1. What Bertanel is and what it is used for

Bertanel is a medicine containing methotrexate. Methotrexate is a substance that has the following properties:

• interferes with the growth of certain cells in the body that multiply rapidly (antitumour agent)
• reduces unwanted reactions of the body's own defence mechanisms (immunosuppressant)

and

• has anti-inflammatory effects.

Bertanel is used in patients with:

• active rheumatoid arthritis (RA) in adults
• polyarticular forms (when five or more joints are involved) of active and severe juvenile idiopathic arthritis (children over 3 years of age) (JIA) when the response to non-steroidal anti-inflammatory drugs (NSAIDs) has been inadequate
• severe, disabling, recalcitrant psoriasis that does not respond adequately to other forms of treatment such as phototherapy, PUVA, and retinoids, and severe psoriasis affecting the joints (psoriatic arthritis) in adult patients.

2. What you need to know before using Bertanel

Ask your doctor or pharmacist if you have any questions before using Bertanel.

Do not use Bertanel

• if you are allergic (hypersensitive) to methotrexate or any of the other components of this medicine (listed in section 6)
• if you have an existing or serious infection
• if you have inflammation of the mouth or active peptic ulcers
• if you have significant kidney disease (your doctor determines the severity of the disease)
• if you have significant liver disease (your doctor determines the severity of your condition)
• if you have disorders of the blood-forming system (your doctor determines the severity of your condition)
• if you have increased alcohol consumption (if you have alcohol-induced liver disease or another chronic liver disease)
• if your immune system is impaired (e.g., AIDS)
• if you are pregnant or breastfeeding (see section “Pregnancy, breastfeeding and fertility”).

Warnings and precautions

Important warning regarding methotrexate dosing:

Methotrexate for the treatment of rheumatic or skin diseases must only be used once per week.

Always use Bertanel exactly as your doctor has instructed.

Incorrect dosing of methotrexate may cause serious adverse effects, including fatal outcomes. Please read section 3 of this leaflet carefully.

Talk to your doctor before using Bertanel.

Especially in elderly patients, deaths have been reported following the accidental daily use of the weekly dose.

Methotrexate should only be prescribed by physicians with sufficient experience in treating the condition with methotrexate.

Your doctor will inform you about the potential benefits and risks (including early signs and symptoms of toxicity) of methotrexate therapy.

You need to be closely monitored during therapy so that signs of possible toxic effects or adverse reactions can be detected as early as possible.

If you notice symptoms of intoxication (please refer to section 4 "Possible side effects"), contact your doctor immediately. Your doctor will decide whether monitoring and treatment of intoxication symptoms are necessary and will inform you of additional measures.

Consult your doctor or pharmacist before using Bertanel if you:

• have insulin-treated diabetes mellitus
• have inactive chronic infections (e.g., tuberculosis, hepatitis B or C, herpes (herpes zoster)), as these conditions could reactivate
• have or have had liver or kidney disease
• have or have had problems with lung function
• are obese
• have abnormal fluid accumulation in the abdomen or in the cavity between the lungs and the chest wall (ascites, pleural effusion)

Liver function

Methotrexate may damage the liver; during treatment with Bertanel, you must avoid drinking alcohol and taking other medications that may harm the liver. Before and during treatment with Bertanel, your doctor must perform blood tests to monitor liver function. Please also refer to the sections "Other medicines and Bertanel" and “Bertanel with food and alcohol” and section 4.

Kidney function

Bertanel may damage the kidneys. Your doctor must perform blood tests before and during treatment to monitor your kidney function. If you are dehydrated or have a condition that may cause dehydration (vomiting, diarrhea, stomatitis), methotrexate toxicity may increase. Your doctor may suspend Bertanel therapy. Please also refer to section 4.

Blood-forming system and immune system

Treatment with Bertanel could damage your bone marrow (bone marrow suppression). This may lead to serious infections and/or bleeding and anemia.

Your doctor will perform blood tests so these conditions can be treated as early as possible.

Contact your doctor if you experience fever, sore throat, mouth ulcers, flu-like symptoms, exhaustion, bruising, or bleeding.

Methotrexate may affect the effectiveness of vaccines or immune response tests due to its effect on the immune system.

