What to ask at the counter
None of these figures is your price: what you pay depends on your pharmacy, your insurance, coupons and discounts.
- What is your cash price for 30 tablets? Is it lower than what I would pay through my insurance?
- If you have Medicare Part D: what is my plan’s copay or coinsurance for it? The Part D average on this page is not what you pay.
- These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
