How long can Botox be used after it has been reconstituted?
- 7 years ago
I was recently told that Botox does not need to be used right away after being reconstituted and that it can be kept in the refrigerator for "X" amount of time. I was injected recently with the same # of units as usual. (new clinician this time) The botox was not as efeective initially and now wearing off after less than 2 1/2 months. In previous injections it lasted at least 3 months or even 4 months. I wonder if it was "old" Botox this last time?
