Can Botox Affect my Sleep Apnea?

To my knowledge, Botox would not treat sleep apnea nor would cosmetic use of Botox have any implications for this condition.

There should be no exacerbation or improvement in your sleep apnea if you have upper forehead, glabellar frown lines or crow's feet treated with Botox. If however, you have a high number of units injected into the neck for platysma bands or horizontal neck creases (the latter in my hands don't improve with Botox), there might be a diffusion to affect your sleep apnea, but this is not well reported.

Hello Sandra.  As long as the Botox you are getting is injected into the upper face, then there will be no affect on your sleep apnea.  

Botos is sometimes injected into the neck wrinkles (platysmal bands). As long as the Botox is not injected into this area, you should be ok.
