Is alcohol safe while taking methotrexate?
Usually, the safest advice is to avoid alcohol (or keep it very limited) because methotrexate can affect the liver, and alcohol can increase that risk. Drinking while on methotrexate may raise the chance of liver injury, especially with higher doses, long-term use, or existing liver disease.
How much alcohol can you drink?
There is no single “safe” amount that fits everyone on methotrexate. Many clinicians recommend avoiding alcohol altogether, or only drinking rarely and in small amounts if your prescriber says it’s okay. Your risk is higher if you:
- Drink heavily or binge drink
- Have liver disease (fatty liver, hepatitis, cirrhosis)
- Take other liver-impacting medicines
- Use methotrexate at higher weekly doses
- Have abnormal liver blood tests
If you tell me your methotrexate dose, how often you drink, and what condition it’s for (rheumatoid arthritis, psoriasis, etc.), I can help you map your situation to common risk factors to discuss with your prescriber.
What happens if you drink anyway?
Alcohol plus methotrexate increases the chance of liver strain. Watch for signs that should prompt urgent medical advice, such as:
- Yellowing of skin/eyes (jaundice)
- Dark urine
- Persistent nausea/vomiting
- Right upper belly pain
- Unusual fatigue
- Easy bruising or bleeding
Even without symptoms, methotrexate commonly requires periodic blood tests to monitor liver enzymes, blood counts, and kidney function.
Does it matter whether it’s weekly low-dose vs high-dose?
Yes. Methotrexate given weekly at low doses for inflammatory conditions is still associated with liver risk, but the likelihood of problems generally rises with higher doses (such as some cancer regimens) and with ongoing alcohol use.
Can I drink if I’m also taking folic acid?
Folic acid helps reduce some side effects of methotrexate (like mouth sores and some blood count issues), but it does not reliably remove the liver risk from alcohol. So it usually does not mean alcohol is automatically safe.
What should you do before drinking?
Call or message your prescriber or pharmacist and ask what they recommend for your specific regimen. If you recently had elevated liver tests, your prescriber will be especially cautious about alcohol.
If you share:
- Your methotrexate dose (mg and how often)
- Whether you take folic acid
- Your most recent liver blood test results (if you know them)
- Any liver history or other medications
I can help you prepare a focused question for your clinician.
