Does Botox expire? We have had the same unmixed (no solution) vial for almost 6 months.

Of course it can expire,simply read the label should be right there unless you got some suspect"non Allergan" product

I'm sorry...but as an injector you should know the answer to this! Botox vials are labeled on the side of the box and the vial itself with an expiration date. This expiration date is for pre-constitution. "This answer has been solicited without seeing this patient and
