Is it safe to drink alcohol while taking methotrexate?
Methotrexate can affect the liver, and alcohol also stresses the liver. Because of this combination, many clinicians advise limiting or avoiding alcohol while you’re on methotrexate to lower the risk of liver injury.
How much alcohol is considered “too much” with methotrexate?
There is no single alcohol amount that is universally safe for everyone on methotrexate. Practical guidance is usually conservative: if you do drink, it’s often recommended to keep it to very small amounts and discuss your specific dose, your lab results, and your overall liver risk with your prescribing clinician.
What increases liver risk if you drink alcohol on methotrexate?
Risk is higher if you have any of the following:
- Higher methotrexate doses (or certain long-term regimens)
- Existing liver disease or abnormal liver blood tests
- Regular heavy alcohol use
- Other liver-stressing medicines
- Metabolic conditions that can affect the liver (such as fatty liver)
If you have had abnormal liver function tests before, you should not drink without your clinician’s approval.
What symptoms would suggest liver problems?
Stop alcohol and contact your prescriber urgently if you develop symptoms that can occur with liver injury, such as yellowing of the skin or eyes (jaundice), dark urine, severe fatigue, right upper abdominal pain, persistent nausea/vomiting, or unusual itching.
Does “low-dose” methotrexate for arthritis change the advice?
Even at lower doses used for conditions like rheumatoid arthritis or psoriasis, liver monitoring is still important. Alcohol can still increase liver strain, so the same general caution applies.
What should you do before you decide to drink?
Check your most recent liver blood tests (if you have them) and ask your prescriber or pharmacist for personalized guidance based on:
- Your methotrexate dose and schedule
- Your liver test history
- Any other health conditions or medications
If you tell me your methotrexate dose (mg per week) and the condition you take it for, I can help you form the right questions for your clinician and interpret the usual safety guidance.
