The active substance of Methotrexate Orion tablets, methotrexate, is a substance with the following properties:
Methotrexate is used to treat:
Your doctor will be able to explain how Methotrexate Orion tablets might help you in your particular condition.
Important warning about the dose of Methotrexate Orion (methotrexate):
Take Methotrexate Orion only once a week for the treatment of rheumatoid arthritis, psoriasis or psoriatic arthritis.
Taking too much of Methotrexate Orion (methotrexate) may be fatal. Please read section 3 of this leaflet very carefully. If you have any questions, please talk to your doctor or pharmacist before you take this medicine.
Talk to your doctor, pharmacist or nurse before taking Methotrexate Orion:
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.
Diarrhoea can be a possible side effect of Methotrexate Orion and requires an interruption of therapy. If you suffer from diarrhoea please speak to your doctor.
Methotrexate temporarily affects sperm and egg production. Methotrexate can cause miscarriage and severe birth defects. You 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 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 section “Pregnancy, breast-feeding and fertility”.
Radiotherapy during use of Methotrexate Orion can increase the risk of soft tissue or bone necrosis. If you had skin problems after radiotherapy (radiation dermatitis) or sunburn, these reactions can recur after methotrexate therapy (recall reaction). Psoriasis skin changes can become worse during treatment with methotrexate if you are under UV light.
Enlarged lymph nodes (lymphoma) may occur in patients receiving low dose methotrexate and if this is the case, therapy must be stopped.
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).
Certain other brain disorders (encephalopathy/leukoencephalopathy) have been reported in cancer patients receiving methotrexate. Such side effects cannot be excluded when methotrexate is used to treat other diseases.
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.
Prior to the start of 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:
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.
Children, adolescents and the elderly 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.
Use in children below 3 years of age is not recommended due to the insufficient experience in this age group.
Other concomitant medication may affect the efficacy and safety of this medicine. Methotrexate Orion may also affect the efficacy and safety of other medications.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Remember to tell your doctor about your treatment with Methotrexate Orion, if you are prescribed another medicine while the treatment is still ongoing. It is especially important to tell your doctor if you are taking:
Alcohol as well as large amounts of coffee, caffeine-containing soft drinks and black tea should be avoided during treatment with Methotrexate Orion. Ensure that you drink a lot of fluids during treatment with Methotrexate Orion tablets because dehydration (the reduction of body water) can increase the side effects of methotrexate.
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.
Pregnancy
Do not use Methotrexate Orion during pregnancy except if your doctor has prescribed it for oncology treatment.
Methotrexate can cause birth defects, harm the unborn child or cause miscarriages. 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 Orion Pharma 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.
Breast-feeding
Do not breastfeed during treatment, because methotrexate passes into breast milk. If your attending doctor considers treatment with methotrexate absolutely necessary during the lactation period, you must stop breast- feeding.
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 may cause genetic mutation. 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 3 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”).
Ask your doctor or pharmacist for advice before taking any medicine.
You can feel fatigue and dizziness during Methotrexate Orion treatment. Do not drive or use machines if you have such symptoms.

Proper procedures for safe handling of cytotoxic agents should be administered. Anyone handling methotrexate should wash their hands before and after administering a dose.

Contact with the skin or mucous membrane must be avoided. If methotrexate comes into contact with skin or mucosa, it should be washed immediately and thoroughly with soap and water.
Parents, care givers and patients should be advised to keep methotrexate out of the reach of children, preferably in a locked cupboard.
Accidental ingestion can be lethal for children.
If you take (or someone else has taken) more of the medicine than you should, a physician or nearest hospital casualty department must be contacted immediately.
An overdose of methotrexate can lead to severe toxic reactions, including death. Overdose symptoms may include easy bruising or bleeding, unusual weakness, mouth sores, nausea, vomiting, black or bloody stools, coughing up blood or vomit that looks like coffee grounds, and decreased urinating. See also section 4 “Possible side effects”.
Take your medicine package with you if you go to a doctor or hospital. If you used too much methotrexate you will receive calcium folinate to lessen the side effects of methotrexate.
Take the forgotten dose as soon as you remember if this is within two days. However, if you have missed a dose by more than two days, please contact your doctor for advice. Do not take a double dose to make up for a forgotten dose.
Make sure before your holiday or trip that you have enough of your medicine.
Do not stop taking Methotrexate Orion unless your doctor tells you to. Should you need to stop taking Methotrexate Orion, your doctor will decide which method is the best for you.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
Like all medicines, this medicine can cause side effects, although not everybody gets them. In general, the incidence and severity of adverse reactions of methotrexate are related to dose and frequency of administration. Most adverse reactions are reversible if detected early.
Tell your doctor immediately if you notice any of the following symptoms as these may indicate a serious, potentially life-threatening side effect, which require specific treatment:
Most of the effects listed below will only be seen in patients who are receiving high doses of methotrexate to treat cancer. They are not seen as often and are not as severe at the doses used in the treatment of psoriasis or rheumatoid arthritis.