Nervous system

Certain brain disorders (encephalitis/encephalopathy), which could be fatal, have been reported with intravenous methotrexate. Cases of leukoencephalopathy have been reported in patients treated with oral methotrexate. If you, your partner, or caregiver notice the onset or worsening of neurological symptoms such as general muscle weakness, vision disturbances, changes in thinking, memory, and orientation leading to confusion and personality changes, contact your doctor immediately, as these may be symptoms of a rare but serious brain infection called progressive multifocal leukoencephalopathy (PML).

Skin

Methotrexate may make your skin sensitive to sunlight, so you should avoid prolonged sun exposure.

You should not visit a tanning salon without first consulting your doctor.

Methotrexate may increase the skin's sensitivity to sunlight. Avoid intense sunlight and do not use sunbeds or ultraviolet lamps without medical advice. To protect your skin from intense sunlight, wear appropriate clothing or use a high-protection sunscreen.

Skin changes caused by psoriasis may worsen during treatment with Bertanel if exposure to UV radiation occurs simultaneously.

If you have previously experienced skin problems after radiotherapy (radiation-induced dermatitis) or sunburn, these conditions may reappear under methotrexate therapy (memory effect).

Serious, sometimes fatal, skin reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis (Lyell’s syndrome) have been reported after single or continuous use of methotrexate (please refer to section 4).

Gastrointestinal system

Treatment with methotrexate may lead to serious complications in your gastrointestinal system. In such cases, methotrexate treatment must be discontinued.

Contact your doctor immediately if you experience any gastrointestinal problems (please refer to section 4).

Infections

Treatment with methotrexate may lead to infections, which may be fatal in some cases.

Contact your doctor immediately if you experience signs of infection (please refer to section 4).

Lung function

Treatment with methotrexate may lead to serious pulmonary complications. In such cases, methotrexate treatment must be discontinued.

Contact your doctor immediately if you experience any breathing problems or lung issues (please refer to section 4).

Acute lung hemorrhage has been reported with methotrexate in patients with underlying rheumatic disease. If you experience symptoms of coughing up or spitting blood, contact your doctor immediately.

Tumors

A rare cancer of the lymph nodes (malignant lymphoma) may occur in patients receiving low-dose methotrexate, which in some cases resolved after discontinuation of treatment; therefore, cytotoxic treatment may not be required. If lymphoma develops, methotrexate therapy must be discontinued; and only if the lymphoma does not resolve should appropriate cytostatic treatment be initiated.

Methotrexate temporarily affects the production of sperm and ova, which is reversible in most cases.

Methotrexate may cause miscarriages and severe congenital defects. If you are a woman, you must avoid becoming pregnant while using methotrexate and for at least six months after stopping treatment. If you are a man, you must avoid fathering a child while receiving methotrexate and for at least 3 months after completing treatment. See also the section “Pregnancy, breastfeeding and fertility”.

Follow-up examinations and recommended precautions:

Although Bertanel is administered at low doses, serious adverse effects may occur. To detect them as early as possible, your doctor must perform follow-up examinations and laboratory tests.

Before starting treatment:

Before starting treatment, you will have a blood test to check whether you have sufficient blood cells. Your liver function and whether you have hepatitis will also be checked. Additionally, serum albumin (a blood protein), hepatitis status (liver infection), and kidney function will be assessed. Your doctor may decide to perform additional liver tests, some of which may include imaging of your liver, and others may require a small tissue sample from your liver for closer examination. Your doctor may also check whether you have tuberculosis and may order a chest X-ray or a lung function test.

During treatment:

Your doctor may perform the following tests:

• examination of the oral cavity and pharynx to detect changes in the mucous membrane, such as inflammation or ulcers
• blood tests/blood counts, including blood cell count and measurement of serum methotrexate levels
• blood tests to monitor liver function
• imaging tests to monitor liver function
• taking a small tissue sample from the liver for closer examination
• blood tests to monitor kidney function
• monitoring of the respiratory tract and, if necessary, lung function tests

It is very important that you attend these scheduled tests.

If the results of any of these tests are abnormal, your doctor will adjust your treatment accordingly.

Do not miss any of your scheduled tests.

If the results of any of these tests are not normal, your doctor will take appropriate measures.

Elderly patients

Elderly patients receiving methotrexate must be under close medical supervision so that possible adverse effects can be detected as early as possible. Age-related decline in liver and kidney function, as well as low folic acid reserves in older age, require administration of a relatively low dose of methotrexate.

