When issuing a prescription for a controlled substance, what must the quantity be indicated in?

The requirement for a prescription for a controlled substance to show the quantity both in numeric and word form serves to reduce the ambiguity in how much medication is being prescribed. When quantities are presented in both forms, it acts as a safeguard against potential errors that could arise from misreading or misinterpretation. For instance, if a numeric entry is difficult to read or is misinterpreted, the written word serves as a confirmation of the intended quantity, thereby ensuring clarity and accuracy in the dispensing of medication.

Furthermore, regulatory guidelines stipulate this dual representation to uphold safety standards in prescribing practices for controlled substances, which are subject to higher risk of misuse and potential harm. Relying solely on numeric or written form alone could lead to discrepancies and ultimately compromise patient safety.

In summary, using both numeric and word forms for the quantity of controlled substances on a prescription is essential for clarity, safety, and compliance with legal regulations.
