Ponstan Key Facts
About Ponstan
Ponstan contains mefenamic acid, a nonsteroidal anti-inflammatory drug (NSAID) as its active ingredient. It is used for the treatment of mild to moderate pain. It is also used to treat menstrual cramps. Mefenamic acid blocks the production of prostaglandins, which reduces contraction of the uterus and pain during your period. It also reduces blood loss.
NowPatient offers Ponstan as the generic mefenamic acid or as the brand Ponstan as a treatment for period pain only, following an online consultation with a prescribing clinician.

Answers to Popular Questions About Ponstan
What is Ponstan?
Ponstan is a brand name for mefenamic acid, a non-steroidal anti-inflammatory drug (NSAID) belonging to the fenamate class. It is available as 250 mg and 500 mg capsules. Ponstan is commonly used for the treatment of period pain (dysmenorrhoea), heavy menstrual bleeding (menorrhagia), mild to moderate pain including headache and dental pain, and rheumatic conditions. It is a prescription-only medicine in the UK.
What is the difference between Ponstan and generic mefenamic acid?
Ponstan and generic mefenamic acid contain the same active ingredient and are bioequivalent. Generic mefenamic acid is more commonly prescribed in the UK and is less expensive. There is no clinical difference between the two, and pharmacies will typically dispense the generic version unless the prescriber specifically requests the brand.
How do I take Ponstan?
Take Ponstan 500 mg three times daily, ideally with or after food to reduce stomach irritation. For period pain, treatment is most effective when started at the onset of menstruation or at the first sign of pain and continued for the duration of symptoms, usually 2–3 days. Swallow capsules whole with water. The maximum daily dose is 1500 mg (three 500 mg capsules). Ponstan should not be used for more than 7 consecutive days except on medical advice.
What are the side effects of Ponstan?
Common side effects include nausea, vomiting, diarrhoea, abdominal pain, and indigestion. Like all NSAIDs, Ponstan carries risks of gastrointestinal ulceration and bleeding, particularly with prolonged use. Uncommon side effects include headache, dizziness, and skin rash. Rare serious side effects include severe allergic reactions, blood disorders (haemolytic anaemia), and kidney or liver impairment. Take with food and use the lowest effective dose for the shortest duration to minimise risks.
Who should not take Ponstan?
Ponstan should not be taken by people with active peptic ulcers, inflammatory bowel disease, severe kidney or liver impairment, aspirin-sensitive asthma, or during the third trimester of pregnancy. Caution is needed in elderly patients, those with cardiovascular disease, and those taking anticoagulants. Ponstan is not suitable for children under 12 except on specialist advice.
