breastfeeding, ask your doctor or pharmacist for advice before taking this medicine.
Do not use Myalepta if you are pregnant or could become pregnant. The effects of Myalepta on the unborn child are not known. Women who can become pregnant must use effective contraceptive methods, including non-hormonal methods such as condoms, during treatment with Myalepta. Discuss appropriate contraceptive methods with your doctor, as Myalepta may reduce the effectiveness of hormonal contraceptives in preventing pregnancy.
It is not known whether Myalepta passes into breast milk. Talk to your doctor if you are breastfeeding or planning to breastfeed. Together with your doctor, you will decide whether to continue or stop breastfeeding while being treated with this medicine, taking into account the benefits of breastfeeding for the child and the benefits of Myalepta for the mother.
Myalepta may increase fertility in women with lipodystrophy.

Driving and using machines
Myalepta has a minor influence on the ability to drive and use machines. You may experience dizziness or fatigue while being treated with this medicine. If this occurs, do not drive or operate tools or machinery. If you have any doubts, consult your doctor.

3. How to use Myalepta

Use this medicine exactly as your doctor has told you. If you have any doubts, consult your doctor.

Myalepta is administered by a subcutaneous injection (an injection under the skin) once daily. This medicine is used in children from 2 years of age, adolescents, and adults with generalized lipodystrophy, as well as in children from 12 years of age, adolescents, and adults with partial lipodystrophy.

During treatment with this medicine, your doctor will monitor you or your child and decide which dose should be used.

Your doctor may decide that you can self-inject the medicine. Your doctor, nurse, or pharmacist will show you how to prepare and inject this medicine yourself.

  • Do not try to prepare the medicine or inject it yourself unless you have been trained to do so.

How much medicine to inject

The dose of Myalepta may vary over time depending on the effects achieved with this medicine. The Myalepta powder is dissolved and mixed with water for injections to obtain the solution for injection. Read the “Instructions for Use” that explain how to prepare the solution before injection.

Your doctor will prescribe the correct dose based on the following guidelines:

  • If you weigh 40 kg or less:

    • Initial dose of 0.06 mg (0.012 mL of solution) per kilogram of body weight.
  • If you are male and weigh more than 40 kg:

    • Initial dose of 2.5 mg (0.5 mL of solution).
  • If you are female and weigh more than 40 kg:

    • Initial dose of 5 mg (1 mL of solution). Your doctor or pharmacist will inform you of the amount of solution to inject. If you have any doubts about the amount of solution to inject, consult your doctor or pharmacist before proceeding with the injection.
  • The syringe to use for injecting this medicine depends on the dose prescribed to you.

    • Your pharmacist will provide you with the appropriate syringe for the injection.
    • To determine which syringe to use, refer to the “Instructions for Use”.
  • To determine the amount of medicine to inject (in mL), divide the dose (in mg) by 5.

    • For example, if your doctor has prescribed a dose of Myalepta of 5 mg, 5 mg divided by 5 equals 1 mL, which corresponds to the amount of solution to inject using a 1 mL syringe.
  • If the dose is 1.50 mg (0.30 mL of solution) or less, a 0.3 mL syringe must be used.

    • On the 0.3 mL syringe, the amount of solution to inject is indicated in “Units” instead of “mL”. Refer to the “Instructions for Use” (section 7) for further information on how to read and use the different syringes.
    • To determine the amount of solution to inject (in Units), divide the dose (in mg) by 5 and then multiply by 100.

If it is necessary to inject 1 mL or more of the Myalepta solution, your doctor may instruct you to administer the dose as two separate injections. This may help make the injections more comfortable. For both injections, you must use a clean syringe and needle. If you have any doubts about the amount of solution to inject, consult your doctor or pharmacist before proceeding with the injection.

When small doses/volumes are prescribed (e.g., in children), the vials remain almost completely full after the required dose has been withdrawn. Any reconstituted solution remaining after use must be discarded.

If you use more Myalepta than you should

If you use more Myalepta than you should, inform your doctor immediately or go to hospital straight away. Your doctor will monitor you for any possible side effects.

If you forget to use Myalepta

  • If you forget to inject a dose, inject it as soon as you remember.
  • Then inject your next dose as usual the following day.
  • Do not use a double dose to make up for the forgotten dose.

If you have injected less Myalepta than you should have, inform your doctor immediately. Your doctor will monitor you for any possible side effects.

If you stop using Myalepta

Do not stop treatment with Myalepta without first consulting your doctor. Your doctor will decide whether you should stop treatment with this medicine.

