Can pharmacies still make compounded tirzepatide?
The FDA declared the tirzepatide shortage resolved in December 2024, which ended the exemption that let pharmacies make copies of the approved drug in bulk. Compounding is now generally limited to patient-specific prescriptions, and the FDA says compounded drugs should only be used for patients whose medical needs an FDA-approved drug cannot meet. No matching shortage record was returned in the latest complete FDA check.
