After I started Botox I experienced hearing loss in one ear and vertigo that comes and goes. Does Botox cause inner ear issues?

Hi. Thanks for asking the question. There is no known relation between botox injections, hearing loss and vertigo. You should be safe to get botox again. 
Good luck

Thanks for your question. At this time, there is no known relation between Botox and meniere’s or vertigo in general. I do think it’s safe to get Botox again. That being said, meneire’s disease can have various triggers, so if it happens again, I would avoid Botox. Good luck!

With something as serious as hearing loss and vertigo, you must have an MRI to rule out other, more serious problems such as an acoustic neuroma. Good luck from New York City
