Can you drink alcohol while taking methotrexate?
In general, alcohol and methotrexate are a risky combination because both can affect the liver. Many clinicians advise avoiding alcohol or keeping it to very small amounts while on methotrexate, especially with higher doses used for conditions like rheumatoid arthritis, psoriasis, or other inflammatory diseases. The key safety concern is liver injury risk.
How much alcohol is considered “too much”?
There isn’t one universal number that applies to everyone. What’s considered safe depends on:
- Your methotrexate dose and schedule
- Whether you have liver disease or heavy alcohol use history
- Other medicines you take that can stress the liver
- How often your liver blood tests are monitored
Because methotrexate can raise liver enzymes, your prescriber may recommend complete avoidance or strict limits, particularly if your liver tests have ever been abnormal.
What could happen if you drink?
Drinking alcohol while on methotrexate can increase the chance of:
- Elevated liver enzymes
- Drug-related hepatitis or more significant liver damage
- Higher overall toxicity when combined with other liver-stressing factors (other medications, obesity, viral hepatitis, etc.)
If you develop symptoms such as yellowing of the skin or eyes, dark urine, severe fatigue, persistent nausea/vomiting, or right upper belly pain, you should seek medical care promptly.
Does it matter if it’s “just once” or a small amount?
Even occasional drinking can be a problem for some people on methotrexate, especially if your dose is moderate to high or you have other risk factors for liver injury. If your clinician hasn’t given a specific “safe amount” for you, it’s safest to avoid alcohol until you confirm with them.
What should you ask your doctor or pharmacist?
When deciding whether alcohol is okay for you, ask your prescriber:
- Whether you should avoid alcohol entirely on your specific methotrexate regimen
- How your liver function tests are being monitored
- Whether any other medications you take also add liver risk (and if alcohol should be avoided because of that)
If you tell me your methotrexate dose (mg and how often) and why you’re taking it, I can help you form specific questions for your clinician.
