1. What Maxtrex Tablets are and what they are used for
Maxtrex Tablets contain the active ingredient methotrexate. Methotrexate is referred to as a cytotoxic, most commonly used to kill cells in tumours. Maxtrex Tablets can also be used to treat severe, uncontrolled psoriasis. It is usually used for patients who have tried other treatments but their condition has not improved.
Methotrexate 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.
Maxtrex is used to treat a wide range of tumours, 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.
Maxtrex can be given alone or in combination with other medicines.
You should consult your doctor if you are unsure why you have been given Maxtrex 10mg Tablets.
2. Before you take Maxtrex
Do not take Maxtrex Tablets if you:
• are allergic (hypersensitive) to methotrexate, or any of the other ingredients of Maxtrex 10mg Tablets, refer to Section 6.
• are pregnant, trying to become pregnant or breast-feeding. Methotrexate may harm your baby (see section on Pregnancy). You and your partner should avoid conception (becoming pregnant or fathering children) for at least three months after your treatment with methotrexate has stopped.
• have severe liver problems (including fibrosis, cirrhosis and recent or active hepatitis).
• have severe kidney problems, including conditions requiring kidney dialysis.
• have any serious blood problems including serious anaemia and clotting problems.
• have a medical condition or are receiving medication which lowers your resistance to infection.
• are taking antibiotics which prevent the production of folic acid (vitamin B9) such as co-trimoxazole, which are used to treat bacterial infections.
• have an active infectious disease (e.g. fever, chills, joint pain).
Take special care with Maxtrex Tablets
Medicines are not always suitable for everyone. Tell your doctor before you take Maxtrex Tablets if you suffer from or have suffered in the past from any of the following conditions:
• have any mild or moderate kidney disease,
• have any blood disorders or anaemia,
• have diarrhoea,
• have gastro-intestinal (digestive) problems,
• have or have ever suffered from mental illness,
• received or you are receiving radiotherapy (x-ray treatment),
• have received any vaccinations recently or you m are due to have any, as methotrexate can reduce
their effect,
• have any symptoms or signs of infection,
• have excess fluid, between the lungs and chest wall or abdominal swelling (ascites).
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.
Taking other medicines
Some medicines can affect the way Maxtrex Tablets work, or Maxtrex Tablets can reduce the effectiveness of other medicines taken at the same time.
These include:
• vaccinations
• aspirin, ibuprofen, indometacin (NSAID's, nonsteroidal anti-inflammatory drugs), which are used for pain or inflammation
• antibiotics (used to treat bacterial infections e.g. chloramphenicol, penicillin, sulphonamides, co-trimoxazole, trimethoprim, ciprofloxacin and tetracyclines)
• thiazides (a group of diuretics for fluid retention e.g bendroflumethiazide)
• hypoglycaemics (used for lowering blood sugar levels e.g metformin)
• p-aminobenzoic acid, acitretin (used to treat psoriasis or skin disorders)
• diphenylhydantoins, phenytoin (used to treat epilepsy)
• probenicid, sulfinpyrazone (used to treat gout)
• vitamin preparations containing folic acid or similar products
• nitrous oxide (a gas used in general anaesthesia).
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Taking Maxtrex Tablets with food and drink
Alcohol should be avoided while receiving methotrexate.
Pregnancy
If you think you might be pregnant, or are planning to get pregnant, tell your doctor before you take Maxtrex Tablets.
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. It may also 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. You and your partner should avoid conception (becoming pregnant or fathering children) for at least three months after your treatment with methotrexate has stopped.
Breast-feeding
You should not take Maxtrex Tablets if you are breast-feeding.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
Maxtrex Tablets may cause some side effects which could affect your ability to drive or use machinery for example drowsiness, loss of co-ordination or blurred vision. If you experience these symptoms, do not drive or use any tools or machinery. The full list of side effects are listed in Section 4.
