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 20 mL? Is it lower than what I would pay through my insurance?
• How much is in the package I am getting? This page uses 20 mL; your package may hold a different amount.
• If you have Medicare Part B: is this drug covered for me in this setting, and what is my share?
• These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
