Montana Title 37. Professions and Occupations § 37-7-507. Savings passed on

(1) A pharmacist selecting a less expensive drug product must pass on to the purchaser the full amount of the savings realized by the product selection. In no event may the pharmacist charge a different professional fee for dispensing a different drug product than the drug product originally prescribed.

(2) If the prescriber prescribes a drug product by its generic name, the pharmacist must, consistent with reasonable judgment, dispense the lowest retail priced, therapeutically equivalent brand which is in stock.