Children and adolescents

Use is not recommended in children under 3 years of age due to lack of experience in this age group.

Children treated with methotrexate must be under particularly close medical supervision by specialists in this field to identify possible side effects as early as possible.

Other medicines and Bertanel

Inform your doctor or pharmacist if you are using, have recently used, or might need to use any other medicines, including over-the-counter medicines such as herbal remedies or vitamins.

It is especially important that you inform your doctor if you are taking:

• medicines that may damage the liver such as:

• azathioprine (used to prevent organ transplant rejection)

• leflunomide (for rheumatoid arthritis)

• retinoids (used to treat psoriasis and other skin disorders)

• sulfasalazine (used for rheumatoid arthritis and ulcerative colitis)

• other treatments for rheumatoid arthritis or psoriasis, such as gold, penicillamine, hydroxychloroquine, sulfasalazine, azathioprine, and cyclosporine (to suppress the immune system)

• medicines for pain and/or inflammation (non-steroidal anti-inflammatory drugs or salicylates, such as ibuprofen, indomethacin, phenylbutazone, amidopyrine derivatives and acetylsalicylic acid derivatives, including salicylic acid). This also applies to medicines available without a prescription

• some cancer treatments (cytotoxic agents such as doxorubicin, mercaptopurine, procarbazine, cisplatin, L-asparaginase, vincristine, cytarabine, and 5-fluorouracil)

• antibiotics (e.g., penicillin, sulfonamides, trimethoprim/sulfamethoxazole, tetracyclines, ciprofloxacin, pristinamycin, chloramphenicol)

• metamizole (synonyms: novaminsulfone and dipyrone) (a medicine for severe pain and/or fever)

• penicillins may reduce methotrexate excretion, potentially increasing adverse effects

• tranquilizers (e.g., benzodiazepines such as lorazepam, alprazolam)

• medicines for high blood sugar levels (tolbutamide, glipizide, glimepiride)

• para-aminobenzoic acid (treatment for skin problems)

• oral contraceptives

• triamterene (treatment for high blood pressure)

• anticonvulsant medicines, such as phenytoin, levetiracetam (prevent seizures) and barbiturates (also used as sleeping injections)

• probenecid (for gout)

• hippuric acid (a substance used to assess kidney function)

• pyrimethamine (used to prevent and treat malaria)

• medicines used to treat severe stomach acidity or ulcers (e.g., proton pump inhibitors such as omeprazole, pantoprazole, lansoprazole)

• theophylline (used to treat asthma and other lung diseases)

• amiodarone (to treat heart rhythm disorders)

• nitrous oxide-based anesthesia (talk to your doctor if you have surgery planned)

• vitamin preparations containing folic acid, folinic acid, or any derivative

You must not receive live vaccinations simultaneously with methotrexate treatment. If you are unsure, consult your doctor.

Development of skin cancer has been reported in some psoriasis patients receiving methotrexate and PUVA therapy (ultraviolet light treatment).

Radiation therapy during methotrexate treatment may increase the risk of necrosis (damaged tissue due to cell death) in soft or bone tissue.

Bertanel with food and alcohol

During treatment with Bertanel, alcohol consumption must be avoided, as it may increase toxicity (especially hepatotoxicity). You should also avoid excessive consumption of coffee, caffeine-containing beverages, and black tea.

Pregnancy, breastfeeding and fertility

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

Pregnancy

Do not use Bertanel during pregnancy or if you are trying to become pregnant. Methotrexate may cause birth defects, harm the fetus, or lead to miscarriage. It is associated with malformations of the skull, face, heart and blood vessels, brain, and limbs. Therefore, it is very important that methotrexate is not administered to pregnant patients or those planning to become pregnant. In women of childbearing potential, pregnancy must be ruled out by appropriate measures, for example, a pregnancy test before starting treatment. You must avoid becoming pregnant while taking methotrexate and for at least 6 months after stopping treatment, using reliable contraceptive methods throughout this period (see also section “Warnings and precautions”).

If you become pregnant during treatment or suspect you may be pregnant, consult your doctor as soon as possible. You should be provided with information about the risk of harmful effects on the child during treatment.

If you wish to become pregnant, consult your doctor, who may refer you to a specialist for counseling before the planned start of treatment.

