RSA 318:47-d: Pharmacies; Substituting Generic Drugs.

Pharmacies, including mail-order pharmacies, may substitute generically equivalent drug products for all legend and non-legend prescriptions unless the prescribing practitioner handwrites "medically necessary" on each paper prescription, or uses electronic indications when transmitted electronically, or gives instructions when transmitted orally that the brand name drug product is medically necessary. In this section, "drug product" does not include a biological product.
