What you can prescribe.
State-by-state GLP-1 compounding rules, 503A vs 503B sourcing, FDA shortage list implications, and medical director requirements. Updated April 2026.
Key Facts
Shortage-tied
503A/503B compounding of semaglutide & tirzepatide is permissible only while on the FDA shortage list.
State-specific
Medical director requirements, telemedicine rules, and pharmacy sourcing rules vary by state.
No DEA
needed for GLP-1 alone. Required for Schedule III–V ancillaries like phentermine.
503A vs 503B explained
503A pharmacies are state-licensed compounding pharmacies operating under section 503A of the FD&C Act. They compound patient-specific prescriptions, cannot batch-manufacture for office use, and are regulated primarily by state pharmacy boards. 503B outsourcing facilities register directly with the FDA, operate under cGMP, and can produce bulk compounded medications for office-use dispensing. 503B-sourced GLP-1 programs typically have stronger quality assurance and documented sterility testing.
FDA shortage list: what it means for your business
Section 503A of the FD&C Act allows compounding of drugs on the FDA drug shortage list. When a medication comes off the shortage list, bulk compounding for weight loss becomes legally restricted in most states. Patient-specific compounding with a clinically meaningful difference (dose strength, dosage form, or added ingredient with medical necessity) may remain permissible but requires careful documentation.
Medical director requirements
State requirements for physician oversight of NP-led GLP-1 programs vary widely. Full-practice-authority states (e.g., AZ, CO, OR, WA) allow NPs to practice independently. Reduced-practice states (e.g., NY, IL) require collaborative practice agreements. Restricted-practice states (e.g., TX, FL) require formal physician supervision with specific ratios and chart review requirements.
Telemedicine across state lines
Prescribers must hold an active license in the state where the patient is physically located at the time of the encounter. The Interstate Medical Licensure Compact accelerates multi-state licensing but does not eliminate it. Nurse Licensure Compact covers NPs in most (but not all) states. Audit your state licensure coverage quarterly.
