FAQs
Answers to Popular Questions About Mefenamic Acid
What is Mefenamic Acid?
Mefenamic acid is a non-steroidal anti-inflammatory drug (NSAID) belonging to the fenamate class. It is available as 250 mg and 500 mg capsules under the brand name Ponstan. Mefenamic acid is commonly prescribed in the UK for period pain (dysmenorrhea), heavy menstrual bleeding (menorrhagia), and mild to moderate pain. It is a prescription-only medicine and is particularly useful for menstrual-related conditions because of its dual analgesic and anti-inflammatory properties.
What is Mefenamic Acid used for?
Mefenamic acid is primarily used for primary dysmenorrhea (period pain), menorrhagia (heavy periods — it can reduce menstrual blood loss by approximately 25–30%), mild to moderate pain (headache, dental pain, muscular pain), and post-operative pain. It is also used for rheumatic conditions and osteoarthritis. Its particular efficacy for menstrual conditions makes it one of the most commonly prescribed NSAIDs for women’s health in the UK.
How does Mefenamic Acid work?
Mefenamic acid inhibits cyclooxygenase (COX) enzymes, reducing the production of prostaglandins. Prostaglandins are responsible for inflammation, pain, and uterine contractions. In dysmenorrhea, excessive prostaglandin production causes painful uterine cramps. By reducing prostaglandin levels, mefenamic acid relieves pain and also reduces the volume of menstrual bleeding. It may also have additional effects on prostaglandin receptors that enhance its analgesic properties.
What is the usual dose of Mefenamic Acid?
For period pain and heavy periods: 500 mg three times daily, starting on the first day of menstrual bleeding (or when pain begins) and continuing for the duration of symptoms (usually 2–5 days). For other pain: 500 mg three times daily. Always take mefenamic acid with or after food to reduce stomach irritation. Treatment for pain should not exceed 7 days unless directed by a doctor. Swallow capsules whole with water.
When should I start taking Mefenamic Acid for period pain?
For best results, start taking mefenamic acid at the onset of menstrual bleeding or as soon as period pain begins — ideally before the pain becomes severe. Early treatment allows the medication to suppress prostaglandin production before it reaches high levels. Some women find it helpful to start 1–2 days before the expected start of their period if the onset of pain is predictable. Continue for the duration of heavy bleeding or pain.
What are the side effects of Mefenamic Acid?
Common side effects include nausea, vomiting, diarrhea (more common with mefenamic acid than other NSAIDs), abdominal pain, and indigestion. Taking it with food reduces gastric side effects. Less common side effects include headache, dizziness, and drowsiness. Serious but rare effects include gastric ulceration and bleeding, kidney impairment, and severe skin reactions. Mefenamic acid should be stopped if diarrhea occurs and persists. Long-term NSAID use carries cardiovascular and gastrointestinal risks.
Who should not take Mefenamic Acid?
Mefenamic acid should not be taken by people with active peptic ulcer disease or GI bleeding, severe heart failure, severe kidney or liver impairment, or aspirin/NSAID hypersensitivity (including those with NSAID-induced asthma). Caution in patients with asthma, cardiovascular disease, inflammatory bowel disease, or those taking anticoagulants. It is not recommended in the third trimester of pregnancy.
Can I take Mefenamic Acid during pregnancy?
Mefenamic acid should be avoided during the third trimester of pregnancy as NSAIDs can cause premature closure of the ductus arteriosus, delay labour, and affect foetal kidney function. Use in the first and second trimesters should only be considered if clearly necessary and at the lowest dose for the shortest time. Paracetamol is the preferred analgesic throughout pregnancy.
