Patient leaflet - Methofill 50 mg / ml solution for injection in Pre-filled syringe
1. What Methofill is and what it is used for
Methofill contains methotrexate as the active substance.
Methotrexate is a substance with the following properties:
- it interferes with the growth of certain cells in the body that reproduce quickly
- it reduces the activity of the immune system (the body’s own defence mechanism)
- it has anti-inflammatory effects.
Methofill is indicated for the treatment of:
- active rheumatoid arthritis in adult patients
- polyarthritic forms of severe, active juvenile idiopathic arthritis, when the response to nonsteroidal anti-inflammatory drugs (NSAIDs) has been inadequate
- severe recalcitrant disabling psoriasis, which is not adequately responsive to other forms of therapy such as phototherapy, PUVA, and retinoids, and severe psoriatic arthritis in adult patients
- mild to moderate Crohn’s Disease in adult patients when adequate treatment with other medicines is not possible.
Rheumatoid arthritis (RA) is a chronic collagen disease, characterised by inflammation of the synovial membranes (joint membranes). These membranes produce a fluid which acts as a lubricant for many joints. The inflammation causes thickening of the membrane and swelling of the joint.
Juvenile arthritis concerns children and adolescents less than 16 years. Polyarthritic forms are indicated if 5 or more joints are affected within the first 6 months of the disease.
Psoriatic arthritis is a kind of arthritis with psoriatric lesions of the skin and nails, especially at the joints of fingers and toes.
Psoriasis is a common chronic skin disease, characterised by red patches covered by thick, dry, silvery, adherent scales.
Methofill modifies and slows down the progression of the disease.
Crohn’s Disease is a type of inflammatory bowel disease that may affect any part of the gastrointestinal tract causing symptoms such as abdominal pain, diarrhoea, vomiting or weight loss.
2. What you need to know before you use Methofill

Warnings and precautions
Talk to your doctor or pharmacist before taking Methofill if:
- you are elderly or if you feel generally unwell and weak.
- you have problems with the way your liver works.
- you suffer from dehydration (water loss).

Acute bleeding from the lungs in patients with underlying rheumatologic disease has been reported with methotrexate. If you experience symptoms of spitting or coughing up blood you should contact your doctor immediately.
Special precautionary measures for treatment with Methofill
Methotrexate temporarily affects sperm and egg production, which is reversible in most cases. Methotrexate can cause miscarriage and severe birth defects. You must avoid becoming pregnant when using methotrexate and for at least six months after treatment has stopped if you are a woman. If you are a man you should avoid fathering a child if you are being given methotrexate at the time and for at least 3 months after the end of your treatment. See also section “Pregnancy, breast-feeding and fertility”.
Recommended follow-up examinations and precautions:
Even if methotrexate is used in low doses, serious side effects can occur. In order to detect them in time, your doctor must perform monitoring examinations and laboratory tests.
Before therapy:
Before you start treatment, your blood will be checked to see if you have enough blood cells. Your blood will also be tested to check your liver function and to find out if you have hepatitis. Furthermore, serum albumin (a protein in the blood), hepatitis (liver infection) status and kidney function will be checked. The doctor may also decide to run other liver tests, some of these may be images of your liver and others may need a small sample of tissue taken from the liver in order to examine it more closely. Your doctor may also check to see if you have tuberculosis and they may X-ray your chest or perform a lung function test.
During the treatment:
Your doctor may perform the following examinations:
- examination of the oral cavity and the pharynx for changes in the mucous membrane such as inflammation or ulceration
- blood tests/ blood count with number of blood cells and measurement of serum methotrexate levels
- blood test to monitor liver function
- imaging tests to monitor liver condition
- small sample of tissue taken from the liver in order to examine it more closely
- blood test to monitor kidney function
- respiratory tract monitoring and, if necessary, lung function test
It is very important that you appear for these scheduled examinations.
If the results of any of these tests are conspicuous, your doctor will adjust your treatment accordingly.
Elderly patients
Elderly patients under treatment with methotrexate should be monitored closely by a physician so that possible side effects can be detected as early as possible.
Age-related impairment of liver and kidney function as well as low body reserves of the vitamin folic acid in old age require a relatively low dosage of methotrexate.
Methotrexate may affect your immune system and vaccination results. It may also affect the result of immunological tests. Inactive, chronic infections (e.g. herpes zoster [shingles], tuberculosis, hepatitis B or C) may flare up. During therapy with Methofill you must not be vaccinated with live vaccines.
Methotrexate may make your skin more sensitive to sunlight. Avoid intense sun and do not use sunbeds or a sun-lamp without medical advice. To protect your skin from intense sun, wear adequate clothing or use a sunscreen with a high protection factor.