Breastfeeding

You must not breastfeed during treatment, as methotrexate passes into breast milk. If your doctor considers methotrexate treatment absolutely necessary, breastfeeding must be discontinued.

Male fertility

Available data do not indicate an increased risk of malformations or miscarriages if the father takes a methotrexate dose below 30 mg/week. However, this risk cannot be completely ruled out. Methotrexate may be genotoxic, meaning it may cause genetic mutations. Methotrexate may affect sperm production and cause birth defects. Therefore, you must avoid fathering a child or donating semen while taking methotrexate and for at least 3 months after stopping treatment.

Driving and using machines

During treatment with Bertanel, adverse effects affecting the central nervous system such as fatigue, drowsiness, and dizziness may occur. Therefore, in some cases, your ability to drive vehicles and/or operate machinery may be impaired. If you feel tired or dizzy, do not drive or operate tools or machinery. This is particularly important if taken with alcohol.

Bertanel contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per weekly dose; hence, it is essentially “sodium-free”.

3. How to use Bertanel

Follow exactly the administration instructions for Bertanel provided by your doctor. Consult your doctor or pharmacist if you are unsure.

Important warning regarding the dose of Bertanel (methotrexate)

Use Bertanel only once per week for the treatment of rheumatoid arthritis, polyarticular forms of juvenile idiopathic arthritis, or psoriasis. Overuse of Bertanel (methotrexate) can be fatal. Please read section 3 of this leaflet very carefully. If you have any doubts, consult your doctor or pharmacist before using this medicine.

Bertanel should only be prescribed by physicians familiar with the different characteristics of the medication and its mechanism of action.

Bertanel is administered only once per week. Together with your doctor, you can decide on a suitable day each week for receiving your injection.

Incorrect administration of Bertanel may lead to serious adverse effects, including potentially life-threatening adverse reactions.

The recommended dosage is:

Dosage in patients with rheumatoid arthritis

The recommended initial dose is 7.5 mg of methotrexate once weekly.

If this dose is insufficient and the medication is well tolerated, the initial dose of Bertanel may be gradually increased by 2.5 mg. Alternatively, a higher starting dose may be used. The average weekly dose is 15–20 mg. Generally, a weekly dose exceeding 20 mg of Bertanel should not be used. Once the desired therapeutic effect is achieved, the dose should, if possible, be gradually reduced to the lowest effective maintenance dose.

A response to treatment is expected within 4–8 weeks. After discontinuation of Bertanel treatment, symptoms may reappear.

Use in children (over 3 years) and adolescents

Dosage in children (over 3 years) and adolescents with polyarticular forms of juvenile idiopathic arthritis

The recommended dose is 10–15 mg/m² body surface area per week. In cases of inadequate response, the weekly dose may be increased up to 20 mg/m² body surface area per week. However, more frequent monitoring should be performed.

Adults with severe forms of psoriasis vulgaris or psoriatic arthritis

Recommended initial dose (relative to an average adult weighing 70 kg): A single test dose of 2.5–5 mg is recommended to assess toxicity.

If laboratory parameters remain unchanged, treatment may continue approximately one week later with a dose of about 7.5 mg. The dose should be gradually increased (in increments of 5–7.5 mg per week) while monitoring laboratory parameters, until the expected optimal response is achieved. In general, a weekly dose of more than 25 mg of methotrexate should not be exceeded.

Once the desired effect is achieved, the maintenance dose should, as far as possible, be gradually reduced to the lowest effective dose for the patient.

Response to treatment generally occurs after 4–8 weeks. Thereafter, treatment will continue or be discontinued based on the clinical situation and changes in laboratory parameters.

Elderly patients

A dose reduction should be considered in elderly patients due to decreased renal and hepatic function, as well as declining folate reserves associated with aging.

Patients with renal impairment

Patients with renal impairment may require lower doses.

Method and duration of administration

Your doctor will determine the duration of treatment. Bertanel is injected once per week! It is recommended to designate a specific day of the week as the “injection day.”

Bertanel is administered by subcutaneous, intramuscular, or intravenous injection; however, in children and adolescents, intravenous administration should not be used.

Treatment with Bertanel for rheumatoid arthritis, juvenile idiopathic arthritis, psoriasis vulgaris, and psoriatic arthritis is long-term.

