Can I take Methotrexate and Ibuprofen together?

Why this happens

Methotrexate is cleared from your body through the kidneys. Ibuprofen interferes with this process in two ways: it reduces blood flow to the kidneys and blocks the specific 'pumps' the kidneys use to flush methotrexate out. This causes the methotrexate to build up in your system.

What you should do

Do not take ibuprofen (or other similar anti-inflammatory drugs like naproxen or aspirin) while taking methotrexate unless your specialist doctor has specifically told you to do so and is monitoring your blood tests closely. For pain relief, paracetamol is usually a safer alternative. If you have already taken both and feel unwell, or develop a sore throat, fever, or unusual bruising, contact your doctor immediately.

Important precautions

Drug Interaction (Kidney/Blood)

Do not take ibuprofen while taking methotrexate unless specifically directed by your specialist. Ibuprofen can stop methotrexate from leaving your body, leading to a dangerous build-up and severe toxicity.

Pregnancy and Conception

Methotrexate causes severe birth defects and miscarriage. You must use effective contraception during treatment and for at least 6 months after stopping. This applies to both men and women.

Asma

Do not take ibuprofen if you have asthma and have ever experienced wheezing, shortness of breath, or a runny nose after taking aspirin or other NSAIDs, as it can trigger a life-threatening asthma attack.

Food and drink warnings

Alcohol

You should strictly limit or avoid alcohol while taking methotrexate. Both alcohol and methotrexate can cause liver damage; using them together significantly increases the risk of serious liver toxicity. Your doctor will advise if a very small amount is permissible based on your blood tests.

Caffeine (Coffee, Tea, Cola)

High intake of caffeine may reduce the effectiveness of methotrexate for some conditions like rheumatoid arthritis. If you notice your symptoms worsening, try to keep your caffeine intake consistent and moderate.

Food (General)

It is best to take ibuprofen with food or a glass of milk. This helps to protect your stomach lining and reduces the chance of indigestion or stomach upset.
