1. What Methotrexate Oral Solution is and what it is used for

The full name of your medicine is Methotrexate 2mg/ml Oral Solution. In this leaflet the shorter name methotrexate is used.

Methotrexate belongs to a group of medicines called ‘cytotoxics’ which are most commonly used to kill cells and tumours. It is also known as an immunosuppressant which affects the reproduction of the body’s cells and reduces the activity of the immune system.

Methotrexate can be given alone or in combination to treat:

  • Severe active rheumatoid arthritis.
  • Acute Lymphocytic Leukaemia (ALL) in children and adults
  • Malignant trophoblastic tumours
  • Severe psoriasis. It is usually used for patients who have tried other treatments but their condition has not improved.

You should consult your doctor if you are unsure why you have been given Methotrexate 2mg/ml Oral Solution.

2. What you need to know before you take Methotrexate Oral Solution

Do not take methotrexate if :

  • you are allergic to methotrexate or any of the other ingredients of this medicine (listed in section 6). The signs of an allergic reaction may include swelling of your face, lips, tongue or throat, difficulty breathing or swallowing, severe itching of your skin with raised lumps
  • you have severe kidney problems, including conditions requiring kidney dialysis.
  • you have severe liver problems
  • you suffer from alcoholism
  • you have an active infectious disease (e.g. fever, chills, joint pain)
  • you have a medical condition or are receiving medication which lowers your resistance to infection.
  • you have any serious blood problems including bone marrow disorders, serious anaemia and clotting problems.
  • swelling of the mouth or ulcers in the digestive tract.
  • you are pregnant, trying to become pregnant or breast-feeding (see section 2 ‘Pregnancy, breast-feeding and fertility’)
  • you have been given or are going to be given a live vaccine.

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking methotrexate.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking methotrexate if:

  • you have any kidney, lung or liver problems
  • you have diabetes
  • you have any blood disorders or anaemia
  • you have diarrhoea or have been vomiting as you may be dehydrated which can affect how you react to methotrexate
  • you have gastro-intestinal (digestive) problems
  • you have or have ever suffered from mental illness
  • you have received or you are receiving radiotherapy (x-ray treatment)
  • you have received any vaccinations recently or you are due to have any, as methotrexate can reduce their effect
  • you have any symptoms or signs of infection
  • you have excess fluid, between the lungs and chest wall or abdominal swelling (ascites)
  • you have herpes zoster (chicken pox), tuberculosis (TB) or hepatitis B or C.

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.

You must avoid excessive exposure to sunlight and tanning beds.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking methotrexate.

Regular check–ups

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, mouth checks for ulcers, urinalysis and a physical check for swelling of your lymph nodes (glands in your neck, armpits and groin). Any unusual swellings should be reported to your doctor.

If you are having long term treatment, the doctor may send you to the hospital for a liver biopsy.

Other medicines and Methotrexate

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription and herbal medicines. This is because methotrexate can affect the way some other medicines work. Also, some other medicines can affect the way methotrexate works.

In particular tell your doctor or pharmacist if you are taking any of the following:

  • vaccinations
  • medicines for pain or inflammation such as aspirin, ibuprofen, indometacin, amidopyrine, phenylbutazone
  • medicines used to treat bacterial infections (antibiotics) such as chloramphenicol, penicillin, sulphonamides, co-trimoxazole, trimethoprim and tetracyclines
  • diuretics, that reduce fluid retention such as bendroflumethiazide or triamterene
  • medicines for lowering blood sugar levels such as metformin
  • p-aminobenzoic acid and acitretin, used to treat psoriasis or skin disorders
  • medicines used to treat epilepsy such as diphenylhydantoins (phenytoin) and barbiturates such as phenobarbital
  • medicines used to treat gout such as probenecid and sulfinpyrazone
  • vitamin preparations containing folic acid or similar products
  • nitrous oxide (a gas used in general anaesthesia)
  • medicines that help you sleep (tranquillisers)
  • medicines to treat cancer such as doxorubicin, 5-fluorouracil, cisplatin, l-asparaginase or procarbazine
  • pyrimethamine, used to treat malaria
  • leflunomide, used to treat rheumatoid arthritis
  • medicines used to suppress the immune system such as azathioprine, mercaptopurine and ciclosporin
  • omeprazole, used to treat excess stomach acid
  • theophylline, used to treat lung problems such as asthma and COPD
  • cholestryamine, used to lower cholesterol levels.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking Methotrexate

Taking Methotrexate Oral Solution with food, drink and alcohol

Alcohol should be avoided while receiving methotrexate.

Methotrexate can be taken with or without food.

When you have taken your dose, drink some water and swallow it to ensure you have taken your full dose and there is no methotrexate left in your mouth.

Pregnancy, breast-feeding and fertility


  • Do not take methotrexate if you think you might be pregnant, or are planning to get pregnant or breast-feeding. Methotrexate can cause birth defects, harm unborn babies or cause miscarriages and so it is very important that it is not given to pregnant patients or patients planning to become pregnant.
  • You must avoid becoming pregnant whilst taking methotrexate and for at least 6 months after treatment is stopped. Therefore you must ensure reliable contraception is used during this whole period.
  • Before starting treatment, your doctor or nurse should perform a pregnancy test.
  • For those who are taking methotrexate for oncology treatment and wish to become pregnant, you must discuss this with your doctor first.


Methotrexate is excreted in human milk. Because of the potential for serious adverse reactions in infants, breast-feeding must be discontinued before starting treatment.


  • It may affect women’s periods; they may become less frequent or stop completely.
  • Methotrexate can affect sperm and egg production with the potential to cause birth defects.

Driving and using machines

Do not drive, cycle or use any tools or machines until you know how this medicine affects you. This is because you may feel drowsy, you may have a loss of co-ordination and you may get blurred vision. If you are in doubt about whether you can do a particular activity, talk to your doctor or pharmacist.

Methotrexate contains sodium methyl parahydroxybenzoate, sodium ethyl parahydroxybenzoate, sodium and sulphites

  • Sodium methyl and ethyl parahydroxybenzoates - these may cause an allergic reaction which may happen some time after starting the medicine
  • Sodium (0.72mg in 1ml dose) - if you are on a low sodium diet, you need to take this into account
  • Sulphites (from the flavour) – these may rarely cause a severe allergic reaction and difficulty breathing.
