Botox: if one bottle of 100 units are diluted with saline could you get 400 units from a 100 unit bottle?

If one adds more saline, the volume drawn up into syringes is greater but the concentration of botox is less. Doctors use concentrations which work well for them. 1 unit/.01 ml, 1 unit /.02 ml, etc. but no one can create more number of units than 100 in a 100 unit vial.

Surgeons do vary the amount of diluent on occasion, but this will have no effect on the amount of botox present in the vial.

Hello, the saline required to reconstitute 100U of Botox will maintain the same 100U. It is not possible to get more Botox units than those listed on the package. 

No, adding saline does not increase the number of units.  Adding saline can; however, dilute the strength per injection.  It will never be more than 100 units!

Hi,If you had 100 apples in a barrel and then filled the barrel with any amount of water - how many apples would you have? The answer is always 100 apples. Mehdi Sina, MD

Thank you for your question. No, a vial of Botox that contains 100 units is only 100 units. To dilute the product saline is added and the amount that is added will determine how many units of Botox is delivered per cc or ml. I recommend having a consultation with an expert injector to address your concerns. Best of Luck!

The number of units will stay the same, only the concentration of it will be different by adding more saline.  Cheers!

Hi
I think we all wish that was true!
Unfortunately 100 units is 100 units. It comes in solid form and how much saline we use to reconstitute the units determines its concentration. 50 units with 1 cc will give 5 units per 0.1cc of solution.   If you use 1 cc or 3 cc and use it all that will be still 50 units.  As a physiatrist my first exposure to Botox was injecting larger muscles in legs and arms and we would use more saline so the dosage would spread to more area.  For the face we don’t want the medication spreading beyond a contained weal area to avoid unwanted results 
Thank you for the question 

A vial of botox that contains 100 units is only 100 units of botox.  Saline is added to dilute the product. The amount of saline that is added will determine how many units of botox is delivered per cc or ml of saline. The more saline that is added to the solution than more cc's  or  a larger amount of solution  is needed to deliver the same dose of botox.

Diluting the bottle with more saline will lower the concentration, but will not change the total number of units in the bottle.
