Dysport - How long will tachycardia symptoms last?

I had 70 units of Dysport injected in my #11 and forehead one week ago. My symptoms include dry mouth (which has gone away) and tachycardia which I still have. How long should I expect these symptoms to last?

Possible side effects of Dysport

With cosmetic dosages of Dysport it is highly unlikely to develop systemic side effects such as tachycardia.  I would seek an evaluation with your primary medical doctor to rule out other possible causes of these symptoms.

70 units of Dysport is not a large dose.

There is no questions that botulinum toxin even is very small quantities is associated with a wide range of possible systemic reactions. There are rare but they can be alarming. There are just one or two reports of possible associated heart effects of botulinum toxin. They are so unusual that it is more probable than not that the "tachycardia" you are experiencing may not be related to your symptoms. I personally have seen an association between systemic side effects and a hyper-vigilance/mild panic state. Bottom line is that you should personally be assessed by your internist form this symptoms and not simply assume that they are related to your recent Botulinum toxin treatment.

Dysport side effects

Tachycardia is not a known side effect of Dysport as it doesn't have any adrenaline in it, which would affect your heart rate. If you are having this for any more than a few days I would suggest you see your physician. This is not a known side effect of Dysport and I wouldn't want to ignore it thinking it is.

Dysport side effects

The side effects you mention are not known to be caused by Dysport and are probably coincidental. Tachycardia, especially, would not be associated with botulinum toxin. I'd speak with your regular doctor and rule out other causes before blaming the Dysport.
