A generic drug is identical to a brand name drug in safety, strength, quality and performance. The generic drug substitution program requires that generic drugs be dispensed. Therefore, if you choose a brand name drug when a generic drug is available, you will need to pay the difference between the costs of the brand name drug and the generic drug.
If you cannot take a generic drug due to a specific medical reason, your doctor should contact CVS Caremark’s Prior Authorization number at 1-800-294-5979 to provide medical information as to why generic medication should not be dispensed. If approved, you will not pay the difference between the brand name drug and the generic drug.