If it becomes necessary to stop treatment with Myalepta, your doctor will gradually reduce the dose over a period of two weeks before stopping the treatment completely. Your doctor will also advise you to follow a low-fat diet.

  • Gradual dose reduction over two weeks is important because it may help prevent a sudden increase in fat levels (called “triglycerides”) in the blood.
  • A sudden increase in triglyceride levels in the blood may cause inflammation of the pancreas (pancreatitis). Gradual dose reduction, together with a low-fat diet, may help prevent this problem.

Do not stop treatment with Myalepta unless your doctor has told you to do so.

If you have any doubts about how to use this medicine, consult your doctor.

Step A - Preparation

  1. Gather all materials needed for the injection, as provided by your doctor, nurse, or pharmacist.
    Place the following items on a clean, well-lit work surface:
  • one glass vial containing Myalepta powder
  • a container of water for injections, to dissolve the Myalepta powder – the water for injections may be supplied in glass or plastic vials, or in glass vials with a rubber stopper
  • alcohol swabs (to disinfect the skin at the injection site and the tops of the vials)
  • sharps disposal container (for safe disposal of used materials after the injection)

Two syringes will also be required:

  • A 3 mL syringe with a 40 mm, 21 gauge needle, to dissolve the powder
  • An injection syringe with a much shorter needle, to inject the solution subcutaneously. The size of this syringe will be determined by your doctor, nurse, or pharmacist based on your Myalepta dose.
    o If the dose is 1.5 mg or less, the syringe to be used is 0.3 mL.
    o If the dose is greater than 1.5 mg up to 5 mg, the syringe to be used is 1 mL.
    o If the dose is greater than 5 mg, the syringe to be used is 3.0 mL.
    o If the dose is greater than 5 mg, your doctor, nurse, or pharmacist may advise administering the dose via two separate injections. See section 3 “How to use Myalepta” for further information.

1. What Myalepta is and what it is used for

Myalepta contains the active substance metreleptin. Metreleptin is similar to a human hormone called leptin.
What Myalepta is used for
Myalepta is used to treat complications arising from insufficient levels of leptin in patients with lipodystrophy.
It is used in adults, adolescents, and children from 2 years of age affected by:

  • generalized lipodystrophy (the entire body lacks a sufficient amount of adipose tissue)

It is used, when other therapies have not been effective, in adults and adolescents from 12 years of age affected by:

  • inherited partial lipodystrophy (also known as congenital or familial lipodystrophy)
  • or acquired partial lipodystrophy (also known as acquired lipodystrophy) caused by the body's response to an event such as a viral illness.

How Myalepta works
Natural leptin is produced by adipose tissue and performs many functions in the body, including:

  • regulating appetite and energy levels;
  • helping the body's insulin manage blood sugar levels. Metreleptin works by mimicking the effects of leptin. This improves the body's ability to regulate energy levels.

2. What you should know before using Myalepta

Do not use Myalepta

  • if you are allergic to metreleptin or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions
Talk to your doctor, pharmacist, or nurse before using Myalepta:

  • if you are pregnant
  • if you have previously suffered from a type of cancer called lymphoma
  • if you have had blood problems (such as a low number of blood cells)
  • if you have had inflammation of an organ called the pancreas (pancreatitis)
  • if you currently suffer or have previously suffered from disorders of the immune system (autoimmune diseases, including autoimmune liver problems)

Lymphoma
People with lipodystrophy may develop a type of blood cancer called lymphoma, regardless of whether or not they use Myalepta.
However, when using this medicine, you may have an increased risk of developing lymphoma.
The decision on whether you should use Myalepta will be made by your doctor, who will monitor you during treatment.

Serious and life-threatening infections
During treatment with Myalepta, your body may produce antibodies that could increase the risk of developing serious and life-threatening infections. Immediately inform your doctor if you develop high fever accompanied by increasing fatigue (see section 4).

Low blood sugar levels with insulin or other antidiabetic medicines
If you are using a medicine such as insulin or other antidiabetic medicines, your blood sugar level will be closely monitored by your doctor. The doctor will adjust the dose of insulin or other medicines as necessary.
This will help prevent your blood sugar from becoming too low ("hypoglycemia"). For signs indicating low blood sugar, see section 4, under "Signs of high and low blood sugar".

High blood sugar levels and high blood fat levels
During treatment with Myalepta, you may experience elevated blood sugar (hyperglycemia) or elevated blood fats (hypertriglyceridemia); this may indicate that this medicine is not working as expected. Signs of hyperglycemia and hypertriglyceridemia are listed in section 4, under "Signs of high and low blood sugar" and "Signs of high levels of fats in the blood".
If you notice any of these symptoms described above or in section 4 of this leaflet, or if you have any doubts, contact your doctor immediately. Your treatment may need to be adjusted.

