Compare before filling
Ask the pharmacy for insurance price, cash price, discount-card price, and 90-day price. If the medication is unaffordable, ask your prescriber whether generic, therapeutic alternatives, prior authorization, or assistance programs apply.
Use DailyMed/FDA labels and pharmacy cash-price checks before filling.
