Ponstel Oral Warning
Nonsteroidal anti-inflammatory drugs (including mefenamic acid) may rarely increase the risk for a (sometimes fatal) heart attack or stroke. This effect does not apply to low-dose aspirin. (See Drug Interactions section.) The risk may be greater in people with heart disease or increased risk for heart disease (e.g., due to high blood pressure, diabetes), or with longer use. This drug should not be taken right before or after heart bypass surgery (CABG). Also, this drug may infrequently cause serious (rarely fatal) bleeding from the stomach or intestines. This bleeding can occur without warning symptoms at any time during treatment.
Stop taking this medication and seek immediate medical attention if you notice any of the following rare but very serious side effects: chest pain, severe dizziness, trouble breathing, weakness on one side of the body, sudden vision changes, slurred speech, black stools, persistent stomach/abdominal pain, vomit that looks like coffee grounds. (See also Precautions section.)
Talk with your doctor or pharmacist about the risks and benefits of treatment with this medication.
