What Experts Say

Mefenamic acid is an NSAID that reduces prostaglandins, the chemicals that cause pain, cramps and swelling. This is why it works well for period pain, where prostaglandin levels are high. Relief usually starts within 30 to 60 minutes, and the effect lasts about 6 hours.

Treatment is kept short, normally no longer than 7 days. Food or milk with each dose protects the stomach, and drinking enough water helps the kidneys. Ongoing diarrhea is a sign to stop and call the doctor. Pregnant women, especially in the last trimester, should avoid it.

People with ulcers, kidney disease, heart disease or NSAID triggered asthma should avoid it. In suspected dengue, paracetamol is the safer choice because NSAIDs can increase bleeding. Check labels of other pain relievers to avoid doubling up on NSAIDs. Taking it on an empty stomach is a common cause of heartburn. Tell the doctor about any past stomach bleeding.
