Botox comes in one strength -- Botox single-use vials, containing 100 units of botulinum toxin type A. There are two forms of Botox: regular Botox and Botox Cosmetic. There is no difference between the two, except Botox Cosmetic is approved to treat wrinkles, while regular Botox is approved for the other uses.
Is There a Generic Version of Botox?
Currently, no generic versions of Botox are licensed for sale (see Generic Botox).
