When can partial fills of C11 prescriptions occur?

Partial fills of Schedule II (CII) prescriptions can occur when a pharmacy has limited stock available. This is permissible under federal law. The pharmacy must document the partial fill and the patient has the right to receive the remaining portion of their medication within a specific timeframe, typically 72 hours for CII medications. If the remainder is not filled in that period, a new prescription would be needed.

The rationale for allowing partial fills under these circumstances supports patient needs while ensuring compliance with strict regulations surrounding controlled substances. It enables patients to start their medication even if the pharmacy cannot provide the full quantity at that time. This practice not only helps in managing inventory but also accommodates patients who may require their medication urgently or cannot afford to purchase a larger quantity all at once.