Rheumatoid arthritis

Improvement in symptoms can generally be expected within 4–8 weeks of treatment. Symptoms may reappear after discontinuation of Bertanel treatment.

Severe forms of psoriasis vulgaris and psoriatic arthritis (psoriatic arthropathy)

A response to treatment can generally be expected within 4–8 weeks. Depending on the clinical picture and changes in laboratory parameters, treatment will be continued or discontinued.

At the beginning of treatment, Bertanel may be administered by medical personnel. However, your doctor may decide that you can learn to self-inject Bertanel. You will receive appropriate training for this. Under no circumstances should you attempt to self-inject unless you have been specifically trained to do so.

If you use more Bertanel than you should

Follow the administration instructions provided by your doctor. Do not change the dose on your own.

If you suspect that you (or someone else) have administered too much Bertanel, contact your doctor or go immediately to the nearest hospital, or call the Toxicology Information Service at 91 562 04 20. They will determine which measures to take based on the severity of the poisoning.

An overdose of methotrexate can cause severe toxic reactions, including fatal outcomes. Symptoms of overdose may include bleeding or bruising, unusual weakness, mouth sores, nausea, vomiting, black or bloody stools, coughing up blood, or vomiting material resembling coffee grounds, and decreased urine output. See section 4.

Bring the medication with you if you go to the doctor or hospital.

The antidote in case of overdose is calcium folinate.

If you forget to use Bertanel

If you miss a dose, take it within 24 hours of the scheduled day. If the delay is longer, consult your doctor first. Do not take a double dose to make up for missed doses; continue with the prescribed dose. If you have any doubts, consult your doctor.

If you stop treatment with Bertanel

Do not stop treatment with Bertanel unless instructed by your doctor. If you suspect serious adverse effects, consult your doctor immediately.

If you have any further questions about using this medicine, ask your doctor or pharmacist.

4. Possible adverse effects

Like all medicines, this medicine can cause adverse effects, although not everyone will experience them.

Adverse effects generally depend on the dose level and duration of treatment with methotrexate.

Severe adverse effects may also occur at lower doses, which may lead to interruption or discontinuation of therapy.

Adverse effects can appear at any time during treatment.

Most adverse effects are reversible if recognized promptly. However, discontinuation of treatment does not always completely resolve all adverse effects.

Nevertheless, some of the serious adverse effects listed below may, in very rare cases, lead to sudden death.

Some adverse effects may occur after treatment has ended.

Please speak with your doctor.

If you develop any of the following adverse effects, contact your doctor immediately, as they could be signs of potentially life-threatening adverse effects requiring immediate treatment. Your doctor may decide to reduce the dose or discontinue treatment.

Step-by-step instructions for subcutaneous injection:

Step 1:

• Remove from the box the inner pouch containing the pre-filled syringe, cannula, and needle.
• Open the inner pouch by pulling the tab at the corner. Remove the pre-filled syringe.
• Rotate the grey rubber stopper covered with plastic on the syringe, without touching the opening of the pre-filled syringe (see Figure 1).

Figure 1.

Step 2:

• Place the syringe back into the inner pouch. The yellow-colored solution will not spill.
• Check the label on the plastic needle case. The label must be intact (see Figure 2).

Figure 2.

Step 3:

• Remove the cap from the plastic needle case by twisting and pulling. See Figure 3.1.
• Carefully screw the needle, together with the plastic case, onto the syringe until fully tightened. See Figure 3.2.

Figure 3.1 Figure 3.2

Step 4:

• Select the injection site on the abdominal or thigh area and clean it with a cotton swab soaked in alcohol. Do not touch this area before the injection (see Figures 4.1 and 4.2).

Figure 4.1 Figure 4.2

Step 5:

• Remove the cannula cover and set it aside.

• Do not touch the sterile cannula. If this occurs, consult your doctor or pharmacist about using a new cannula. Using two fingers, pinch the skin to form a skin fold, then insert the needle almost vertically into the fold.

Step 6:

• Insert the cannula completely into the skin fold. Then, slowly push the plunger down and inject all the liquid under the skin.

Step 7:

• Carefully remove the cannula and gently apply a cotton swab to the injection site. Do not rub, as this may irritate the injection site.

• To prevent injury, dispose of the used syringe in a sharps container.