Autoimmune diseases
People who currently suffer or have previously suffered from disorders of the immune system (autoimmune diseases, including autoimmune liver problems) may experience worsening of symptoms with Myalepta. Talk to your doctor about which symptoms to watch for; the appearance of such symptoms may require further evaluation.

Allergic reactions
During treatment with Myalepta, you may develop an allergic reaction. Immediately inform your doctor if you experience symptoms of an allergic reaction. Signs of an allergic reaction are listed in section 4, under "Allergic reactions".

Fertility
Myalepta may increase fertility in women with lipodystrophy (see section "Pregnancy, breastfeeding and fertility").

Myalepta contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per dose, i.e., essentially 'sodium-free'.

Children and adolescents
Do not give this medicine to children under 2 years of age with generalized lipodystrophy or to children under 12 years of age with partial lipodystrophy. It is not known what the effects of this medicine are in children below these age thresholds.

Other medicines and Myalepta
Tell your doctor if you are taking, have recently taken, or might take any other medicines.
Myalepta may affect how other medicines work. In addition, certain medicines may affect how this medicine works.
In particular, inform your doctor if you are taking any of the following medicines:

  • hormonal contraceptives, as Myalepta may reduce their effectiveness in preventing pregnancy
  • theophylline, used for lung diseases such as asthma
  • anticoagulants (such as warfarin or phenprocoumon)
  • medicines that suppress the immune system (such as cyclosporine)
  • antidiabetic medicines (such as insulin or insulin secretagogues), see section 2 'Low blood sugar levels with insulin or other antidiabetic medicines'

If you fall into any of the situations listed above (or have any doubts), talk to your doctor before using Myalepta. During treatment with Myalepta, some medicines need to be monitored, as it may be necessary to adjust their dosage.

Pregnancy, breastfeeding and fertility
If you are pregnant, think you might be pregnant, are planning to become pregnant, or are breastfeeding, consult your doctor or pharmacist before taking this medicine.
Do not use Myalepta if you are pregnant or could become pregnant. It is not known what effects Myalepta may have on the unborn child. Women of childbearing potential must use effective contraceptive methods, including non-hormonal methods such as condoms, during treatment with Myalepta. Discuss appropriate contraceptive methods with your doctor, as Myalepta may reduce the effectiveness of hormonal contraceptives in preventing pregnancy.
It is not known whether Myalepta passes into breast milk. Talk to your doctor if you are breastfeeding or intend to breastfeed. Together with your doctor, you will decide whether to continue or discontinue breastfeeding while being treated with this medicine, taking into account the benefits of breastfeeding for the child and the benefits of Myalepta for the mother.
Myalepta may increase fertility in women with lipodystrophy.

Driving and using machines
Myalepta has a minor influence on the ability to drive vehicles and use machines. You may experience dizziness or fatigue while being treated with this medicine. If this occurs, do not drive or operate tools or machinery. If you have any doubts, consult your doctor.

3. How to use Myalepta

Use this medicine exactly as your doctor has told you. If you have any doubts, consult your doctor.

Myalepta is administered by a subcutaneous injection (an injection under the skin) once daily. This medicine is used in children from 2 years of age, adolescents, and adults with generalized lipodystrophy, as well as in children from 12 years of age, adolescents, and adults with partial lipodystrophy.

During treatment with this medicine, your doctor will monitor you or your child and decide which dose should be used.

Your doctor may decide that you can self-inject the medicine. Your doctor, nurse, or pharmacist will show you how to prepare and inject this medicine yourself.

  • Do not try to prepare the medicine or inject it yourself unless you have been trained to do so.

How much medicine to inject

The dose of Myalepta may vary over time, depending on the effects achieved with this medicine. The Myalepta powder is dissolved and mixed with water for injections to prepare the solution for injection. Read the "Instructions for use" that explain how to prepare the solution before injection.

Your doctor will prescribe the correct dose based on the following:

  • If you weigh 40 kg or less:

    • Initial dose of 0.06 mg (0.012 mL of solution) per kilogram of body weight.
  • If you are male and weigh more than 40 kg:

    • Initial dose of 2.5 mg (0.5 mL of solution).
  • If you are female and weigh more than 40 kg:

    • Initial dose of 5 mg (1 mL of solution). Your doctor or pharmacist will inform you of the volume of solution to inject. If you have any doubts about the volume of solution to inject, consult your doctor or pharmacist before proceeding with the injection.
  • The syringe to use for injecting this medicine depends on the dose prescribed to you.

