Is it safe to take ibuprofen (Advil, Motrin) with methotrexate?
Often, a doctor may allow ibuprofen with methotrexate, but the combination can be risky depending on your methotrexate dose, kidney function, age, and other medicines you take. Ibuprofen and other NSAIDs can increase methotrexate levels and raise the chance of methotrexate toxicity, especially if methotrexate is taken at higher doses.
The safest approach is to check with your prescriber or pharmacist before combining them, particularly if you use methotrexate more than once weekly.
What side effects or toxicity would you watch for?
Methotrexate toxicity can show up as problems in the blood or digestive tract, or kidney injury. Seek urgent medical care if you notice symptoms such as:
- Mouth sores or severe sore throat
- Unusual bruising or bleeding, or signs of infection (fever, chills)
- Severe nausea, vomiting, diarrhea, or stomach pain
- Marked tiredness or shortness of breath
- Much lower urine output or swelling (possible kidney issues)
If you’re having concerning symptoms after taking ibuprofen, contact a clinician right away.
Who is at higher risk when combining methotrexate and ibuprofen?
Risk is higher if you:
- Have kidney disease or reduced kidney function
- Are older (kidneys clear drugs more slowly)
- Take higher-dose methotrexate (commonly used for cancer; lower-dose is often for autoimmune diseases)
- Dehydrate (for example, vomiting/diarrhea or poor fluid intake)
- Take other medicines that can also affect kidney function or methotrexate clearance
What can reduce the interaction risk?
Your prescriber may recommend options like:
- Using acetaminophen (paracetamol) instead of ibuprofen for pain or fever
- Using the lowest effective NSAID dose for the shortest time, if an NSAID is necessary
- Monitoring labs (kidney function and blood counts) if you use both
- Avoiding extra NSAIDs or “cold/flu” products that include ibuprofen or similar drugs
Do not change your methotrexate schedule or stop it without medical advice.
What should you do right now?
If you already took them once, don’t panic, but don’t keep repeating doses until you confirm safety with your pharmacist or prescriber. If you tell them:
- Your methotrexate dose (mg) and how often you take it
- Your age
- Any kidney problems
- The ibuprofen dose and when you took it
they can give more specific guidance.
If you want, share your methotrexate dose (and whether it’s weekly dosing for arthritis/psoriasis or used another way) and the ibuprofen dose you plan to take, and I’ll help you think through the typical risk factors and what to ask your clinician.
