N.J. Stat. § 24:6E-8
Notwithstanding any other law, where a different brand name or nonbrand name drug product of the same established name shall reflect a lower cost to the consumer and no drug product of such established name is included in the latest list of interchangeable drug products published by the council, or where in the professional judgment of the pharmacist there is no valid proof of efficacy for the drug product prescribed, or the pharmacist's patient profile record discloses drug sensitivity, allergies or adverse reactions to the drug product prescribed, or there exists a more appropriate drug product than the drug product prescribed, a different brand name or nonbrand name drug product shall be dispensed by the pharmacist, provided, however, that such action by a pharmacist shall be authorized only if in each case the pharmacist notifies the prescriber of the drug product to be dispensed and the name of the manufacturer thereof, and receives the approval of the prescriber to substitute such drug product for the drug product prescribed. The pharmacist shall be required to indicate on the prescription the date and time of the prescriber's approval and whether the approval was communicated orally or in writing.