    • Your pharmacist will provide you with the appropriate syringe for the injection.
    • To find out which syringe to use, refer to the "Instructions for use".
  • To determine the volume of medicine to inject (in mL), divide the dose (in mg) by 5.

    • For example, if your doctor has prescribed a dose of Myalepta of 5 mg, 5 mg divided by 5 equals 1 mL, which corresponds to the volume of solution to be injected using a 1 mL syringe.
  • If the dose is 1.50 mg (0.30 mL of solution) or less, a 0.3 mL syringe must be used.

    • On the 0.3 mL syringe, the volume of solution to inject is indicated in "Units" instead of "mL". Refer to the "Instructions for use" (section 7) for further information on how to read and use the different syringes.
    • To determine the volume of solution to inject (in Units), divide the dose (in mg) by 5 and then multiply by 100.

If it is necessary to inject 1 mL or more of Myalepta solution, your doctor may instruct you to administer the dose in two separate injections. This may help make the injections more comfortable. For both injections, you must use a clean syringe and needle.

If you have any doubts about the volume of solution to inject, consult your doctor or pharmacist before proceeding with the injection.

When small doses/volumes are prescribed (e.g., in children), the vials will remain almost completely full after the required dose has been withdrawn. Any reconstituted solution remaining must be discarded after use.

If you use more Myalepta than you should

If you use more Myalepta than you should, inform your doctor immediately or go to hospital straight away. Your doctor will monitor you for any possible adverse effects.

If you forget to use Myalepta

  • If you forget to inject a dose, inject it as soon as you remember.
  • Then inject your next dose as usual the following day.
  • Do not inject a double dose to make up for the missed dose.

If you have injected less Myalepta than you should have, inform your doctor immediately. Your doctor will monitor you for any possible adverse effects.

If you stop using Myalepta

Do not stop treatment with Myalepta without first consulting your doctor. Your doctor will decide whether you should stop treatment with this medicine.

If it is necessary to stop treatment with Myalepta, your doctor will gradually reduce the dose over a period of two weeks before stopping the treatment completely. Your doctor will also advise you to follow a low-fat diet.

  • Gradually reducing the dose over a two-week period is important because it may help prevent a sudden increase in fat levels (called "triglycerides") in the blood.
  • A sudden increase in triglyceride levels in the blood may cause inflammation of the pancreas (pancreatitis). Gradual dose reduction, together with a low-fat diet, may help prevent this problem.

Do not stop treatment with Myalepta unless your doctor has instructed you to do so.

If you have any doubts about how to use this medicine, consult your doctor.

Step A – Preparation

  1. Gather all materials required for the injection, as provided by your doctor, nurse, or pharmacist.
    Place the following items on a clean, well-lit work surface:
  • one glass vial containing Myalepta powder
  • a container of water for injections, to dissolve the Myalepta powder. The water for injections may be supplied in glass or plastic vials, or in glass vials with a rubber stopper.
  • alcohol swabs (to disinfect the skin at the injection site and the top of the vials)
  • sharps container (to safely dispose of used materials after the injection)

Two syringes will also be required:

  • One 3 mL syringe with a 40 mm, 21 gauge needle, to dissolve the powder
  • One injection syringe with a much shorter needle, to inject the solution subcutaneously. The size of this syringe will be determined by your doctor, nurse, or pharmacist based on your Myalepta dose.
    o If the dose is 1.5 mg or less, a 0.3 mL syringe will be used.
    o If the dose is greater than 1.5 mg up to 5 mg, a 1 mL syringe will be used.
    o If the dose is greater than 5 mg, a 3.0 mL syringe will be used.
    o If the dose is greater than 5 mg, your doctor, nurse, or pharmacist may advise administering the dose as two separate injections. See section 3 “How to use Myalepta” for further information.

Step E – Choosing and preparing the injection site
22) Carefully select the site where you intend to inject Myalepta. This medicine may be injected in the following areas:

  • abdominal area (excluding a 5 cm zone around the navel)
  • thighs
  • upper back area of the arm
Diagram of a human body viewed from front and back with orange areas marked on abdomen, thighs, and upper arms

If you plan to use the same body area for each injection, avoid the site used for the previous injection.

  • If you are injecting other medicines, do not inject Myalepta at the same site as other injections.
  1. Clean the selected injection site with a clean alcohol swab and allow the skin to dry.
  • Avoid touching the cleaned area before administering the Myalepta injection.

Step F – Injecting Myalepta
Important: Myalepta must be injected under the skin (“subcutaneous use”). Do not inject the medicine into a muscle.
24) To perform a subcutaneous injection, pinch the skin at the injection site with one hand.
