Common methods of controlling or sharing costs include copayments and incentives to use generic substitutes. A study of prescription drug use and costs for a set of employer groups reveals that a common change in the rate of copayment from $3 to $5 per prescription is estimated to be associated with a 5% decrease in the number of prescriptions, an offsetting increase in ingredient costs per prescription, a 10% decrease in employer costs per person, and an increase in employee costs of approximately the $2 copayment per prescription. | lld:pubmed |
