Product Description

Why it's used

Mefenamic acid is used to treat mild to moderate pain and dysmenorrhea (menstrual cramps).

It's approved to treat pain in people who are least 14 years old for no longer than seven days. It's approved to treat menstrual cramps for no longer than two to three days.

How it works

Mefenamic acid belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs help reduce pain, inflammation, and fever.

It isn't known how this medication works to decrease pain. It may help reduce swelling by lowering levels of prostaglandin, a hormone-like substance that usually causes inflammation.

To help avoid interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs you're taking. To find out how this drug might interact with something else you're taking, talk to your doctor or pharmacist.
