Final answer:
A physician assistant must include specific information on prescriptions for controlled substances, such as a DEA number, patient details, and drug information, while adhering to scope of practice and state laws.
Step-by-step explanation:
When a registered physician assistant (PA) writes prescriptions for controlled substances, it's important that the prescriptions include certain elements to ensure legal and professional standards are met. Controlled substances like Opium, Heroin, Fentanyl, Morphine, Oxycodone, Vicodin, methadone, and other prescription pain relievers are highly regulated. A PA must include their own DEA registration number on the prescription along with the patient's full name and address, the date of prescribing, the drug name, strength, dosage form, quantity prescribed, directions for use, and the PA's signature. It is essential for a PA to write the prescription within the scope of their practice and state-specific regulations that pertain to a PA's prescriptive authority.
