How much does Mefenamic Acid cost in Canada?
Canadian pharmacy listings in our data show Mefenamic Acid priced from about $0.620 per tablet (converted to USD), before shipping. Pack size and pharmacy both affect the final total — see the Canada pricing table for specifics.
Why does Mefenamic Acid cost more in one country than the other?
Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the US price is actually the lower of the two once a program like Cost Plus Drugs is factored in — the assumption that Canada is always cheaper doesn't hold for every drug.
How does the cost of Mefenamic Acid compare with and without insurance?
Your out-of-pocket cost with insurance depends on your specific plan's copay or coinsurance. In some cases, a pharmacy discount program may offer a price lower than your insurance copay. It is advisable to ask your pharmacist to compare the price under your insurance with the price available through a savings card to determine the most affordable option.
Is Mefenamic Acid covered under Medicare plans?
Mefenamic Acid and its brand-name version Ponstel are frequently excluded from the formularies of Medicare Part D and Medicare Advantage prescription drug plans. If you have Medicare coverage, you should check your plan's specific drug list. Patients, regardless of Medicare status, may find lower prices by using a pharmacy savings coupon or discount program.
Is there a brand-name version of Mefenamic Acid?
Yes. Mefenamic Acid is the active ingredient in the brand-name prescription drug Ponstel, which is manufactured by Shionogi. The generic version provides the same therapeutic effect for pain relief from menstrual cramps and moderate pain.
