Under what conditions can partial dispensing of C2s occur?

Partial dispensing of Schedule II (C2) controlled substances is allowed when the pharmacy lacks an adequate supply of the medication. In this situation, the pharmacist can dispense a portion of the prescribed quantity and then provide the remainder when the supply issue is resolved. This provision is designed to ensure that patients receive their prescribed medication without unnecessary delays, especially in scenarios where pharmacies might experience shortages.

For C2 medications, there are specific regulations that dictate handling and dispensing practices. If a pharmacist cannot provide the full amount of a C2 prescription due to insufficient stock, they may legally dispense a partial fill, provided that the remaining amount is filled within a certain timeframe as specified by regulation. This ensures that patients have access to their medications while complying with legal requirements.

The other options presented do not align with the legal framework governing the partial dispensing of C2s. While prescriber authorization is important in many aspects of pharmacy practice, it is not a requirement for partial fills based on supply issues. Moreover, the age of the patient does not limit the ability to partially dispense C2 medications. Lastly, having an adequate supply negates the need for a partial fill, as the full prescription could instead be dispensed.
