Mefenamic Acid is a therapeutic medication belonging to the NSAID group, primarily used for the short-term treatment of mild to moderate pain and inflammatory conditions. In the UK, it is most commonly utilised to manage dysmenorrhoea (period pain) and menorrhagia (heavy periods), helping patients maintain their daily routine during their menstrual cycle.
The active ingredient in this medication is Mefenamic Acid. Each tablet or capsule also contains a variety of excipients which help the body absorb the medicine effectively. Please refer to the packaging for a full list of inactive ingredients if you have specific allergies.
Many patients report a significant improvement in their quality of life when using Mefenamic Acid for menstrual issues. Statistics suggest that over 70% of women experiencing heavy periods see a noticeable reduction in blood loss when taking NSAIDs like Mefenamic Acid as directed by their healthcare provider.
Every order of Mefenamic Acid includes a Patient Information Leaflet (PIL) which contains essential data regarding the safe use of the product. We strongly recommend reading this document in full before starting your treatment to understand the clinical profile of the medication.
Mefenamic Acid works by inhibiting the enzymes responsible for the production of prostaglandins, which are chemicals in the body that cause pain and inflammation. By lowering prostaglandin levels in the lining of the womb, the medication effectively reduces both the intensity of uterine contractions and the volume of menstrual blood flow.
You should take Mefenamic Acid exactly as instructed by your prescriber, usually by swallowing the tablets whole with a glass of water. It is best to take this medication with or after food to protect your stomach lining and reduce the risk of digestive upset.
The standard dosage for adults treating period pain is typically 500mg taken three times a day. Your specific dose will be determined by your prescriber based on your medical history and the severity of your symptoms to ensure the treatment is both safe and effective for you.
Like all medicines, Mefenamic Acid can cause side effects, though not everyone will experience them. Common side effects can include digestive issues or mild headaches.
- Indigestion or heartburn
- Stomach pain or nausea
- Diarrhoea
- Dizziness
Mefenamic Acid may not be suitable for individuals with a history of stomach ulcers, severe heart failure or asthma sensitive to aspirin. You must disclose your full medical history during your consultation, especially if you are taking other medications such as blood thinners or other NSAIDs.
Mefenamic Acid is often compared to Ibuprofen or Naproxen for pain relief, but it is specifically noted for its effectiveness in reducing heavy menstrual flow. While Ibuprofen is a general-purpose painkiller, Mefenamic Acid is frequently the preferred choice for targeted gynaecological pain management.

Can I take Mefenamic Acid with Paracetamol?
