Yes. Mefenamic acid is an NSAID commonly used to treat dysmenorrhea (menstrual cramps) because it reduces prostaglandin production, which helps lessen uterine contractions and pain.
Typical adult dosing (users should follow their doctor or the package directions):
- 500 mg at the onset of cramps, then
- 250 mg every 6 hours as needed
- up to a maximum of 1,500 mg per day
- usually for 2–3 days
- take with food to reduce stomach upset
Safety and cautions:
- Common side effects: stomach upset, nausea, heartburn, dizziness.
- Serious risks (like all NSAIDs): stomach ulcers/bleeding, kidney problems, high blood pressure, allergic reactions.
- Do not use if you have a history of peptic ulcers or GI bleeding, severe kidney disease, or an NSAID allergy.
- Not recommended in the third trimester of pregnancy; use in early pregnancy only under medical supervision.
- If you are taking anticoagulants (e.g., warfarin), other NSAIDs, or certain other meds (see below), tell your clinician.
Interactions to be aware of:
- Increases risk of bleeding with anticoagulants or antiplatelet drugs.
- Can interact with methotrexate, lithium, ACE inhibitors/diuretics, and other NSAIDs (avoid combining NSAIDs unless advised).
- May reduce the effect of some antihypertensives; may worsen kidney function when used with certain medicines.
Alternatives and tips:
- Other NSAIDs commonly used for dysmenorrhea include ibuprofen or naproxen, which some people tolerate better.
- Heat, gentle exercise, and relaxation can help in addition to medication.
- If pain persists beyond a few days, or if you have heavy bleeding, fever, vomiting, or severe side effects, consult a healthcare provider.
If you’d like, tell me your age, any medical conditions (like ulcers/kidney problems), and all medications you’re taking, and I can tailor dosing info and flag any potential interactions.
