Methotrexate 2.5 mg Tablets are one of a group of medicines called antimetabolites which affect cell growth, including the growth of cancer cells.

Methotrexate can be used to treat severe cases of psoriasis (a skin disease) and rheumatoid arthritis (a disease of the joints). It is usually used for patients who have tried other treatments but their illness has not improved. It helps patients with psoriasis by killing the cells in the skin which are growing too quickly. It is these fast growing cells which cause the raised patches of skin in psoriasis.

In the treatment of rheumatoid arthritis, methotrexate is thought to stop or reduce inflammation in the joints by altering the body's defence mechanism in the immune system.

Methotrexate can also be used to treat several kinds of cancer, in particular:

  • acute leukaemias
  • Non-Hodgkin’s lymphoma
  • soft tissue and bone sarcomas
  • solid tumours like breast, lung, head and neck, bladder, cervical, ovarian and testicular cancer.

Methotrexate can be given alone or in combination with other medicines. It is usually used in much higher doses when it is used to treat cancer and it will often be given as an injection rather than tablets.

You should consult your doctor if you are unsure why you have been given Methotrexate 2.5 mg Tablets.


Do not take Methotrexate 2.5 mg Tablets

  • if you know that you are allergic to methotrexate or any of the other ingredients of this medicine (listed in section 6)
  • if you are pregnant, breast-feeding (see section : Pregnancy, breast-feeding and fertility)
  • if you suffer from a problem of excessive drinking (alcoholism)
  • if you have severe liver problems, including fibrosis, alcoholic liver disease and recent or active hepatitis (inflammation of the liver)
  • if you have severe kidney problems, including conditions requiring kidney dialysis
  • if you have any serious blood disorders including severe anaemia or abnormal numbers of blood cells such as low white cells (leucopenia) or low small blood cell numbers (platelets) causing (thrombocytopenia)
  • if you have a medical condition or are receiving medication which lowers your resistance to infection
  • if you are taking antibiotics which prevent the production of folic acid (vitamin B9) such as cotrimoxazole, which are used to treat bacterial infections
  • if you have symptoms which may suggest an active infectious disease (e.g. fever, chills, achiness).

Even though some of the above may be obvious, it is important that your doctor is aware if any of them apply to you.

You and your partner should avoid having a baby if you are being given methotrexate at the time and for at least 6 months after the end of your treatment with methotrexate. See also section “Pregnancy, breast-feeding and fertility”.

Regular check–ups

Whilst being treated with this medicine your doctor will want to monitor your progress on a weekly basis until your therapy is stable. Thereafter, you will be monitored every 2 to 3 months, whilst taking the medicine. These checks may include taking blood and urine samples to check your blood cells and to make sure that your liver and kidneys are working properly. It is important that you do not miss any blood tests.

There may also be a chest x-ray and a physical examination to check for swelling of your lymph nodes (glands in your neck, armpits and groin). Any unusual swellings should also be reported to your doctor.

Methotrexate 2.5 mg Tablets with food and drink

You should not drink alcohol whilst you are taking this medicine.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.


Do not use Methotrexate 2.5 mg Tablets during pregnancy except if your doctor has prescribed it for oncology treatment. 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. It is therefore very important that methotrexate is not given to pregnant women or to women who are planning to become pregnant unless used for oncology treatment.

For non-oncological indications, in women of child-bearing age the possibility of a pregnancy must be ruled out, e.g. by pregnancy tests, before treatment is started. Do not use Methotrexate 2.5 mg Tablets if you are trying to become pregnant. You must avoid becoming pregnant during treatment with methotrexate and for at least 6 months after the end of treatment. Therefore, you must ensure that you are taking effective contraception for the whole of this period (see also section "Warnings and precautions").

If you become pregnant during treatment or suspect you might be pregnant, speak to your doctor as soon as possible. If you do become pregnant during treatment, you should be offered advice regarding the risk of harmful effects on the child through treatment.

If you want to become pregnant, you should speak with your doctor, who may refer you for specialist advice before the planned start of treatment.


Methotrexate 2.5 mg Tablets should not be used during breast-feeding. Methotrexate passes into breast milk. Breast-feeding should be stopped prior to and during treatment with Methotrexate 2.5 mg Tablets.

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 and there is no information regarding higher methotrexate doses. Methotrexate can have a genotoxic effect. This means that the medicine can cause genetic mutations. Methotrexate can affect the production of sperm, which is associated with the possibility of birth defects.

You should avoid fathering a child or to donate semen during treatment with methotrexate and for at least 6 months after the end of treatment. As treatment with methotrexate at higher doses commonly used in cancer treatment can cause infertility and genetic mutations, it may be advisable for male patients treated with methotrexate doses higher than 30 mg/week to consider sperm preservation before the beginning of treatment (see also section "Warnings and precautions").

It may also affect women’s periods; they may become less frequent or stop completely.

Driving and using machines

Methotrexate 2.5 mg Tablets may make you feel drowsy, dizzy or may give you blurred vision. You should not drive or use machines when you first start to take this medicine until you are certain that you are not getting these side effects. If in any doubt, speak to your doctor before you drive or use machines.

Methotrexate 2.5 mg Tablets contains lactose and sodium

These tablets contain lactose (a type of sugar). If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
