• if you have diabetes mellitus and are being treated with insulin
• if you are dehydrated or have a disease that makes you dehydrated (vomiting, diarrhea, constipation, inflammation of the mucous membranes of the mouth).

Pulmonary haemorrhage has been reported in patients with underlying rheumatological disease receiving methotrexate. If you observe blood when coughing or spitting, you should contact your doctor immediately.

Diarhea may be a possible side effect of this medicine and requires discontinuation of treatment. If you experience diarrhea, please talk to your doctor.

Methotrexate temporarily affects the production of sperm and eggs. Methotrexate may cause spontaneous abortions and severe birth defects. If you are a woman, you should avoid pregnancy during treatment with methotrexate and for at least 6 months after completing treatment. If you are a man, you should avoid fathering a child during treatment with methotrexate and for at least 3 months after completing treatment. See section “Pregnancy, breastfeeding and fertility”.

Radiotherapy during use of this medicine may increase the risk of bone or soft tissue necrosis. If you have skin problems after radiation therapy (radiation causes dermatitis) or sunburn, as these reactions may recur during methotrexate treatment (recall reactions). Changes in the skin caused by psoriasis may worsen during methotrexate treatment if exposed to ultraviolet light.

Methotrexate may make your skin more sensitive to sunlight. Avoid intense sunlight and do not use lamps or sunbeds unless your doctor tells you to. Wear suitable clothing or use high-factor sunscreen to protect your skin from intense sunlight.

Lymph node enlargement (lymphoma) may occur in patients receiving methotrexate at low doses, and if this is the case, treatment should be discontinued.

If you, your partner or caregiver notice the appearance or worsening of neurological symptoms, such as general muscle weakness, visual disturbances, changes in thought, memory and orientation that cause confusion and changes in personality, contact your doctor immediately, as these may be symptoms of a rare and serious brain infection called progressive multifocal leukoencephalopathy (PML).

Cerebral disease (encephalopathy/leukoencephalopathy) has been reported as an adverse reaction in patients receiving methotrexate for cancer treatment. It cannot be ruled out that this may also occur when taking methotrexate for the treatment of other diseases.

Recommended precautions and follow-up examinations

Even when used at low doses, methotrexate may cause serious adverse effects. Your doctor will perform blood and urine tests to ensure that any adverse effects are identified quickly.

Before starting treatment:

Before starting treatment, a blood test will be performed to confirm that you have sufficient blood cells. Your blood will also be tested to check liver function and to see if you have hepatitis. In addition, your albumin (a protein in the blood) levels will be checked, as well as your liver and kidney function. Your doctor may also decide to perform other liver tests, some of which may involve imaging of your liver and others may require a small sample of liver tissue to be taken for closer examination. Your doctor may also check for tuberculosis and perform a chest X-ray or lung function test.

During treatment:

Your doctor may perform the following tests:

• oral cavity and pharynx examination to detect changes in the mucous membranes such as inflammation or ulceration
• blood test/complete blood count with the number of blood cells and measurement of methotrexate levels in the blood
• blood test to control liver function
• imaging tests to control liver status
• small sample of liver tissue taken for closer examination
• blood test to control kidney function
• control of respiratory pathways and, if necessary, lung function test.

It is very important that you attend these scheduled examinations. If the results of any of these tests are abnormal, your doctor will adjust your treatment accordingly.

Children, adolescents and the elderly

Children, adolescents and the elderly treated with this medicine should be under close medical supervision to identify any possible adverse effects as soon as possible.

The age-related deterioration of liver and kidney function, as well as the low vitamin B12 reserves in the elderly, require a relatively low dose of methotrexate.

This medicine is not recommended for children under 3 years of age because the experience with the use of this medicine is insufficient in this age group.

Other medicines and Metotrexato Semanal Orion Pharma

The simultaneous use of other medicines may affect the efficacy and safety of this medicine. This medicine may also affect the efficacy and safety of other medicines.

