I kept reconstituted botox in a freezer for about hour or two, then placed in refrigerator. Would it be still effective?

Thank you for the question. I agree with the answer below, if you are still uncertain about using the Botox after freezing it you can call Allergan for their best recommendation. Best Wishes,Pablo Prichard

The potency of Botox decreases approximately 10% if frozen after reconstitution. It can still be used, however, if this is kept in mind with regard to the doses used.
