Phental Mefenamic Acid Methotrexate
MajorNSAIDs reduce methotrexate renal clearance, causing bone marrow suppression and renal toxicity.
These medicines can affect each other in a serious way. Do not start taking them together unless your doctor has said it is OK. If you already take both, do not stop either one on your own: speak to your doctor or pharmacist soon.
Clinical management: Avoid with higher-dose methotrexate; with low dose monitor blood counts and renal function.