Inform your doctor or pharmacist if you are taking, have recently taken or may need to take any other medicine. Remember to inform your doctor about your treatment with this medicine if you are prescribed another medicine while the treatment is still ongoing. It is especially important to inform your doctor if you are taking:

• metamizol (synonyms: novaminsulfon and dipirona) (painkiller and/or fever reducer)
• antibiotics (medicines to prevent/combat certain infections) such as penicillins, sulfonamides, ciprofloxacin, cephalothin, trimethoprim/sulfamethoxazole, tetracycline and chloramphenicol. For example, penicillins such as amoxicillin may reduce the excretion of methotrexate, potentially causing an increase in adverse effects

• other medicines used to treat rheumatoid arthritis such as leflunomide, sulfasalazine and azathioprine
• some painkillers and/or anti-inflammatory medicines known as non-steroidal anti-inflammatory drugs (e.g. ibuprofen, diclofenac, salicylates such as acetylsalicylic acid)
• pirimetamina (for the prevention and treatment of malaria)
• antineoplastic agents (e.g. mercaptopurine, 5-fluorouracil, doxorubicin and procarbazine)
• antiepileptic medicines (prevention of seizures)
• omeprazole or pantoprazole (medicines used to stop stomach acid production)
• diuretics (tablets to urinate)
• medicines to reduce blood sugar levels, such as metformin
• colestiramine (medicine that binds to bile acids and may be used, for example, to reduce cholesterol levels)
• ciclosporin (medicine that may inhibit or prevent the immune response)
• retinoids (for the treatment of psoriasis and other skin diseases)
• oral contraceptives
• barbiturates (sleeping pills)
• sedatives
• nitrous oxide (used for general anesthesia)
• probenecid (medicine used to treat gout)
• theophylline (medicine used to treat respiratory diseases)

• live vaccines.

Taking Metotrexato Semanal Orion Pharma with food, drinks and alcohol

During treatment with this medicine, you should avoid consuming alcohol, as well as excessive consumption of coffee, caffeinated soft drinks and black tea. Make sure you drink plenty of fluids during treatment with Metotrexato Orion Pharma tablets as dehydration (reduction of body water) may increase the adverse effects of methotrexate.

Pregnancy, breastfeeding and fertility

If you are pregnant or breastfeeding, think you may be pregnant or intend to become pregnant, consult your doctor or pharmacist before using this medicine.

Pregnancy

Nouse this medicine during pregnancy, except if your doctor has prescribed it as cancer treatment.

Methotrexate may cause birth defects, harm the fetus or cause miscarriages. It is associated with cranial, facial, heart and vascular, brain and limb malformations. Therefore, it is very important that methotrexate is not administered to pregnant women or those planning to become pregnant, except if used as cancer treatment.

In non-oncological indications, women of childbearing age should exclude any possibility of pregnancy by, for example, a pregnancy test, before starting treatment.

Do not use this medicine if you are trying to become pregnant. You should avoid becoming pregnant while taking methotrexate and for at least 6 months after completing treatment. To do this, you should ensure that you are using reliable contraceptive methods during that time (see also section “Warnings and precautions”).

If you become pregnant during treatment or suspect you may be pregnant, consult your doctor as soon as possible. If you become pregnant during treatment, you should receive information about the risk of harm to the child during treatment.

If you want to become pregnant, consult your doctor, who may refer you to a specialist to inform you before starting treatment.

Breastfeeding

Do not breastfeed your child during treatment, as methotrexate passes into breast milk. If your doctor considers it absolutely necessary to continue treatment with methotrexate during the breastfeeding period, you should stop breastfeeding.

Male fertility

The available data do not indicate a higher risk of malformations or miscarriages if the father takes a methotrexate dose of less than 30 mg/week. However, this risk cannot be completely ruled out, and there is no information on higher doses of methotrexate. Methotrexate may be genotoxic. This means that the medicine may cause genetic mutations. Methotrexate may affect sperm production, which is associated with the possibility of birth defects.

You should avoid fathering a child or donating semen during treatment with methotrexate and for at least 3 months after completing treatment. Since cancer treatment with higher doses of methotrexate may cause infertility and genetic mutations, it is recommended that men treated with methotrexate doses higher than 30 mg/week consider semen conservation before starting treatment (see also section “Warnings and precautions”).

Consult your doctor or pharmacist before taking any medicine.

You may feel tired and dizzy during treatment with this medicine. Do not drive or operate machines if you have these symptoms.
