Mefenamic Acid is indicated for the treatment of mild to moderate pain from different conditions. This may also be used to lessen pain and blood loss in women with heavy periods. Mefenamic acid helps with heavy and painful menstrual periods because period pain cramps are caused by the production of prostaglandins in the lining of the womb. This relieves period pains and also reduces blood loss in women who have heavy periods.
How does Mefenamic Acid work?
Mefenamic Acid works by blocking the action of a substance in the body called cyclooxygenase (COX). COX is involved in the making of several chemicals in the body which is known as prostaglandins. Prostaglandins are made by the body in response to injury and certain diseases and cause pain, swelling, and inflammation. Mefenamic acid blocks the production of these prostaglandins and so reduces inflammation and pain.
Why use Mefenamic Acid?
Mefenamic Acid is a type of medicine called non-steroidal anti-inflammatory drug (NSAID). NSAIDs are effective in relieving pain and inflammation. This helps prevent the action of prostaglandins after they have already been formed. Mefenamic Acid comes as a capsule for oral use. Each capsule is available as 250 mg. This is a prescription approved by the Food and Drug Administration (FDA).