Radiation induced dermatitis and sunburn can reappear during methotrexate therapy (recall reactions). Psoriatic lesions can worsen if you are exposed to UV radiation during treatment with methotrexate.
Enlarged lymph nodes (lymphoma) may occur and therapy must then be stopped.
Diarrhoea can be a toxic effect of Methofill and requires an interruption of therapy. If you suffer from diarrhoea please speak to your doctor.
Encephalopathy (a brain disorder)/leukoencephalopathy (a special disorder of the white brain substance) have been reported in cancer patients receiving methotrexate therapy and cannot be excluded for methotrexate therapy in other disease.
If you, your partner or your caregiver notice new onset or worsening of neurological symptoms including general muscle weakness, disturbance of vision, changes in thinking, memory and orientation leading to confusion and personality changes contact your doctor immediately because these may be symptoms of a very rare, serious brain infection called progressive multifocal leukoencephalopathy (PML).
Other medicines and Methofill
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Please note that this also applies to medicines that you will take in the future.
The effect of the treatment may be affected if Methofill is administered at the same time as certain other drugs:
Antibiotics (medicines to prevent/fight certain infections) such as: tetracyclines, chloramphenicol, and non-absorbable broad-spectrum antibiotics, penicillins, glycopeptides, sulphonamides, ciprofloxacin and cefalotin (sulphur containing medicines that prevent/fight certain infections)
- Non-steroidal anti-inflammatory drugs or salicylates (medicines against pain and/or inflammation)
- Probenecid (medicine against gout)
- Weak organic acids like loop diuretics (“water tablets”) or some medicines used for treatment of pain and inflammatory diseases (e.g. acetylsalicylic acid, diclofenac and ibuprofen) and pyrazole
- Medicinal products, which may have adverse effects on the bone marrow, e.g. trimethoprim-sulphamethoxazole (an antibiotic) and pyrimethamine
- Other medicines used to treat rheumatoid arthritis such as leflunomide, sulfasalazine and azathioprine
- Cyclosporine (for suppressing the immune system)
- Mercaptopurine (a cytostatic agent)
- Retinoids (medicine against psoriasis and other dermatological diseases)
- Theophylline (medicine against bronchial asthma and other lung diseases)
- Proton-pump inhibitors (medicines against stomach trouble such as omeprazole and pantoprazole)
- Hypoglycaemics (medicines that are used to lower the blood sugar)
It is especially important to tell your doctor if you are using:
- Metamizole (synonyms novaminsulfon and dipyrone) (medicine against severe pain and / or fever)
Vitamins containing folic acid may impair the effect of your treatment and should only be taken when advised by your doctor.
Vaccination with live vaccine must be avoided.
Methofill with food, drink and alcohol
Alcohol as well as large amounts of coffee, caffeine-containing soft drinks and black tea should be avoided during treatment with Methofill.
Pregnancy, breast-feeding and fertility
Pregnancy
Do not use Methofill during pregnancy or if you are trying to become pregnant. Methotrexate can cause birth defects, harm the unborn child or cause 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 given to pregnant patients or patients planning to become pregnant. In women of child-bearing age any possibility of pregnancy must be excluded with appropriate measures, e.g. a pregnancy test before starting treatment. You must avoid becoming pregnant whilst taking methotrexate and for at least 6 months after treatment is stopped by using reliable contraception throughout this time (see also section “Warnings and precautions”).
If you do become pregnant during treatment or suspect you might be pregnant, speak to your doctor as soon as possible. You should be offered advice regarding the risk of harmful effects on the child through treatment.
If you wish to become pregnant you should consult your doctor, who may refer you for specialist advice before the planned start of treatment.
Male fertility
The available evidence does not indicate an increased risk of malformations or miscarriage if the father takes methotrexate less than 30 mg/week. However, a risk cannot be completely excluded. Methotrexate may be genotoxic. This means that the medicine may cause genetic mutation. Methotrexate can affect sperm production with the potential to cause birth defects. Therefore, you should avoid fathering a child or donating semen whilst taking methotrexate and for at least 3 months after treatment is stopped.
Breast-feeding
Breast-feeding has to be stopped prior to and during treatment with Methofill.
Driving and using machines
Treatment with Methofill may cause adverse reactions affecting the central nervous system, e.g. tiredness and dizziness. Thus the ability to drive a vehicle and/or to operate machines may, in certain cases, be compromised. If you feel tired or drowsy you should not drive or use machines.
Methofill contains sodium
This medicinal product contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially “sodium-free”.
3. How to use Methofill
Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Your doctor decides on the dosage, which is adjusted individually. Usually it takes 4 – 8 weeks before there is any effect of the treatment.
Methofill is administered subcutaneously (under the skin) by or under the supervision of a physician or healthcare staff as an injection once a week only. Together with your doctor you decide on a suitable weekday each week on which you receive your injection.
