What Do Doctors Do with the Remaining Botox when They Only Use 10-15 Units from a 50 Unit "Single-unit" Vial of Botox?

Botox comes in 50 unit and 200 unit vials.  If only 10 or 20 units are used from a 50 unit vial, the remainder is stored (refrigerated) for a few days. The product is removed with a new sterile needle each time so there is no risk of contamination.

Hi Plump.  As many of the other practitioners have explained, the use of a Botox for multiple patients is performed in a way as to keep the product sterile.  The most basic explanation is that the needles used to inject the Botox are not reinserted into the Botox vial once they have been used on a patient.  This ensures that the sealed vial remains sterile.

Botox does expire once it is mixed with saline and we usually use it within 1-2 days of mixing.  The manufacturer recommends that the product be thrown out 2 weeks after it is mixed with saline.  Check the link below regarding the Botox safety.

 

Botox comes in a 50 or 100U vial in the us.  It is mixed up with saline and drawn into syringes as it is used.  We never "re-load" a syringe that has been in the patient.  But one vial can treat more than one patent.  We buy the 100 U vials and get 2-3 patients out of it.
