Can Botox Cause Loss of Smell and Taste?

As of this writing, I am unaware of these findings in the literature.  Botox is injected into the specific muscle.  Where it is commonly injected, loss of smell and taste should not be an issue.  

This is not an associated side effect of Botox. When injected properly by an experienced and board certified physician, Botox can yield a fantastic result and the chances of any negative side effects occurring are minimized. I hope this helps, and I wish you the best of luck.

For all side effects and adverse reactions to cosmetic Botox, I'd refer you to their website listed below. I haven't read nor heard of Botox causing loss of smell or taste.

Botox works on motor nerves (nerves responsible for movement) but not on sensory nerves, such as those for smell and taste.  So, there should be no loss of smell or taste after a Botox treatment.  

However it can cause an array of idiosyncratic reactions.  Loss of smell would be very unusual.  However I think you should bring your symptoms to the attention of your doctor.  This symptom warrants medical attention to determine the cause.

As far as we are aware, loss of taste and/or smell is not a side effect of Botox.  If the injection is administered properly, preferably by a Board Certified plastic surgeon, there should be very little in the way of side effects.  The most common side effect reported by my patients is mild headache the day of the injection; none have reported anything concerning loss of smell and/or taste. “Dr. D”

Usually botox does not affect anything else.  It should never affect smell or taste because botox only affects muscles.

Millions of patients have received Botox injections for cosmetic and therapeutic intent and I am not aware that it causes loss of taste and smell. You may want to contact Allergan and also talk to a neurologist to make sure that nothing else is going on with you,

I'm unsure if you are asking this question because this has happened to you, or because you are just curious. Neither of these is a listed side effect of Botox, nor is it present in literature, especially when it's used for cosmetic purposes in appropriate areas. If the Botox was injected into your nose or your mouth area, different side effects are possible, but when treating the forehead area, loss of taste or smell wouldn't be a known side effect.

I am unaware of this as being a side effect of Botox injections. My patients have never experienced any loss of smell or taste related to Botox injection.  Perhaps look on the manufacturers website for a list of all possible side effects. Best regards, Michael V. Elam, M.D.
