If a generic drug or interchangeable biological product is substituted for a drug prescribed by brand name or biological product prescribed, the pharmacist or practitioner shall:
1. Note the name of the manufacturer, packer or distributor of the drug or biological product actually dispensed on the prescription; and
2. Indicate the substitution by writing or typing on the label the words "substituted for," or substantially similar language, following the generic name and preceding the brand name of the drug, or following the name of the interchangeable biological product and preceding the brand name of the prescribed biological product, as applicable, unless, at the time the initial substitution of the generic drug or interchangeable biological product for a drug prescribed by brand name or biological product prescribed is made, the person for whom the drug or interchangeable biological product is dispensed elects not to have such an indication written or typed on the label. An election to indicate or not to indicate a substitution on the label pursuant to this subsection applies to both the fill and each refill of the same prescription.
