Drug interactions between methotrexate and probenecid
Interactions between your drugs
Applies to: probenecid and methotrexate
Using probenecid together with methotrexate can increase the methotrexate levels in your body. This can cause pale skin, easy bruising or bleeding, unusual weakness, mouth sores, nausea, vomiting, black or bloody stools, and urinating less than usual or not at all. If you take both medications together, tell your doctor if you have any of these symptoms. You may need a dose adjustment or special test to safely take both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and food interactions
Applies to: methotrexate
Caffeine may reduce the effectiveness of methotrexate in the treatment of arthritis. If you are receiving methotrexate for arthritis, you may want to limit your intake of caffeine-containing foods and medications. Check with your doctor or pharmacist if you have concerns or are uncertain what products may contain caffeine.
