Can Gvoke Be Kept at Room Temperature?
Yes, Gvoke (glucagon injection) can be stored at room temperature for limited periods, but refrigeration is required for long-term stability. Unopened Gvoke syringes or vials should be kept refrigerated at 36°F to 46°F (2°C to 8°C). Once removed from the refrigerator, they remain stable at room temperature up to 77°F (25°C) for up to 12 months or until the expiration date, whichever comes first.[1][2]
How Long Can It Stay Out of the Fridge?
Gvoke is designed for convenience during emergencies like severe hypoglycemia. An unopened device can be kept at controlled room temperature (59°F to 77°F or 15°C to 25°C) for 12 months total across multiple periods, as long as it doesn't exceed the expiration date. Avoid extreme heat, freezing, or direct sunlight—exposure beyond these limits can degrade the medication.[1][2]
What Happens If It Gets Too Hot or Frozen?
If Gvoke freezes, thaws it slowly at room temperature and inspect for damage before use; discard if particles appear or it's discolored. Heat exposure above 77°F shortens shelf life—do not use if it's been stored above 86°F (30°C) for extended time. Always check the clear liquid for cloudiness or discoloration prior to injection.[1]
Storage Tips for Travel or Daily Use
For portability, keep Gvoke in a cooler bag with an ice pack during travel, but allow it to reach room temperature before injecting. Once opened, use immediately—do not store partial doses. Patients often carry it in a purse or glove compartment, relying on the 12-month room-temp allowance to avoid constant refrigeration.[2][3]
Differences Between Gvoke HypoPen and Syringe
Both the prefilled syringe and HypoPen follow the same rules: refrigerate until needed, then up to 12 months at room temp. The HypoPen's single-use design makes it popular for school or work settings where refrigeration isn't practical.[1][2]
