Recommended Storage for Kevzara Prefilled Syringes
Store Kevzara (sarilumab) prefilled syringes in their original carton in a refrigerator at 36°F to 46°F (2°C to 8°C). Do not freeze or expose to freezing temperatures.[1]
What If Refrigeration Isn't Possible?
Kevzara syringes can be kept at room temperature up to 77°F (25°C) for up to 14 days. After that period, discard the syringe. Avoid direct sunlight or heat sources.[1]
Handling Before Injection
Remove the syringe from the refrigerator and let it sit for 30 minutes to reach room temperature before injecting. Do not use heat like microwaves or hot water to warm it. Inspect for damage or discoloration—do not use if particles are visible or the solution is cloudy.[1]
Travel and Portability Tips
Keep syringes in the original carton during travel to protect from light. Use a cooler pack for refrigeration if away from home, but ensure no freezing occurs. Patients report success with insulated bags for short trips, but always check temperature upon arrival.[1][2]
Common Mistakes to Avoid
Do not store near ice packs that could freeze the syringe, as this damages the medication. Avoid shaking the syringe, which can degrade the protein. If accidentally frozen, discard it.[1]
