ModerateMefenamic acid can make your blood platelets less able to stick together, and platelets are what help a clot form. In people who take warfarin, it may also lengthen the prothrombin time. That is the blood test doctors use to check how long your blood takes to clot. Taken together, your blood may therefore clot more slowly than usual.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
