Rapid Heartbeat, Anxiety and Tightness in Chest After Botox Injection, Is this Normal?

Rapid heart beat, tightness in the chest are not expected reactions after Botox injections.  There might be an allergic component in the Botox, although this is very very rare, or an ingredient in the liquid used to dilute it.  There might be an anxiety reaction but there is also a possibility that you are having a reaction to some liquid that was used to dilute the botox and that the liquid contained adrenaline (epinephrine). Epinephrine is not used in the approved diluent. If the doctor had used epinephrine, you should see an allergist to make sure you're not allergic to the botox and then see a new board-certified dermatologist or plastic surgeon for your next botox treatment.

After literally thousands of Botox injections over the last 10 years, I have never seen a rapid heart beat attributable to Botox.  I agree with others on this post that the signs and symptoms described are most likely related to anxiety.

The symptoms you describe are not related to the Botox itself but may be a reaction to the anxiety of the treatment. If you want to be treated again, you could limit the area and also request an anti anxiety medication prior to the injections. Best of luck.
