Mefenamic acid is used to treat primary dysmenorrhea (period pain) that is not adequately controlled by suitable lifestyle changes and use of other painkillers such as Ibuprofen and Paracetamol. 

It is an NSAID (Non-steroidal Anti inflamatory drug) which acts to reduce the production of prostaglandins which is a chemical released during a period.

Prostaglandins cause increased contraction of the muscular wall of the uterus. This leads to an increase in pain. By reducing the production of prostaglandins, NSAIDs such as Mefenamic Acid reduce the contraction of the muscular wall of the uterus and subsequently reduce the pain experienced during a period.

How to Use

Recommended Dose:- Take TWO 250mg capsules THREE times a day for up to a maximum of THREE days during any one single period at the onset of period pain or bleeding, whichever comes earlier.

If you (or someone else) take too many of these capsules, you may experience headache, nausea, vomiting, pain in abdomen, blood in stool or vomiting, diarrhoea, disorientation, excitation, coma, drowsiness, dizziness, ringing in ear, fainting, occasionally convulsions. In cases of significant poisoning acute kidney failure and liver damage are possible. Contact your doctor, or hospital immediately for advice.
