1. What Caspofungin Normon is and what it is used for

What Caspofungin Normon is

Caspofungin Normon contains a medicine called caspofungin. It belongs to a group of medicines known as antifungal agents.

What Caspofungin Normon is used for

Caspofungin Normon is used to treat the following infections in children, adolescents, and adults:

• Serious fungal infections in your tissues or organs (called "invasive candidiasis"). This infection is caused by fungal (yeast) cells called Candida.

People who may develop this type of infection include those who have recently undergone surgery or those with weakened immune systems. Fever and chills that do not respond to antibiotic treatment are the most common symptoms of this type of infection.

• Fungal infections in your nose, sinuses, or lungs (called "invasive aspergillosis") when other antifungal treatments have not worked or have caused adverse effects. This infection is caused by molds called Aspergillus.

People who may develop this type of infection include those receiving chemotherapy, those who have undergone organ transplantation, and those with weakened immune systems.

• Presumed fungal infections when you have fever and a low white blood cell count that has not improved with antibiotic treatment. People at risk of developing fungal infections include those who have recently undergone surgery or those with weakened immune systems.

How Caspofungin Normon works

Caspofungin Normon makes fungal cells fragile and prevents the fungus from growing properly. This stops the infection from spreading and allows the body's natural defenses the opportunity to clear the infection completely.

2. What you need to know before starting to use Caspofungin Normon

Do not use Caspofungin Normon

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

If you are unsure, consult your doctor, pharmacist, or nurse before starting to use this medicine.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before starting to use caspofungin if:

• You are allergic to any other medicine.
• You have ever had liver problems; you may require a different dose of this medicine.
• You are already taking cyclosporine (used to prevent organ transplant rejection or to suppress your immune system), as your doctor may need to perform additional blood tests during treatment.
• You have ever had any other medical problems.

If any of the above apply to you (or you are unsure), consult your doctor, pharmacist, or nurse before starting to use caspofungin.

Caspofungin may also cause serious skin adverse reactions, such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN).

Use of Caspofungin Normon with other medicines

Inform your doctor, pharmacist, or nurse if you are taking, have recently taken, or might need to take any other medicines. This includes medicines obtained without a prescription, including herbal medicines. This is because caspofungin may affect how other medicines work. Likewise, other medicines may affect how caspofungin works.

Tell your doctor, pharmacist, or nurse if you are taking any of the following medicines:

• Cyclosporine or tacrolimus (used to prevent organ transplant rejection or to suppress your immune system), as your doctor may need to perform additional blood tests during treatment.
• Certain anti-HIV medicines such as efavirenz or nevirapine.
• Phenytoin or carbamazepine (used to treat seizures).
• Dexamethasone (a steroid).
• Rifampicin (an antibiotic).

If any of the above apply to you (or you are unsure), consult your doctor, pharmacist, or nurse before starting to use caspofungin.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor before using this medicine.

• Caspofungin has not been studied in pregnant women. It should only be used during pregnancy if the potential benefit justifies the possible risks to the developing baby.
• Women receiving caspofungin must not breastfeed.

Driving and using machines

There is no information suggesting that caspofungin affects the ability to drive or operate machinery.

Caspofungin Normon contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per vial; i.e., essentially "sodium-free".

3. How to use Caspofungin Normon

Caspofungin will be given to you:

• Once daily.
• By slow injection into a vein (intravenous infusion).
• Over approximately 1 hour.

Your doctor will determine how long your treatment will last and the amount of caspofungin you will receive each day. Your doctor will monitor whether the medicine's effect is appropriate. If you weigh more than 80 kg, you may require a different dose.

Use in children and adolescents

The dose for children and adolescents may differ from that in adults.

If you use more Caspofungin Normon than you should

Your doctor will decide how much caspofungin you need and for how long each day. If you are concerned that you may have been given too much caspofungin, inform your doctor or nurse immediately.

In case of overdose, consult your doctor or pharmacist or call the Toxicology Information Service at telephone number: 91 562 04 20, indicating the medicine and the amount taken.

If you have any further questions about the use of this medicine, ask your doctor, pharmacist, or nurse.

INSTRUCTIONS FOR USE IN PEDIATRIC PATIENTS

Calculation of Body Surface Area (BSA) for Pediatric Dosing

Prior to preparing the infusion, calculate the patient's body surface area (BSA) using the following formula: (Mosteller formula[1])

Preparation of the 70 mg/m² infusion for pediatric patients >3 months (using a 50 mg vial)

1. Determine the actual loading dose to be used in the pediatric patient using the patient's BSA (as calculated above) and the following equation:

BSA (m²) × 70 mg/m² = loading dose

The maximum loading dose on Day 1 must not exceed 70 mg, regardless of the calculated dose for the patient.

2. Allow the refrigerated Caspofungin Normon vial to reach room temperature.
3. Aseptically add 10.5 ml of Water for Injections. This reconstituted solution may be stored for up to 24 hours at a temperature not exceeding 25 °C.b The final concentration of caspofungin in the vial will be 5.2 mg/ml.
4. Withdraw from the vial a volume of medication equal to the calculated loading dose (Step 1). Aseptically transfer this volume (ml)c of reconstituted Caspofungin Normon to an IV bag (or bottle) containing 250 ml of 0.9% or 0.225% Sodium Chloride Injection, or Lactated Ringer's solution. Alternatively, the volume (ml)c of reconstituted Caspofungin Normon may be added to a reduced volume of 0.9% or 0.225% Sodium Chloride Injection, or Lactated Ringer's solution, provided the final concentration does not exceed 0.5 mg/ml. This infusion solution must be used within 24 hours if stored at a temperature not exceeding 25 °C, or within 48 hours if refrigerated at 2–8 °C.

Preparation of the 50 mg/m² infusion for pediatric patients >3 months (using a 50 mg vial)

1. Determine the actual daily maintenance dose to be used in the pediatric patient using the patient's BSA (as calculated above) and the following equation:

BSA (m²) × 50 mg/m² = daily maintenance dose

The daily maintenance dose must not exceed 70 mg, regardless of the calculated dose for the patient.

2. Allow the refrigerated Caspofungin Normon vial to reach room temperature.
3. Aseptically add 10.5 ml of Water for Injections.a This reconstituted solution may be stored for up to 24 hours at a temperature not exceeding 25 °C.b The final concentration of caspofungin in the vial will be 5.2 mg/ml.
4. Withdraw from the vial a volume of medication equal to the calculated daily maintenance dose (Step 1). Aseptically transfer this volume (ml)c of reconstituted Caspofungin Normon to an IV bag (or bottle) containing 250 ml of 0.9% or 0.225% Sodium Chloride Injection, or Lactated Ringer's solution. Alternatively, the volume (ml)c of reconstituted Caspofungin Normon may be added to a reduced volume of 0.9% or 0.225% Sodium Chloride Injection, or Lactated Ringer's solution, provided the final concentration does not exceed 0.5 mg/ml. This infusion solution must be used within 24 hours if stored at a temperature not exceeding 25 °C, or within 48 hours if refrigerated at 2–8 °C.
