I know Botox caused tinnitus... how long will it last or is it permanent?

Headaches though uncommon have been reported with Botox and this typically last up to 2 weeks before they usually resolve spontaneously.  I have never seen tinnitus, however, in the 15 years of I have been injecting Botox (though anything is possible).  If you have the tinnitus for 2 weeks now, I would recommend that you see an ENT specialist to have this formally evaluated.

However, you should know that Botox is actually used to treat tinnitus.  Tinnitus is commonly associate with hearing loss.  It is far more likely that the tinnitus is not caused by botox.  If the botox did cause the tinnitus, we could advise you that like all botox related effects, it will wear off when the botox effects wear off.  It is far more likely that the two events (getting botox treatment and becoming aware of tinnitus are not related).  I recommend that you see your otolaryngologist or audiologist to be assessed for the tinnitus.

Botox doesn't effect the inner ear. If it persists, I recommend following up with your Doctor for a formal evaluation. Best, Dr. Emer
