Wyoming MPJE (Pharmacy Jurisprudence) Practice Exam

Which piece of information can a pharmacist NOT change on a C2 prescription?

1. Doctor's signature

2. Dosage form

3. Drug strength

4. Directions

The correct answer is: Doctor's signature

Pharmacists are allowed to make certain modifications to a controlled substance prescription (C2) to ensure its accuracy and appropriateness, such as changing the dosage form, drug strength, or directions. However, the pharmacist is not permitted to change the doctor's signature on the prescription as it serves as a verification of the prescriber's authorization for the medication. This signature is a crucial component in ensuring the legality and validity of the prescription.
