Before taking this medicine
Mefenamic acid can increase your risk of fatal heart attack or stroke, even if you don’t have any risk factors. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
Mefenamic acid may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using mefenamic acid, especially in older adults.
You should not use mefenamic acid if you are allergic to it, or if you have:

a bowel disorder such as ulcerative colitis or inflammatory bowel disease;
kidney disease; or
