I'm Having Difficulty Swallowing Within Minutes After Botox Injections.

Hi Regan.  Although we have never had a patient report the same experience, difficulty swallowing is a potential side effect of using Botox.  

This potential side effect is much more likely if you are having the neck wrinkles (bands) injected or if the product is being used for medicinal rather than cosmetic purposes.  

You should address it with both your GP and your injector before considering moving forward with treatment again. 

Trouble breathing occurs due to the weakening of associated muscles, although it is more common when treating the neck bands. If you experience this, please stop getting Botox for your safety. This is a dangerous complication. It is difficult to say why you have developed a reaction after so many years, however you should have this checked out. Best of luck.

This is an extremely rare side effect. You need to bring it up to your physician who should notify Allergan, the company that makes the Botox.  Could it be that some Botox got into a blood vessel and it is causing a distant effect on the swallowing muscles?  Another possibility is that you are reacting to an ingredient in the liquid used to mix the Botox powder in the vial prior to injecting it. you may need to see an allergist after speaking to the doctor who did your botox.  They may need to supply you with some of the liquid diluent for the allergist to test.  There might be some preservatives in the diluent to which you have become sensitized, or even the Botox itself, but again, this is extremely rare.
