Patient summary

Ponstel is mefenamic acid 250mg and 500mg tablets for dysmenorrhoea and acute pain, a fenamate NSAID that blocks the cyclo-oxygenase enzymes.

Mechanism of action

Mefenamic acid inhibits the cyclo-oxygenase (COX) enzymes, which are responsible for the synthesis of prostaglandins. By reducing prostaglandin production, it diminishes inflammation and pain signals.

Pregnancy and breastfeeding

Pregnancy: Avoid, particularly in the third trimester due to risk of closure of foetal ductus arteriosus. Breastfeeding: Confirm breastfeeding suitability with a qualified clinician or pharmacist before use.
