If a Vial of Unmixed Botox is Left at Room Temperature (Not Frozen) Can It Still Be Used?

Depending on how long the vial was left out, it is likely that the product is still acceptable to use but it could reduce the efficacy of the treatment you are offering to paying clients. Much like expiry date on a product, it is still good, but the active ingredients may become left effective.

Contact the Allergan company to find out. They  have a most wonderfully supportive and academic science department. How many hours is satisfactory to be left at room temperature before dilution and storage, or restorage after delivery.  The Botox is shipped on dry ice to protect it during transportation. It normally is unpacked and placed in a freezer before mixing with sterlie saline.

It is against Allergan's recommendations to use Botox that has not been stored at the appropriate temperature.  You run the risk of delivering a treatment that may not be effective.  While it is likely that it would be fine, if a patient that is paying for their product, you want to insure that it is efficacious.
