Recommended Storage for Zomacton
Zomacton (somatropin) vials and cartridges require refrigeration at 36°F to 46°F (2°C to 8°C). Do not freeze.[1]
Storing Before First Use
Keep unopened Zomacton in its original carton in the refrigerator. Avoid light exposure. Vials and cartridges remain stable until the expiration date if refrigerated properly.[1]
After First Use
- Vials: Refrigerate at 36°F to 46°F (2°C to 8°C) after reconstitution. Discard after 21 days or if solution is cloudy.
- Cartridges: Store in the refrigerator for up to 28 days after first insertion into the Zomactent needle-free device. Do not freeze or expose to heat above 86°F (30°C).[1]
What If Refrigeration Isn't Possible?
Do not store at room temperature (above 77°F or 25°C) for more than brief periods, like travel. Stability drops quickly outside 36°F to 46°F (2°C to 8°C). For extended power outages, consult a pharmacist—freezing ruins potency.[1]
Patient Tips for Compliance
Travelers use cooler bags with ice packs. Check solution clarity before each dose; discard if particles appear. Ferring Pharmaceuticals provides these guidelines in the prescribing information to maintain efficacy for growth hormone deficiency treatment.[1]
