What are the required components of a prescription for a controlled substance?

The required components of a prescription for a controlled substance must include essential details to ensure the safe and appropriate dispensing of medication. The correct choice encompasses the patient's full name and address, which is crucial for accurate identification and ensures that the medication is provided to the correct individual.

Additionally, the practitioner's information is vital as it includes their registration and contact details, confirming that they are authorized to prescribe controlled substances. The specifics about the drug, including the name and dosage, are fundamental to ensure the right medication is provided. Moreover, directions for use are essential for safe administration, reducing the risk of misuse or adverse effects.

This comprehensive information serves to protect patient safety, comply with regulatory requirements, and facilitate proper record-keeping by pharmacies and regulatory bodies. The other options lack critical elements that are needed for a valid and legal prescription of controlled substances, such as the complete identification of the patient and practitioner, as well as specific drug information.
