What it is used for

Mefenamic acid is used to relieve period pain and to reduce heavy menstrual bleeding. It is also used for mild to moderate pain, such as headache, toothache, muscle and joint pain, and pain after injury or surgery. It is usually used for short periods.

How it works

Mefenamic acid blocks cyclo-oxygenase enzymes and lowers the production of prostaglandins. These chemicals cause pain and inflammation, and drive the womb cramps and heavy flow of painful periods.

Questions people ask

Is mefenamic acid good for period pain?

It is commonly used for painful periods because it reduces prostaglandins, which drive cramping. It can also lessen heavy bleeding. If period pain is severe or has changed, see a doctor to check for an underlying cause.

What is the difference between mefenamic acid and paracetamol?

Paracetamol eases pain and fever but has little effect on inflammation. Mefenamic acid is an NSAID that also reduces inflammation, but it has more stomach and kidney side effects. Ask your pharmacist which suits you.

Doctors sometimes prescribe them together for heavy, painful periods, as they work in different ways. Take them together only if your doctor advises.
