Please help! Tachycardia and scared. Can't sleep. 3 days after Botox

Tachycardia is not coming from the Botox most likely. You need to either go to the ER or follow up with your primary care doctor. It is very uncommon for this to be attributed to the Botox.

I am unaware of tachycardia resulting from Botox.  I recommend either seeing your primary care physician and/or going to a local ER to be evaluated.  Good luck!

Botox can migrate and cause distant side effects, which are usually rare. As far as the heart is concerned, cardiovascular side effects have included arrhythmia(tachycardia is an arrhythmia) and myocardial infarction(heart attack), some with fatal outcomes. Some patients had risk factors including cardiovascular disease. You should contact your PCP or, better yet, a cardiologist to discuss your concerns and have an examination.             jlr

This is not something I have ever encountered. If you are having rapid heart rate you should see your primary care doctor. An EKG might be warranted to ensure that your heart rhythm is normal. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

You are likely having a panic attack and can spare yourself a day in the ER and a huge medical bill if you can slow your thoughts, focus on your breathing and let go of fearful thoughts about your botox treatment. I promise you that botox does not cause a rapid heart rate but panic and guilt over it can. Please don't substitute my advice for that of your primary care physician but your symptoms are classic for hyperventilation and anxiety attack. It happens to strong people too and is just a shame when it leads to unnecessary medical treatment. This will go away when you relax, breathe and sleep.

Thank you for your question.Botox does not cause tachycardia. Never heard or read such a thing in the literature.Go to your doctor and get an ECG (EKG) and perhaps you need a Holter monitor and some type of cardiac stress testing.Best, Dr. Karamanoukian

I'm not sure this is from the Botox.  There are many possible side effects from these treatments, including those related to the injection itself (bleeding, bruising, swelling, etc) and from the neurotoxin (weakness of muscles aside from those that were targeted).  However, I am unaware of this as a typical reaction.I'd advise you to touch base with your plastic surgeon and with your internist for an assessment.Sorry but I hope that this helps and good luck,Dr. Alan EnglerMember of #RealSelf100@RealSelf
