Can you drink alcohol while taking methotrexate?
Alcohol and methotrexate together can increase the risk of liver injury. Both can stress the liver, so many prescribers advise limiting or avoiding alcohol during methotrexate treatment. The higher the methotrexate dose (and the longer you take it), the more important it is to discuss alcohol use with your clinician.
What is the main risk from alcohol + methotrexate?
The key concern is hepatotoxicity (liver damage). Methotrexate can raise liver enzymes and, in some people, lead to liver scarring over time. Alcohol use can add to that risk, making liver monitoring more important.
Does the risk depend on your methotrexate dose or how often you drink?
Yes. Liver risk is more likely when:
- Methotrexate dose is higher
- Treatment lasts longer
- You drink more alcohol (especially heavy or frequent drinking)
- You have other liver risk factors (for example, hepatitis, obesity, diabetes, or pre-existing liver disease)
Clinicians often recommend stricter alcohol avoidance at higher doses or if blood tests show liver irritation.
Is it safe to have a small amount of alcohol occasionally?
Some clinicians allow small, occasional alcohol intake with methotrexate, but the safest approach is to follow your prescriber’s guidance. Because methotrexate can affect the liver even when you feel fine, “moderate” drinking is not universally considered safe.
What symptoms should you watch for?
Seek medical advice promptly if you develop signs that could point to liver problems, such as:
- Unusual fatigue or weakness
- Yellowing of the skin or eyes (jaundice)
- Dark urine or pale stools
- Right upper abdominal pain
- Persistent nausea or loss of appetite
Should you get liver tests if you drink alcohol on methotrexate?
If you are on methotrexate, liver blood tests are commonly used to monitor safety. Alcohol makes those checks more important, and your clinician may increase monitoring or adjust treatment if liver enzymes rise.
Are there other interactions that affect the liver?
Alcohol is not the only issue. Tell your clinician about all medicines and supplements you take, especially:
- Other liver-stressing drugs
- Over-the-counter pain relievers (depending on what you use)
- Herbal products or supplements, which can sometimes be hepatotoxic
Your prescriber can help decide what is safe alongside methotrexate.
What should you do if you already drank alcohol after a methotrexate dose?
If you drank once and only lightly, it often doesn’t cause immediate harm, but you should contact your prescriber for personalized advice—especially if you drank heavily or have liver risk factors. If you feel unwell or have liver symptoms, seek care right away.
How to reduce risk
Common harm-reduction steps include:
- Avoiding heavy alcohol or stopping alcohol during methotrexate therapy if your prescriber advises it
- Keeping scheduled lab monitoring
- Taking methotrexate exactly as prescribed
- Using folic acid or folate as directed (often prescribed to reduce some side effects)
If you share your methotrexate dose (mg per week), how often you drink, and your condition (rheumatoid arthritis, psoriasis, etc.), I can help you frame the safest questions to ask your clinician.
