Mefenamic acid is a medicine used to manage period-related discomfort. Limiting the production of inflammatory proteins keeps painful cramping signals dampened, allowing for more manageable monthly cycles.
Mefenamic acid belongs to the nonsteroidal anti-inflammatory drug (NSAID) class, which works to ease pain and reduce swelling. It is the active ingredient in products such as Ponstel, a common over-the-counter option in Australia.
Mefenamic acid is commonly used to ease menstrual cramps, tension-type headaches, toothaches after dental work, muscle strains, and mild joint discomfort. People who experience short-term, moderate pain often choose medicines that contain this active compound, especially when they need fast relief.
After you swallow a tablet, the medicine is absorbed into your bloodstream and travels to the sites of discomfort. It reduces the production of prostaglandins — chemical messengers that signal pain and cause inflammation — so the affected area feels less sore and swollen.
Use mefenamic acid with caution if you are pregnant, planning to become pregnant, or are nursing, because NSAIDs can affect fetal and infant development. People with a history of stomach ulcers, bleeding disorders, kidney disease, heart disease, asthma, or an allergy to other NSAIDs should also be careful.
Alcohol can increase the risk of stomach irritation, and other blood-thinning agents or additional NSAIDs may raise bleeding risk. Certain foods high in fat can slow absorption, but the most reliable way to know about interactions is to read the specific medication's labeling, which lists detailed warnings.
Older adults, people with prior stomach ulcers, those with kidney or heart problems, and individuals taking blood-thinners tend to experience side effects more frequently. Anyone with asthma or a known NSAID allergy should be especially vigilant.
Keep tablets in a cool, dry place away from direct sunlight and moisture, such as a cupboard rather than a bathroom cabinet. Do not freeze or expose them to extreme heat. Most mefenamic acid products are intended for short-term use, though some formulations may be prescribed for longer periods under professional guidance. Remember that different Ponstel products can vary in strength and dosing instructions.
For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
