What information must be included in the documentation for the prescription of controlled substances?

The correct information required for the documentation of a prescription for controlled substances is comprehensive and ensures both legal compliance and patient safety. The essential elements include the patient's name to identify who the medication is for, the drug name to specify which substance is being prescribed, the dosage to indicate how much of the drug the patient should take, the quantity to show how many doses the patient will receive, and the doctor's signature to authorize the prescription legally.

This combination of details is crucial because it helps prevent misuse and abuse of controlled substances, which have a high potential for addiction and are tightly regulated. The doctor's signature serves as a confirmation that the prescription is valid, and the inclusion of dosage and quantity provides clear directions for use.

Other options may lack some of these critical components. For example, mentioning only insurance details or the doctor's contact information does not address the specifics necessary for safe and legal prescribing practices in the context of controlled substances.
