Name Brand Drugs
Most newer drugs are under patent and cost more. Some plans charge a percentage, most a dollar co-payment, for each prescription. In most cases the amount specified allows a one month supply from the local pharmacy. These "name brand" drugs are sometimes fully reimbursed only if you use those listed on a restricted "formulary" that only allows you to use a particular brand of drug for a condition. See plan brochure over overall details and plan website to check the formulary status of any drugs you use.
