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 1 mL? Is it lower than what I would pay through my insurance?
• Which NDC (the 11-digit number on the package) is this? Pharmacies pay $0.00972 to $0.01363 per ML for this product, depending on the NDC.
• It is sold over the counter, so shelf prices vary from store to store: what does it cost per unit here?
• How much is in the package I am getting? This page uses 1 mL; your package may hold a different amount.
• These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
