Can I drink alcohol while taking methotrexate?
It’s generally safest to avoid alcohol or keep it to a minimum while you’re on methotrexate. Methotrexate can stress the liver, and alcohol can also harm the liver, so the combination increases the risk of liver damage. This is the main reason clinicians advise against drinking regularly during methotrexate treatment.
What’s the risk—liver damage and other side effects
The biggest concern is elevated liver enzymes and liver injury. Alcohol may also worsen some methotrexate side effects (like nausea or fatigue), and higher alcohol intake can make liver problems more likely.
Does it matter how much methotrexate I take?
Yes. The lower the dose and the less frequent the dosing, the lower the liver-risk may be, but you still should not treat alcohol as “safe.” Risk also rises with factors like:
- Existing liver disease
- Heavy alcohol use
- Other medicines that affect the liver
What if I only want a small amount (like a single drink)?
Many clinicians advise avoiding alcohol altogether or limiting it to very occasional, small amounts, depending on the methotrexate dose and your liver health. If you’re considering even occasional drinking, the safest move is to ask your prescriber what they consider acceptable for your specific regimen.
When you should not drink at all
Avoid alcohol and contact your prescriber if you have:
- Prior abnormal liver tests on methotrexate
- Hepatitis, cirrhosis, or other chronic liver conditions
- Ongoing heavy drinking habits
- Signs of liver trouble (for example, yellowing of the skin/eyes, dark urine, severe fatigue, or right-upper belly pain)
Check your other medications too
If you take other drugs that can affect the liver or increase methotrexate toxicity, alcohol may make things riskier. Ask your pharmacist or prescriber if you’re on any of these commonly involved categories.
Talk to your clinician (especially if you have labs to monitor)
Methotrexate is often monitored with periodic blood tests, including liver-related labs. If alcohol use is part of your routine, tell your care team so they can guide you and adjust monitoring.
