Methotrexate
About Methotrexate
Methotrexate is a prescription medication used to manage severe autoimmune conditions like rheumatoid arthritis and severe psoriasis. It serves to calm an overactive immune system, helping to prevent joint damage and clear painful skin plaques. This medicine is typically prescribed when other standard therapies have not provided adequate relief.
To ensure your safety, Methotrexate is typically taken only once a week on a very consistent schedule. You can take this oral medicine with or without food, but taking it with a full glass of water at the same time each week is highly recommended. Incorporating a nutrient-rich diet, staying well-hydrated, and completely avoiding alcohol are essential lifestyle adjustments that support the success of your treatment.
While using this medication, some people may experience common, mild side effects such as nausea, temporary hair thinning, or an upset stomach. However, you must consult your doctor immediately if you experience serious symptoms like a persistent cough, yellowing of the skin, or unusual bruising.
Before starting Methotrexate, talk to your doctor if you have a history of liver disease, kidney problems, or lung conditions. Do not take this medicine if you are pregnant, planning to become pregnant, or breastfeeding, as it can cause severe harm to an unborn baby.
This medicine can interact with alcohol, raising the risk of liver damage, and with certain pain relievers, which can cause the drug to build up to unsafe levels. Pregnant women, breastfeeding mothers, and elderly individuals must consult their doctor or pharmacist before use, as they may require special dosing or monitoring.

Drug Interactions
Drug-Drug Interactions:
Inform your doctor if you are taking any of the following medicines, as they may interact.
- NSAIDs (such as ibuprofen or naproxen): May increase the concentration of Methotrexate in your blood to toxic levels by delaying its clearance through the kidneys.
- Proton Pump Inhibitors (such as omeprazole or pantoprazole): May reduce the kidney's ability to eliminate the medicine, raising the risk of severe side effects.
- Certain Antibiotics (such as trimethoprim/sulfamethoxazole): May increase the risk of severe bone marrow suppression and low blood cell counts.
Drug-Food Interactions:

Habit Forming
Diet & Lifestyle Advise
- Take Folic Acid as Prescribed: Your doctor will likely prescribe a folic acid (vitamin B9) supplement to take on the days you do not take Methotrexate. This helps protect healthy cells and significantly reduces common side effects like mouth sores and nausea.
- Avoid Alcohol Completely: Because this medication is processed by the liver, drinking alcohol while taking it drastically increases your risk of severe liver damage.
- Protect Your Skin from the Sun: This medicine can make your skin highly sensitive to sunlight. Wear protective clothing, apply a high-SPF sunscreen daily, and avoid tanning beds.
- Stay Well-Hydrated: Drink plenty of water throughout the day, especially on the day you take your medicine. Good hydration helps your kidneys flush the medication out of your system safely.
- Practice Good Hand Hygiene: Since this medicine can temporarily lower your body's ability to fight infections, wash your hands frequently and try to avoid close contact with people who are actively sick.
Special Advise
- Women of child-bearing age must use effective contraception whilst on treatment with Methotrexate and for at least 6 months after the last dose.
- Male patients are advised to consult their doctor regarding the possibility of sperm preservation before starting the treatment, as Methotrexate may cause infertility.
- Methotrexate may make you more susceptible to infections; consult your doctor if you develop any signs of infections such as fever, sore throat, breathlessness, jaundice, unexplained bleeding or bruising.
- Your doctor may advise regular blood tests, kidney and liver tests to monitor your condition.
- If you miss a dose of Methotrexate, call your doctor and ask if you should take the missed dose or not.
Patients Concern
Disease/Condition Glossary
Rheumatoid arthritis: It is an autoimmune disease (the body's immune system attacks its tissue) that leads to joint pain and damage. Symptoms of rheumatoid arthritis include pain, inflammation of joints, difficulty moving, and swelling.
Psoriatic arthritis: It is a type of inflammatory arthritis which occurs in patients with psoriasis. It could also occur in patients without psoriasis, particularly in those who have relatives with psoriasis. It affects large joints in the lower extremities, distal joints of toes and fingers, back, and pelvis. Symptoms include inflammation of joints, difficulty moving, swelling, patches of red, scaly skin, and pain.
Psoriasis: It is a chronic autoimmune skin condition that causes the skin to multiply ten times faster than normal. This leads to a rapid build-up of skin cells, causing scaling on the skin surface. Symptoms include inflamed, red, raised patches of skin, soreness around the patches, itching, burning sensations, painful, swollen joints, and dry skin.
Cancer: It is a genetic change in which the cells divide uncontrollably and spread into surrounding tissues. There are two types of cancer, namely benign (localised) and metastatic (spread to the whole body). Cancer growth can be prevented by chemotherapy (with strong antibiotics), radiation, and stem cell therapy.
FAQs
Methotrexate is used to treat active rheumatoid arthritis, including polyarticular juvenile rheumatoid arthritis, severe psoriasis, and severe psoriatic arthritis. It is also used alone or in combination with other medicines to treat breast cancer, lung cancer, head and neck cancer, mycosis fungoides (a type of blood cancer), and advanced-stage non-Hodgkin lymphomas (cancer that starts in the lymphatic system).
Methotrexate acts as an immunosuppressant, which helps in reducing inflammation and preventing joint stiffness, thereby providing relief from rheumatoid arthritis.
Methotrexate works by suppressing the overactive immune system that is responsible for causing psoriasis. Methotrexate interferes with the synthesis of genetic material (DNA) and the growth of cells that multiply faster than usual, thereby helping in treating psoriasis and psoriatic arthritis.
Diarrhoea might be a side-effect of Methotrexate. Stop taking Methotrexate and consult your doctor if you have diarrhoea. Do not take anti-diarrheal medicine on your own.
Methotrexate can affect egg and sperm production and could lead to birth defects. Women of child-bearing potential and men using Methotrexate must use effective contraception while on treatment with Methotrexate and for at least six months after stopping the treatment. Methotrexate can lead to infertility. Therefore, male patients are advised to talk with their doctor regarding the possibility of sperm preservation before starting the treatment with Methotrexate.

Methotrexate may increase your risk of liver and lung problems, especially if you take a high dose. Your doctor, however, will closely monitor you while you are taking Methotrexate. Routine check-ups will reveal any concerns or issues. If you have any concerns about taking Methotrexate, consult your doctor.
Absolutely not. Methotrexate is harmful to a fetus and can cause congenital mutations. Women should wait 90 days after finishing methotrexate before getting pregnant. Men should also wait 90 days before attempting to conceive because methotrexate may impair sperm (sperm formation takes 90 days).
Methotrexate may somewhat reduce your body's response to immunizations, making them less effective than if you were not taking it. It is usually recommended that you be up to date on your immunizations before beginning Methotrexate. If you have any concerns, please seek medical advice from your healthcare professional.
Taking more than the recommended dosage does not provide additional pain relief and can increase the risk of adverse effects.
