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?
• Is a generic version available, and would it suit me? NADAC lists a generic with the same ingredient, strength and dosage form by FDA: CYCLOBENZAPRINE ER 30 MG CAP. Ask your pharmacist or prescriber; do not switch on your own.
• These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
