Final answer:
When a pharmacy sells schedule II drugs to another pharmacy, the supplying pharmacy keeps a copy of the prescription, as per Controlled Substances Act regulations, to maintain a clear medication transaction record and ensure compliance.
Step-by-step explanation:
When a pharmacy sells schedule II drugs to another pharmacy, the supplying pharmacy, which in this scenario we'll call Pharmacy ABC, retains the copy of the prescription. Controlled substances like schedule II drugs have strict documentation requirements. These medications are heavily regulated to prevent misuse and diversion.
The original prescription is usually sent to the dispensing pharmacy, and the supplying pharmacy must keep a record of the sale, which includes a copy of the prescription, in accordance with the Controlled Substances Act regulations. This helps to maintain a clear chain of custody for the medication and ensures that all transactions can be thoroughly audited if required. The dispensing pharmacy is tasked with keeping patient information and administering the dispensed medication.
