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 15 mL? Is it lower than what I would pay through my insurance?
• Is a generic version available, and would it suit me? NADAC lists a generic with the same ingredient, strength and dosage form by FDA: INSULIN DEGLUDEC FLEXTOUCH 100 UNIT/ML PEN. Ask your pharmacist or prescriber; do not switch on your own.
• How much is in the package I am getting? This page uses 15 mL; your package may hold a different amount.
• 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.
