If you got botox to the masseters, it is likely you got a dose of 20 to 30 units on each side. Although botox usually lasts 3-4 months in other areas of the face, I find botox at the higher doses in the masseters lasts approximately 6 months.
I would anticipate it wearing off...
Thank you for your question. As far as I'm aware, this medication will not negatively impact Botox. You can check with your treating physician for more information.
