Other serious side effects may include cardiovascular disease, allergic reactions, stomach ulcers, hemolytic anemia, liver problems, and heart failure. Use is not recommended in the last third of pregnancy and during breastfeeding. Mefenamic acid works by decreasing the production of prostaglandin by the enzyme cyclooxygenase.

Mefenamic acid was approved for medical use in the United States in 1967. It is available as a generic medication. In the United Kingdom 100 tablets of 250 mg costs the NHS about 23 pounds as of 2020. This amount in the United States costs about 135 USD. It is not widely used in the United States due to concerns of relatively greater side effects compared to some other NSAIDs.
