What constitutes a “valid prescription” for controlled substances?

A valid prescription for controlled substances must be issued by a prescriber who is licensed and acting within the scope of their practice for a legitimate medical purpose. This means that the prescriber must have a valid patient-provider relationship, conduct an appropriate evaluation of the patient, and prescribe the medication based on a medically sound rationale. This ensures that the prescribing of controlled substances is done ethically and responsibly, minimizing the risk of misuse or abuse.

In contrast, other choices provided do not meet the established criteria for a valid prescription. Prescription validity does not extend to any medication written by any provider, as prescribers must have relevant training and authority. Additionally, a valid prescription cannot be established without consultation between the provider and the patient, as this is essential for confirming the patient's need for the medication. Lastly, a prescription cannot be handwritten by the patient themselves, as this would not involve the necessary prescriptive authority and oversight by a licensed provider. By adhering to these standards, the integrity and safety of prescribing controlled substances can be maintained.
