How Long Does BETHKIS Last?

16.2 Storage and Handling BETHKIS should be stored under refrigeration at 2°C ‑ 8°C (36°F ‑ 46°F). Upon removal from the refrigerator, or if refrigeration is unavailable, BETHKIS pouches (opened or unopened) may be stored at room temperature [up to 25°C (77°F)] for up to 28 days. BETHKIS should not be used beyond the expiration date stamped on the ampule when stored under refrigeration 2°C ‑ 8°C (36°F ‑ 46°F) or beyond 28 days when stored at room temperature [up to 25°C (77°F)]. BETHKIS ampules should not be exposed to intense light. BETHKIS is light sensitive; unopened ampules should be returned to the foil pouch. The solution in the ampule is colorless to pale yellow, but may darken with age if not stored in the refrigerator; however, the color change does not indicate any change in the quality of the product as long as it is stored within the recommended storage conditions.
