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 capsules? Is it lower than what I would pay through my insurance?
• These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
