Is it safe to drink alcohol while taking methotrexate?
Alcohol and methotrexate both affect the liver. Drinking while on methotrexate can raise the risk of liver injury, so many clinicians advise avoiding alcohol or keeping it very limited.
How much alcohol is “too much” on methotrexate?
There isn’t one universal safe amount, because risk depends on factors like dose, how long you’ve been taking methotrexate, your liver history, and other medications. In practice, the safest approach is to avoid alcohol unless your prescriber specifically says it’s okay.
Does the risk change with the methotrexate dose or why you’re taking it?
Yes. Higher methotrexate doses (often used for some cancers) generally carry more risk than the lower weekly doses used for conditions like rheumatoid arthritis and psoriasis. The underlying condition and your overall health (especially liver health) also matter.
What if I already drank before realizing I couldn’t?
If you drank once or a small amount before knowing about alcohol restrictions, it usually doesn’t automatically mean severe harm, but you should contact your prescriber for guidance. Let them know how much you drank and when, and whether you have any symptoms like nausea, fatigue, dark urine, or yellowing of the skin/eyes.
What symptoms should make me call my doctor right away?
Contact your clinician urgently if you develop signs of liver problems (yellow skin/eyes, dark urine, severe fatigue, persistent nausea/vomiting, right upper abdominal pain) or other serious side effects.
What can I ask my doctor to personalize the answer?
Bring up:
- your methotrexate dose and schedule (weekly dose vs other regimen)
- whether you drink alcohol now and how much
- any history of liver disease or hepatitis
- recent liver blood tests (AST/ALT) results
- other alcohol- or liver-affecting medicines (for example, acetaminophen products)
