What is mefenamic acid used for?
Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation. It’s commonly prescribed for short-term relief of conditions such as dental pain and menstrual (period) pain (dysmenorrhea).
How is it used for menstrual cramps (dysmenorrhea)?
Mefenamic acid is used to relieve painful menstrual cramps. People typically take it at the start of symptoms and continue for a short course, as directed by a clinician or label instructions.
What other pain is it used for?
Because it reduces inflammation and pain signaling, mefenamic acid is also used for other types of short-term pain, including:
- Dental pain
- Other acute pain conditions where an NSAID is appropriate
Who should avoid or be careful with it?
Like other NSAIDs, mefenamic acid can increase risk of stomach irritation/ulcers and may worsen kidney problems or raise cardiovascular risk in some patients. It’s usually avoided or used with extra caution in people with a history of NSAID-related ulcers or serious gastrointestinal bleeding, significant kidney disease, or certain heart conditions. If you tell me your age and any key medical conditions (ulcer history, kidney disease, blood thinners, pregnancy), I can help narrow what’s typically recommended.
Can you take it with other medicines?
It’s important not to combine mefenamic acid with other NSAIDs (such as ibuprofen, naproxen, or diclofenac) unless a clinician directs it, because that increases bleeding and stomach-risk. Caution is also needed with blood thinners and some other medications. If you share what you’re taking, I can check common interaction concerns.
How should it be taken (general)
Mefenamic acid is generally taken by mouth and should be taken exactly as prescribed or as written on the product label. Taking it with food can reduce stomach upset.
