Mefenamic acid every how many hours?

Mefenamic acid dosing depends on the condition and the specific tablet/brand strength, but for most adults with pain it’s commonly:

• 500 mg initially, then
• 250 mg every 6 hours as needed (some regimens use 250 mg every 6–8 hours).

Do not exceed the usual maximum (often 1,000 mg/day for self-treatment, and typically 3 days for pain unless a clinician advises otherwise).

If you tell me:

1. your age,
2. the tablet strength (e.g., 250 mg or 500 mg), and
3. what it’s being used for (pain/cramps/fever),
   I can help confirm the most appropriate “every how many hours” schedule.
