Zepbound is a weekly injection that helps with weight loss by controlling appetite. Proper storage keeps it effective and safe to use. Many people wonder about fridge life to avoid waste.
The main keyword, how long is Zepbound good for in fridge, comes down to official guidelines from Eli Lilly. Unopened, it lasts until the expiration date when refrigerated. This ensures the medication stays potent.
Following these rules helps you get the most from your treatment. Let’s explore the details on storage and handling.
Why Proper Storage Matters for Zepbound
Zepbound contains tirzepatide, a sensitive ingredient that can degrade with heat or light. Storing it wrong may reduce its power to help with weight loss. Fridge storage protects it best.
Heat breaks down proteins in the drug, making injections less effective. Cold spots can freeze it, which ruins the pen or vial. Always check for changes before use.
Good habits prevent costly replacements. Eli Lilly designs it for easy home use with clear rules.
Official Storage Guidelines from Eli Lilly
Eli Lilly recommends keeping unopened Zepbound in the fridge at 36°F to 46°F. This range, or 2°C to 8°C, keeps it stable until the expiration date on the box.
The expiration is usually about two years from manufacture. Check the label each time you refill. It applies to all doses from 2.5 mg to 15 mg.
Keep it in the original carton to block light. Light exposure can harm the solution over time.
Refrigerated Shelf Life: Unopened vs Opened
Unopened pens or vials last until expiration in the fridge. This gives months or years of usability if stored right.
Once opened, use it right away since it’s single-dose. No need to save leftovers—discard after injection.
For multi-dose options like some vials, follow pharmacy labels. But standard Zepbound is single-use.
Room Temperature Options and Limits
You can store unopened Zepbound at room temperature up to 86°F for 21 days. This works for short trips without a fridge.
After 21 days out, discard it. Don’t put it back in the fridge once warmed. This prevents moisture issues.
Track the date you take it out. Use a marker on the box to stay safe.
Signs Your Zepbound Is Still Good
Before each injection, inspect the solution. It should be clear and colorless with no particles. Cloudy or discolored means discard it.
Check the pen or vial for damage. Cracks or leaks make it unsafe.
If frozen, throw it away even if thawed. Freezing destroys the drug.
Best Practices for Fridge Storage
Place Zepbound on a middle shelf away from the door. Doors fluctuate in temperature. This keeps it steady.
Avoid the back wall or bottom—those spots get too cold. Use a fridge thermometer to confirm 40°F average.
Keep the carton closed. It shields from fridge light, which can fade the label.
Handling Temperature Excursions
If the fridge door stays open briefly, it’s often fine if cool to touch. But monitor for hours out.
Power outages count toward the 21-day room temp limit. Note the start time.

Traveling with Zepbound Safely
Pack in a cooler bag with ice packs for long trips. Avoid direct contact with ice to prevent freezing. Aim for under 86°F.
Airports allow it in carry-on. Declare at security and carry the prescription.
For vacations, plan fridge access. Hotels often have mini-fridges that work.
Differences Between Pens and Vials
Zepbound pens and vials follow the same fridge rules. Both last until expiration unopened at 36°F to 46°F.
Vials may need syringes, but storage stays identical. Single-dose means use once.
Some compounded versions differ—check labels. Stick to official for safety.

In rare cases, changes could cause irritation at injection site. Always inspect first.
Wasted doses add cost. Proper care saves money and effort.
Disposal of Expired or Used Zepbound
