For members enrolled in an AmeriHealth prescription drug program, prior authorization and quantity limit requirements will be applied to certain drugs. The purpose of prior authorization is to ensure that drugs are medically necessary and are being used appropriately. Quantity limits are designed to allow a sufficient supply of medication based upon the maximum daily dose and length of therapy approved by the U.S. Food and Drug Administration for a particular drug.
