What type of changes are pharmacists permitted to make to a controlled substance prescription?

Pharmacists are permitted to make changes to a controlled substance prescription with specific limitations to ensure patient safety and prescription integrity. The correct response emphasizes that changes must not increase the original total dosage of the medication. This is crucial because altering the dosage could potentially lead to misuse or abuse of the medication, which is a significant risk associated with controlled substances.

In this context, modifications can include corrections to the dosage form, quantity, or directions for use, provided that these changes do not result in a larger total dosage than what was originally prescribed. For example, if a physician prescribed a total of 300 mg for a certain period, altering the quantity prescribed in a way that reflects a higher total dosage would not be permitted.

The other options suggest incorrect practices that could compromise patient safety or violate regulations surrounding controlled substances. For instance, allowing changes to the patient's name or the prescriber's name can lead to confusion, potential fraud, and issues with accountability. Therefore, pharmacists must adhere to strict guidelines regarding what can be altered within a prescription for controlled substances, ensuring that patient welfare is always prioritized.
