Final answer:
When transferring a Controlled Substance (III-V) to another DEA registrant, the transferring pharmacist must complete DEA Form 222 or maintain proper documentation, ensure the recipient is registered with the DEA, and keep records of the transfer for at least two years.
Step-by-step explanation:
If transferring a Controlled Substance (III-V) to another registrant, the transferring pharmacist must complete a DEA Form 222 for Schedule III and IV controlled substances, or use an alternate electronic system if applicable, that the DEA has approved. For Schedule V substances, documentation that provides traceability for the transfer such as invoices or bills of lading must be maintained. The receiving party must be registered with the DEA. Both parties are responsible for maintaining records of the transfer for at least two years. Furthermore, the quantity and type of controlled substance along with the name, address, and DEA number of the recipient must be clearly documented.
