methotrexate

Read all of this leaflet carefully before this medicine is administered to you because it contains important information for you.

•    Keep this leaflet. You may need to read it again.

•    If you have further questions, ask your doctor, pharmacist or nurse.

•    This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours.

1.    What Methotrexate 100 mg/ml solution for injection is and what it is used for

Methotrexate is one of a group of medicines known as antimetabolites. It is used in the treatment of cancer, as well as psoriasis. It stops a substance called dihydrofolate reductase from working. This substance is an enzyme, which is important in “cell growth (replication)”. By inhibiting the enzyme, cancer cells will eventually “die”.

Methotrexate helps patients with psoriasis by killing the cells in the skin that are growing too fast. It is these rapidly growing cells that cause the raised patches of skin in psoriasis.

Pregnancy and breast-feeding

Do not take Methotrexate 100 mg/ml solution for injection if you are pregnant because it causes a variety of malformations or even the death of the foetus. Women must not get pregnant during treatment with Methotrexate 100 mg/ml solution for injection. If you get pregnant during treatment with Methotrexate 100 mg/ml solution for injection, please inform your doctor immediately!

Special indications for contraception:

Methotrexate temporarily influences sperm and egg production. During treatment and up to 6 months after treatment is stopped, you must practice effective contraception. In this respect, it is of no importance whether the male or the female partner takes Methotrexate 100 mg/ml solution for injection!

Do not take Methotrexate 100 mg/ml solution for injection during breast-feeding, since methotrexate is excreted into the breast milk. Methotrexate can seriously harm breast-fed infants.

3.    How Methotrexate 100 mg/ml solution for injection is administered

Dosage

Your doctor will decide on a suitable dose for you. Doses vary considerably and will depend on the underlying disease.

Your doctor may instruct you to take sodium bicarbonate or acetazolamide tablets while receiving your injections to help make sure that methotrexate is not concentrated in the kidneys. If you receive methotrexate in high doses, you will receive calcium folinate as well to lessen the side effects of methotrexate.

It is possible that you will only get methotrexate. In the case of cancer, it is also possible that you will receive so-called combination therapy in which you must take several medications.

Your body weight, age, general condition of health, your response to the drug and whether other medicines are required at the same time will also influence the dose you receive.

Method of Administration Your doctor or nurse will give you Methotrexate 100 mg/ml solution for injection injecting it either into one of your veins (e.g. as bolus or infusion), arteries, or a muscle.

Tests during treatment with Methotrexate

During your treatment, you will have a number of tests, such as regular blood tests to check that appropriate blood levels of methotrexate are attained and that your kidneys are eliminating excess drug properly.

Other tests are performed routinely at the start and during the course of therapy (e.g. chest X-ray, liver function test, full blood count and urinalysis).
