Is alcohol safe to drink while taking methotrexate?
Alcohol and methotrexate both raise the risk of liver injury. Drinking alcohol while on methotrexate is usually discouraged or limited to very small amounts, depending on your dose, duration of therapy, liver history, and whether you take other liver-affecting medicines. [1]
How much alcohol is considered “okay” with methotrexate?
There is no single safe amount for everyone. Clinicians commonly advise:
- Avoid alcohol entirely if you have liver disease, elevated liver enzymes, heavy alcohol use history, or long-term high-dose methotrexate.
- If alcohol is allowed, keep it minimal and occasional, and follow your prescriber’s specific guidance. [1]
Why is the combination risky?
Methotrexate can cause liver toxicity, and alcohol can also damage the liver. Together, they increase the chance of abnormal liver tests and, in severe cases, liver scarring. Risk can also rise with treatment duration and cumulative exposure. [1]
What about alcohol on the same day as a methotrexate dose?
Many clinicians recommend avoiding alcohol around the time you take methotrexate to reduce added strain on the liver, even if small amounts are otherwise discussed. Use your prescriber’s instructions as the deciding factor. [1]
What symptoms or lab changes should you watch for?
Call your clinician promptly if you develop signs of liver irritation or medication toxicity, such as:
- Yellowing of the skin/eyes (jaundice)
- Dark urine, pale stools
- Persistent nausea/vomiting
- Unusual fatigue or right upper abdominal pain
Your prescriber will also typically monitor blood counts and liver tests while you’re on methotrexate. [1]
Can you take methotrexate with other medications that affect the liver?
Mixing methotrexate with additional liver-stressing drugs (for example, some anti-seizure medicines or other hepatotoxic agents) can further increase risk. Alcohol compounds that concern. Your pharmacist can review your full medication list for interactions and liver risk. [1]
Does methotrexate for different conditions change the alcohol advice?
The general liver-risk issue is the same, but the recommended precautions can differ based on:
- The dose (including whether it’s weekly low-dose for arthritis vs higher dosing for other uses)
- How long you’ll be on therapy
- Your baseline liver risk factors
So your prescriber’s individualized guidance matters most. [1]
If someone already drank alcohol while on methotrexate, what should they do?
Don’t take extra methotrexate doses to “make up” anything. Contact your prescriber for advice, especially if the drinking was more than occasional or you have symptoms. If you have known liver disease or abnormal liver tests, contact the clinic sooner.
