Can I take Advil (ibuprofen) if I’m on methotrexate?
Advil is ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID). In general, people taking methotrexate should only use NSAIDs like ibuprofen if their prescriber says it’s okay, because NSAIDs can raise methotrexate levels in the body and increase the risk of methotrexate toxicity.
What’s the interaction between ibuprofen and methotrexate?
The concern is that ibuprofen may reduce methotrexate clearance (how quickly the body gets rid of it), leading to higher methotrexate exposure. When methotrexate accumulates, side effects can become more likely, especially problems affecting the blood, liver, kidneys, and the lining of the gastrointestinal tract.
What side effects would suggest methotrexate toxicity?
Seek urgent medical advice if you develop symptoms such as:
- Mouth sores, unusual bruising or bleeding, severe fatigue or weakness (possible blood effects)
- Fever or signs of infection
- Severe nausea, vomiting, or diarrhea
- Yellowing of the skin/eyes, dark urine (possible liver issues)
- Decreased urination or new/worsening swelling (possible kidney issues)
Does the risk depend on the methotrexate dose?
Yes. The interaction risk is more important at higher-dose methotrexate regimens (often used in cancer treatment) and when kidney function is reduced. Lower-dose methotrexate (commonly used for conditions like rheumatoid arthritis) can also interact with NSAIDs, but the degree of risk varies by individual factors and monitoring.
How do doctors decide whether ibuprofen is safe with methotrexate?
Clinicians typically consider:
- Methotrexate dose and schedule
- Kidney function
- Age and dehydration risk
- Other medicines that affect kidney function (for example, certain blood pressure drugs or diuretics)
- How often you need pain relief (short course vs repeated use)
They may recommend alternatives and/or closer lab monitoring.
What pain reliever is usually preferred with methotrexate?
A safer default option for many people is acetaminophen (paracetamol) rather than NSAIDs, but you should still confirm with your prescriber because methotrexate can affect the liver and acetaminophen also relies on liver metabolism. Your doctor can advise what’s appropriate for your dose and liver risk.
What should you do before taking Advil?
Before using ibuprofen while on methotrexate:
- Check with the prescribing clinician or pharmacist first.
- Make sure you do not take extra doses of methotrexate unintentionally.
- Stay well hydrated.
- Ask whether you need additional lab monitoring (commonly kidney function and blood counts).

If you share the methotrexate dose (mg/week for low-dose use or mg/m2 for high-dose), your kidney function status (or recent creatinine/eGFR), and your other medications, I can give more tailored, safer guidance.
