Does Tirzepatide Need to Be Refrigerated? What the Label Says

What the Zepbound Label Says About Refrigeration

The Zepbound label calls for storage in a refrigerator at 2°C to 8°C (36°F to 46°F), with specific allowances for temporary room-temperature storage. The United States Food and Drug Administration (FDA) approved label instructs handlers never to freeze the product and never to administer medicine that has been frozen. The label instructs handlers to protect Zepbound from heat and light, and to store it in the original carton to protect from light.

Zepbound is supplied as a clear, colorless to slightly yellow solution in cartons containing four single-dose pens, single-dose vials, a multi-dose vial, or a single-patient-use KwikPen. For single-dose pens and single-dose vials, the label allows unrefrigerated storage at temperatures not exceeding 30°C (86°F) for a maximum total of 21 days. The label says to discard a single-dose pen or vial after a total of 21 days at room temperature.

Unopened multi-dose vials and single-patient-use KwikPens also require refrigeration at 2°C to 8°C, remaining usable until the printed expiration date if kept cold. When stored at room temperature up to 30°C, an unopened multi-dose vial or KwikPen must be discarded after 30 days. For additional details regarding device formats, review the guide on Zepbound vials vs pen options and the clinical summary explaining how tirzepatide works in the body.

Time Out of the Refrigerator by Zepbound Presentation

The length of time Zepbound may remain outside a refrigerator depends directly on the specific product presentation and whether the container has been opened. Single-dose presentations possess a shorter room-temperature window than multi-dose formats, and once opened, multi-dose devices carry additional discard criteria.

After opening, a multi-dose vial or KwikPen can be stored in the original carton in the refrigerator at 2°C to 8°C or kept at room temperature up to 30°C (86°F). The label says to throw away an opened device after a total of 30 days at room temperature, 30 days after first use, or after taking four weekly doses, even if medication remains inside the device.

What the Wegovy Label Says About Storage

Wegovy injection requires refrigeration at 2°C to 8°C (36°F to 46°F) before initial use, while oral Wegovy tablets require room-temperature storage protected from moisture. Injectable semaglutide must never be stored in a freezer or placed directly adjacent to the cooling element of a refrigerator. Like tirzepatide, Wegovy must never be frozen, and any pen that has frozen must not be used.

Injectable Wegovy single-dose pens and single-dose syringes require refrigeration, but before cap removal, each pen can be kept at 8°C to 30°C (46°F to 86°F) for up to 28 days. Once administered, the single-dose pen or syringe is discarded. For administration technique and rotation protocols, see the guide covering GLP-1 injection sites.The Wegovy FlexTouch single-patient-use pen follows separate guidelines. Before first use, the FlexTouch pen must stay refrigerated at 2°C to 8°C. After first use, it can remain stored for 56 days at 15°C to 30°C (59°F to 86°F) or inside a refrigerator at 2°C to 8°C. The pen cap must stay attached when not in use to protect from excessive heat and light. The FlexTouch pen must be stored without an injection needle attached, using a new needle for each injection and discarding that needle immediately after use.

Wegovy tablets follow an entirely different protocol. The tablets must be stored at 20°C to 25°C (68°F to 77°F), with temporary excursions permitted between 15°C and 30°C (59°F to 86°F). Tablets must remain in their original bottle in a dry place away from moisture.

Limits of the Storage Rules

Official storage instructions govern only FDA-approved manufacturer packaging and do not apply to compounded preparations or unauthorized formulations. The parameters described in the packaging insert for Zepbound and Wegovy apply strictly to the branded, factory-sealed products distributed in specified presentations. The label for a given product and presentation governs.

What to Look For in a Body-Composition Scale

A bioimpedance scale trends body fat and muscle rather than just weight — useful when the number stalls but your composition is improving. The absolute body-fat % isn't lab-accurate, so use it for TRENDS at a consistent time of day. Choose one that syncs to an app so you can watch the trend line.
