It’s easier than you think, and this quick guide will help you avoid common mistakes and keep your treatment on track.

How to store and handle Tirzepatide properly

Storing Tirzepatide correctly is the first step in ensuring it works effectively. Keep the pen in the refrigerator between 36°F to 46°F (2°C to 8°C). Don’t freeze it. If it ever freezes, discard it. Also, never shake the pen. Please keep it away from heat and direct sunlight.
Once opened or removed from the refrigerator, it can be stored at room temperature—up to 86°F (30°C)—for approximately 21 to 28 days, depending on the brand. Always check the label. While traveling, carry it in a cooler or insulated bag. Safe handling ensures your medication remains effective and works as intended.

How Should You Store Tirzepatide?

Tirzepatide should always be stored in a refrigerator between 36°F and 46°F (2°C and 8°C). Keep it upright inside the original box to protect it from light. Never place it in the freezer. If it freezes, it must be discarded, even if it appears fine.
Always check the pen label for brand-specific instructions. For example, Mounjaro pens can be stored at room temperature for up to 21 days, but compounded versions may have different storage requirements. Make sure it’s not exposed to heat or sunlight.

What Happens If Tirzepatide Is Not Refrigerated?

If Tirzepatide is left outside the fridge for too long, it may lose its strength. High temperatures or direct sunlight can cause the medicine to break down slowly. This means it might not work properly, even if it looks normal. Using a weak dose may lead to poor blood sugar control or slow weight loss results.

Some versions, such as Mounjaro, can be stored at room temperature (below 86°F or 30°C) for up to 21 days. But if it’s left out too long or in a hot place like a car, it must be thrown away. Always check the time, temperature, and label before use.
