Can I take Methotrexate and Tylenol together?

Guida alle interazioni farmacologiche

Taking paracetamol (Tylenol) while on methotrexate is generally safe at standard doses, but there is a small risk that it could increase the levels of methotrexate in your blood or increase the strain on your liver. This is more likely to be a concern if you are taking high doses of methotrexate (usually for cancer) rather than the lower doses used for conditions like rheumatoid arthritis or psoriasis.

It is generally considered safe to take metotrexato e tylenol together, however caution is needed with high doses or long-term use, as both can affect the liver and increase the risk of liver damage.

Both drugs are processed by the liver, and paracetamol may slightly interfere with how the kidneys remove methotrexate from the body. If methotrexate levels rise too high, it can lead to side effects.

Additionally, both drugs can affect liver function, so taking them together requires monitoring.

How to take methotrexate and tylenol safely

  • You can usually take paracetamol with methotrexate, but you must stay within the recommended daily dose of paracetamol (no more than 4,000mg or eight 500mg tablets in 24 hours).

  • Always inform your doctor if you are taking paracetamol regularly, as they may want to monitor your liver function tests more closely.

  • If you notice yellowing of the skin or eyes (jaundice), dark pee, or severe stomach pain, contact your doctor immediately.

Pregnancy and fathering a child

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.

Infection and blood disorders

Methotrexate can suppress your immune system and bone marrow. You must seek immediate medical help if you develop a fever, sore throat, mouth ulcers, or unexplained bruising/bleeding.

Liver function and alcohol consumption

Both medicines are processed by the liver. You must strictly limit or avoid alcohol, as the combination significantly increases the risk of severe liver damage.

Alcol

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 (hepatotoxicity).

Caffeine (coffee, tea, cola)

High intake of caffeine may reduce the effectiveness of methotrexate for some conditions, such as rheumatoid arthritis. If you notice your symptoms worsening, you may need to limit your caffeine intake.

Prodotti lattiero-caseari

Milk and dairy products contain an enzyme called xanthine oxidase which can break down methotrexate in the digestive tract. To ensure you get the full dose, avoid consuming large amounts of dairy at the same time you take your methotrexate tablets.
