When prescribing a controlled substance for 30 days or more, what additional information must be included?

When prescribing a controlled substance for a duration of 30 days or more, including the patient's diagnosis is an essential requirement. This is because the diagnosis helps to justify the medical necessity for the prescription, providing validation that the controlled substance is appropriate for the patient's condition. Such information is crucial in the context of controlled substances to prevent misuse and ensure that the prescribing is compliant with regulations aimed at monitoring and controlling these medications.

Involving details such as a patient's diagnosis ensures that there is clear communication about the reason for treatment, facilitating better healthcare decisions and practices. It also helps pharmacy staff in understanding the context of the prescription, which is important for filling prescriptions that involve medications with a higher potential for abuse.

While other options like the patient's address, weight, and practitioner's signature could be relevant in different scenarios, they are not universally mandated as additional information specifically for controlled substances prescribed for a month or longer. The focus here is primarily on ensuring that any controlled substance being prescribed is appropriate and justified based on the patient's specific condition.
