Ordering dermatology compounds in St Charles is a shipping relationship with a Florida 503A pharmacy. St Charles is a mid-size city of about 71,800 residents in St. Charles County (U.S. Census Bureau, Vintage 2023 population estimates). The Missouri Board of Pharmacy is the state regulator we answer to on nonresident shipments into Missouri.

St Charles sits in the Midwest region, with about 26,000+ licensed prescribers statewide. This figure is a statewide estimate. We prepare patient-specific prescriptions under 503A and ship them from Florida.

Missouri accepts nonresident pharmacy licenses and supports telehealth prescribing for most medication categories. Verify a pharmacy license on the Missouri Board of Pharmacy site for current licensure information.
