How pharmacist-on-receipt review works at VLS
When VLS receives a fax or EMR-transmitted prescription, a pharmacist reviews it before compounding begins. They check that the SIG is valid for the compound, that the prescriber is licensed in the patient's state, and that required information is complete. If anything is missing or incorrect, VLS staff call or fax the prescriber's office. The prescriber corrects and resubmits. Compounding does not begin until the Rx is cleared.
This is the traditional compounding pharmacy QA model and it works. The cost is the back-and-forth: an error discovered by the pharmacist requires the prescriber's office to be reached, the correction to be made, and a new Rx to be transmitted. For a routine error like a missing SIG detail, that can add a day or more to the patient's wait.
