Compounded semaglutide voluntary Class II recall, April 2026
Compounded semaglutide · Announced 2026-04-12 · Last reviewed May 2026
Following FDA inspection findings of inconsistent dose-to-dose potency in compounded semaglutide vials, multiple 503A compounding pharmacies have issued voluntary Class II recalls covering specified lots. The FDA classifies this as Class II, meaning the products may cause temporary or medically reversible adverse health consequences (under- or over-dosing during titration). Patients currently using compounded semaglutide should check their vial labels against the affected lot lists published by their dispensing pharmacy and follow up with their prescriber to verify their current vial is unaffected or to arrange replacement.
What's affected
- Specific lot numbers vary by compounding pharmacy
- Affected vials typically dispensed Q4 2025 through Q1 2026
- Patients receive recall notices directly from dispensing pharmacy when their lot is affected
What patients should do
- Check vial label against your dispensing pharmacy's published affected lot list
- Do not stop treatment without consulting your prescriber
- If affected, follow pharmacy instructions for replacement or return; bridge with branded if possible during gap
- Report any unexpected dose effects to prescriber and to FDA MedWatch
For clinicians
Review patient lot numbers at next visit; consider switch to branded semaglutide if compounded sourcing is in question; document lot tracking for any patient reporting dose-effect inconsistency.
