Unopened vials should be stored in a refrigerator (2 to 8°C). Do not use after the expiration date on the vial. After reconstitution BOTOX may be stored in a refrigerator (2 - 8°C) for up to 24 hours prior to use.
For safe disposal, unused vials should be reconstituted with a small amount of water then autoclaved. Any unused vials, syringes and spillages, etc., should be autoclaved, or the residual BOTOX inactivated using dilute hypochlorite solution (0.5%) for 5 minutes.
