Which statement is true about the rule 'Only one per form' for controlled-substance prescriptions?

• A. Only one per form
• B. Two per form
• C. Three per form
• D. Unlimited

Answer: (A)

This rule trains the focus of a prescription on a single controlled substance. A prescription form is designed to capture all the details for one drug—its name, strength, dosage form, quantity, patient, and instructions—in a clear, auditable way. When only one substance is listed per form, there’s no mix-up about which drug the directions or quantities apply to, which makes verification by the pharmacist and the regulatory tracking systems straightforward and reliable. If a form carried more than one drug, it could blur which instructions apply to which substance and complicate recordkeeping, increasing the risk of errors or noncompliance. Therefore, having one drug per form is the correct standard, while allowing multiple drugs per form would undermine accuracy and oversight.
