Mefenamic acid is a painkiller than can help to provide relief from painful and heavy periods.

Mefenamic acid relieves painful and heavy periods by blocking the production of hormones called prostaglandins, which can cause your womb to contract painfully if your body produces too much.

Start taking mefenamic acid tablets on the first day of your period, and continue taking them until the pain becomes manageable (usually four days). You take 500mg of mefenamic acid, up to three times a day.
