Can you drink alcohol while taking methotrexate?
In most cases, alcohol and methotrexate should be avoided or kept to an absolute minimum. Methotrexate can affect the liver, and alcohol also stresses the liver. Using both increases the risk of liver injury.
How much alcohol is considered “safe”?
There isn’t a universally “safe” amount that applies to everyone on methotrexate. Many clinicians recommend no alcohol, or only very small amounts, depending on:
- your methotrexate dose (higher doses generally mean higher risk),
- your liver history (fatty liver, hepatitis, prior abnormal liver tests),
- other liver-stressing medicines,
- whether you use methotrexate weekly (for arthritis/autoimmune disease) or in other regimens.
If you tell me your dose and what methotrexate is for (e.g., rheumatoid arthritis, psoriasis, cancer), I can help you interpret the usual risk factors to discuss with your prescriber.
What could happen if you drink while on methotrexate?
The main concern is liver toxicity, which can show up as abnormal liver blood tests and, in more serious cases, symptoms such as:
- right upper belly pain,
- unusual fatigue,
- nausea,
- yellowing of the skin/eyes (jaundice).
Alcohol may also worsen side effects like nausea or mouth sores in some people.
When should you avoid alcohol completely?
Avoid alcohol if any of the following apply:
- you have abnormal liver tests or known liver disease,
- you drink heavily or binge drink,
- you are taking other medications that can harm the liver,
- you are on methotrexate for a condition where your dosing is higher or monitored more closely,
- you have risk factors for fatty liver (for example, uncontrolled diabetes or obesity).
What should you do instead?
- Follow your prescriber’s guidance about alcohol (many recommend “none”).
- Keep up with scheduled monitoring (commonly periodic liver blood tests, depending on your regimen).
- If you’ve already had alcohol, don’t panic—contact your clinician for advice, especially if you develop symptoms or your recent labs were abnormal.
Can you drink if you’re just starting methotrexate?
It’s still best to avoid alcohol when starting, since your clinician may want baseline and follow-up labs and may be assessing your tolerance. If you plan to drink around the time you start, check with the prescribing team first.

I don’t have access to your specific label instructions or your prescriber’s guidance in this chat. If you share the methotrexate dose (mg) and your schedule (usually once weekly for autoimmune conditions), I can help you draft a quick question to ask your clinician about alcohol limits.
If you want, paste the exact “alcohol” warning wording from your methotrexate prescription label, and I’ll translate it into plain language.
