When compounding, how should the quantity be determined for filling a prescription?

In the context of compounding, determining the quantity to fill a prescription should primarily be guided by the prescribing habits of local practitioners. This approach ensures that the pharmacy is aligning its compounded formulations with the actual needs of the patients within its community.

Local prescribing habits reflect the specific medical needs and conditions prevalent in that area, as well as the preferences of healthcare providers who understand their patients best. By considering these habits, a pharmacy can effectively anticipate the demand for certain compounded medications, make informed decisions about the quantities to prepare, and reduce the risk of overproduction or shortages that don't align with patient requirements.

While inventory levels, statewide demand, and patient population surveys offer valuable information, they do not specifically address the immediate needs dictated by local prescribers. Therefore, relying on the local practitioner's prescribing patterns is the most directly relevant and practical approach for determining the quantity of compounded prescriptions, leading to better patient care and more efficient pharmacy operations.
