GLP-1 expiration / Beyond-Use-Date tracker

When should I discard my GLP-1 vial or pen?

Enter your first-injection date and current storage condition. The tool returns your discard date and days remaining per the FDA-approved label for each brand-name product, plus the typical USP <797> conventions for compounded vials. Built on verbatim DailyMed citations — never use accessdata.fda.gov PDF URLs (they 404 silently when label revisions ship).

This is not medical advice. Storage rules are sourced from FDA-approved labels (DailyMed) for brand-name products and from USP <797> for compounded products. The Beyond-Use Date (BUD) printed on YOUR pharmacy label always wins — if it differs from the calculator's recommendation (especially for compounded products), defer to your pharmacy. If you're unsure whether your medication is still safe to use, contact your prescriber or pharmacist.

Frequently Asked Questions

Per the FDA-approved Wegovy label (DailyMed), Wegovy can be stored at temperatures up to 30°C (86°F) for up to 28 days after first use. Beyond 28 days at room temperature, discard the pen even if drug remains. Refrigerated storage (2-8°C / 36-46°F) is the default.

The FDA-approved labels list a 56-day in-use room-temperature period for Ozempic and a 28-day period for Wegovy. The two products have different formulation concentrations (Ozempic 1.34-2.68 mg/mL vs Wegovy higher-strength single-dose presentations) and the manufacturer ran different stability studies. The label is the authoritative source for each drug.

Both Mounjaro (DailyMed SetID d2d7da5d-ad07-4228-955f-cf7e355c8cc0) and Zepbound (DailyMed SetID 487cd7e7-434c-4925-99fa-aa80b1cc776b) are stable at temperatures up to 30°C (86°F) for 21 days. Beyond that, discard. Both labels were revised 4/2026.

Compounded products' Beyond-Use-Date (BUD) is set by the dispensing pharmacy per USP <797> conventions. Typical refrigerated BUDs for compounded semaglutide are 14-28 days, but the exact BUD depends on the pharmacy's documented stability validation for the specific formulation. Always defer to the BUD printed on YOUR vial label by the dispensing pharmacy. If your label and this calculator disagree, follow the pharmacy label.

If your pen was at temperatures above 30°C (86°F) for sustained periods (more than a few hours), the FDA-label storage conditions are violated and you should discard the pen and contact your pharmacy for a replacement. Brief exposure (e.g., a few minutes during transit) is generally acceptable per the FDA label, but use clinical judgment — when in doubt, contact your prescriber.

No. Oral tablets follow the printed expiration date on the bottle. There is no after-first-use clock the way there is for injectable products. Store oral GLP-1s at room temperature per their FDA-approved labels.
