Mefenamic Acid BP is a nonsteroidal anti-inflammatory drug (NSAID) widely used for the relief of menstrual cramps and period-related pain (dysmenorrhea).

It works by reducing the production of prostaglandins—hormone-like substances that trigger uterine contractions and inflammation—helping to ease cramping, lower abdominal pain, and discomfort during menstruation.

Benefits:

Effectively relieves period cramps and lower abdominal pain

Reduces intensity of uterine contractions

Helps decrease heavy menstrual discomfort and inflammation

Provides fast, targeted relief during menstruation

Can improve comfort and daily functioning during periods

Main Side Effects:

Stomach upset or irritation

Nausea

Mefenamic Acid BP is usually taken at the start of menstrual symptoms and for short-term use during the cycle. Taking it with food is recommended to minimise stomach irritation and improve tolerability.
