Can I drink alcohol while taking methotrexate?
Alcohol and methotrexate can both affect the liver. Drinking alcohol while on methotrexate increases the risk of liver irritation or liver damage, so many clinicians advise limiting or avoiding alcohol during treatment.
How strict is the advice—avoid entirely or just limit?
The safest approach is to avoid alcohol unless your prescriber specifically says it’s okay. If your clinician allows drinking, they usually recommend keeping it minimal and staying within a low, clearly defined amount, because the liver-risk issue is cumulative.
What matters most for risk?
Your personal risk can be higher if you:
- already have liver disease (including hepatitis or fatty liver)
- drink heavily at baseline
- take other medicines that also stress the liver
- take higher methotrexate doses or use methotrexate for longer periods
What if I already drank—should I stop methotrexate or call someone?
If you drank a small amount once, you typically do not need to stop methotrexate immediately, but you should contact your prescriber or pharmacist for guidance, especially if you drank more than you normally would. Seek urgent medical advice if you develop symptoms that could suggest liver problems, such as yellowing of the skin/eyes, dark urine, severe fatigue, or persistent right-sided upper abdominal pain.
Does it change if I’m taking methotrexate for cancer vs autoimmune disease?
The interaction concern is still liver-related, but dosing schedules and overall treatment intensity differ, so alcohol advice may be stricter for some regimens. Follow the specific instructions from your oncology or rheumatology team.
What’s a safer way to handle drinking plans?
If you’re planning to drink (for a holiday or event), ask your clinician or pharmacist ahead of time what amount is safe for your particular dose and health history. They can also tell you whether you should hold methotrexate around the time of drinking.
