Can you drink alcohol while taking methotrexate?
In general, it’s safest to avoid alcohol or keep it to an absolute minimum while you’re on methotrexate. Methotrexate can affect the liver, and alcohol also stresses the liver. Drinking while using methotrexate increases the risk of liver toxicity.
How much alcohol is “safe”?
There isn’t a universally “safe” amount. Many clinicians advise patients to avoid alcohol altogether, especially if they:
- have liver disease or abnormal liver blood tests
- take other medicines that affect the liver
- take higher methotrexate doses (often used for inflammatory conditions or some cancers)
- have long-term methotrexate use
If you want to drink, the decision should come from your prescribing clinician, who can weigh your dose, your lab results, and your overall risk.
Does the answer change for different methotrexate uses (RA/psoriasis vs cancer)?
Yes. Methotrexate is used for different conditions with different dosing schedules. Liver risk is a concern across uses, but the likelihood of dose-related toxicity and how closely labs are monitored can differ. If you’re taking methotrexate for cancer, the treatment plan and safety monitoring are typically much more controlled—follow the specific instructions from your oncology team.
What are the liver risks and warning signs?
Methotrexate can raise liver enzymes. Heavy or regular alcohol use can add risk. Talk to a clinician promptly if you develop symptoms that could suggest liver problems, such as:
- yellowing of the skin or eyes (jaundice)
- dark urine
- persistent nausea/vomiting
- upper right belly pain
- unusual fatigue
What should you do if you already drank?
If you drank once and it was small, many people will not have problems, but you should contact your prescribing clinician for guidance—especially if you were planning to drink regularly or you have liver history. Your clinician may want to check liver blood tests or adjust monitoring.
Can you drink if you’re also taking folic acid?
Folic acid helps reduce some methotrexate side effects (like mouth sores and certain blood count effects), but it does not make alcohol use risk-free. Even with folic acid, alcohol can still increase liver risk.
Are there safer alternatives to alcohol?
If you’re avoiding alcohol, consider non-alcoholic drinks for social occasions. If you’re unsure, ask your pharmacist or prescribing doctor about your specific regimen and whether any “limit” applies to your case.
