FAQ

  • What is mefenamic acid?

    Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID), which is the name for medicines that are used to treat mild-to-moderate pain and inflammation. Mefenamic acid tablets are usually taken to provide relief from period pain (dysmenorrhoea), reduce the symptoms of heavy periods (menorrhagia), and treat migraines caused by periods.

  • How does mefenamic acid help to relieve period pain?

    Mefenamic acid relieves period pain by blocking the production of prostaglandins, which are hormones released by your womb before and during your period. Prostaglandins cause your womb to contract, and if too many are released then these contractions can become painful. Mefenamic acid causes fewer prostaglandins to be released.

  • How does mefenamic acid help to stop heavy periods?

    Heavy periods, like period pain, can happen when your womb releases too much of the hormone prostaglandin. Mefenamic acid blocks the production of this hormone, causing your periods to become lighter. Mefenamic acid has been shown to reduce heavy bleeding by between 20 to 50%.

  • How long does it take for mefenamic acid to relieve period pain?

    Mefenamic acid takes between 2 - 4 hours to kick in and start easing your period pain. Each 500mg dose of mefenamic acid kills pain for up to 8 hours, so you may need to take it two or three times a day for all-day relief.
