What You Need to Know About GLP-1 Receptor Agonist Storage Instructions
Proper storage and handling are crucial for maintaining the potency and integrity of glucagon-like peptide-1 (GLP-1) receptor agonists, including semaglutide, dulaglutide, liraglutide, and tirzepatide.
Room Temperature vs. Refrigeration: What's the Difference?
The duration and conditions under which GLP-1 receptor agonists can be stored at room temperature vary between products. For example, Novo Nordisk GLP-1 RA products such as Ozempic, Rybelsus, Wegovy, Saxenda, and Victoza allow for specific periods of storage at room temperature after opening before use, according to their FDA labeling.
Storing GLP-1 Receptor Agonist Prefilled Pens:
- Unused pens should be stored in the original box in the medication fridge at 2 to 8o C until the manufacturer's expiry date.
Factors to Consider for Proper Storage:
- Medications like Ozempic, Wegovy, Mounjaro, Zepbound, Saxenda, and other GLP-1 receptor agonists should be refrigerated until first use. However, some products permit limited room temperature storage.

Beyond Standard Storage Guidelines:
- Some GLP-1 receptor agonists allow multi-dose pens to be stored at room temperature after opening.
Understanding proper storage and handling for GLP-1 receptor agonists ensures medication effectiveness while maintaining potency throughout its shelf life.
Labeling and Permitted Storage Periods:
Individual products' labels contain detailed information on storage requirements.
Why Are GLP-1 Receptor Agonist Storage Instructions Important?
Proper storage and handling of GLP-1 receptor agonists, including raglutide, dalglutide, liraglutide, and tirzepatide, are crucial for maintaining the potency and integrity of these medications. GLP-1 receptor agonists are sensitive to temperature and light, which can affect their stability and functionality.
Factors That Affect GLP-1 Receptor Agonist Storage:
- Temperature: GLP-1 receptor agonists must be stored at 2 to 8°C (36°F to 46°F) and protected from direct sunlight.
- Light: Exposure to light can degrade the medication.
- Humidity: Store the medication in a dry area, away from high humidity.
- Labeling: Follow the manufacturer's labeling instructions for specific storage requirements.
What Happens If I Don't Follow Glp-1 Receptor Agonist Storage Instructions?
Failure to store GLP-1 receptor agonists properly may result in: reduced potency, contamination, or expiration. This can lead to reduced efficacy, which can negatively impact health outcomes.
The Importance of Reading and Following Labeling:
When handling GLP-1 receptor agonists, it is essential to follow labeling instructions carefully. This includes storage conditions, expiration dates, and special handling instructions.
Proper Storage Considerations:
Home Storage:
- Choose a cool, dry area, like a refrigerator or a dark closet, to store GLP-1 receptor agonists.
- Keep the medication away from direct sunlight, heat sources, and moisture.
- Label the container or bag with the date and contents.
Traveling with GLP-1 Receptor Agonists:
- Use a cooler with ice packs to maintain a temperature between 2 and 8°C (36 and 46°F).
- Protect the medication from direct sunlight and extreme temperatures.
- Store the medication in the original container or a sealed bag.
Storage Considerations for GLP-1 Receptor Agonist Prefilled Pens:
- Unused pens should be stored in the original box in the medication fridge at 2 to 8°C until the manufacturer's expiry date.
By following proper storage guidelines and using the recommended storage containers and equipment, you can help ensure the efficacy and safety of your medication.
