Final answer:
A written controlled substance prescription must include prescriber and patient information, drug information, date, and signature.
Step-by-step explanation:
A written controlled substance prescription must include several important elements to ensure its legality and proper dispensing. These elements include:
- Prescriber information: The name, address, and DEA (Drug Enforcement Administration) registration number of the prescriber must be clearly stated on the prescription.
- Patient information: The name of the patient, as well as the patient's address and date of birth, should be included.
- Drug information: The name of the controlled substance, its strength, dosage form, quantity prescribed, and directions for use must be clearly stated.
- Date: The date on which the prescription was written should be included.
- Signature: The prescription must be signed by the prescriber, indicating their authorization.
By including these elements, a written controlled substance prescription provides the necessary information for the pharmacist to safely dispense the medication to the patient. It also ensures that the prescription is in compliance with legal requirements.
