Operating on C Street since 1927, Allen Pharmacy is an independent community pharmacy at 333 C Street in downtown San Diego's core, holding California pharmacy license PHY48339 and NPI #1659436079. The retail and compounding pharmacy fills prescriptions from the surrounding downtown medical network, processing scripts generated by community health providers including FamilyHealth at City College nearby. Prescription delivery service extends the pharmacy's reach to homebound patients and downtown residents unable to visit the C Street storefront in person. Compounding capabilities produce custom medication formulations for patients whose treatment plans — prescribed by specialists such as Corrie Broudy, MD in Bankers Hill — require dosage forms, strengths, or ingredient combinations unavailable in commercial manufacturing. Highest-complexity dispensing involves multi-component compounded preparations requiring precise active-ingredient titration, beyond-use dating calculations, and USP <795> non-sterile compounding compliance for individually formulated prescriptions.
