Ohio Pharmacy Law Practice Test

How must the quantity of controlled substances be written on a prescription?

1. Only numerically

2. Both numerically and alphabetically

3. Only alphabetically

4. As a percentage

The correct answer is: Both numerically and alphabetically

The quantity of controlled substances on a prescription must be written both numerically and alphabetically to ensure clarity and prevent misunderstandings. This dual method of notation serves as a safeguard against potential errors that could arise from misreading the quantity. When the quantity is presented in both formats, it provides a verification mechanism; if there were to be a discrepancy between the two, it can help to identify potential tampering or mistakes. For instance, if a prescription states "30" numerically and "thirty" alphabetically, the pharmacist will have a clear reference to confirm the intended quantity. This practice is particularly important for controlled substances, as they are closely monitored and subject to stringent regulations. By requiring both forms, the law aims to enhance patient safety and reduce the risk of drug abuse or misdispensing. The other options do not meet regulatory requirements for prescriptions of controlled substances in Ohio, as they either limit the format or fail to provide sufficient security measures against errors.
