In what circumstance may telephone prescriptions for controlled substances be issued by a prescriber?

Telephone prescriptions for controlled substances may be issued by a prescriber when immediate administration is necessary because this situation aligns with specific exceptions permitted under federal regulations. In emergencies, where a delay could pose a risk to the patient's health, prescribers are allowed to communicate prescriptions over the phone. This protocol helps ensure that patients receive timely access to necessary medications in critical situations.

The other choices do not meet the legal guidelines for telephone prescriptions of controlled substances. Routine medication refills often require a written prescription to ensure proper documentation and oversight. While a patient might request a prescription, this does not, by itself, qualify as an emergency need that would justify a telephone prescription. Additionally, issuing prescriptions for any controlled substance without adhering to specific regulations and justifications could lead to misuse and is not permissible. Therefore, the legal framework emphasizes immediate health needs as the primary justification for allowing telephone prescriptions in these cases.
