Why did I pass out immediately after Botox and Voluma?

You most likely fainted however you can never be too careful about your health. It would be worthwhile describing this to your primary care doctor and asking for their advice. However, you most likely had a vasovagal event during which your heart rate and blood pressure dropped. This usually happens during the injection but your scenario is not that unusual. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

This is common for some people as they get a "vasovagal" reaction where there heart rate goes really fast and they pass out.  I suggest a waiting period next time after you get injections before getting up and leaving, or taking a small amount of anxiety medication prior to injections.  Best, Dr. Emer.

Anxiety about your procedure can cause vasovagal reaction, which is a parasympathetic response, with fall in blood pressure, sweating, nausea, light headedness and sometimes frank passing out.  The good news is it is very short term. It is important for your doctor to be aware of the onset of the problem so you can be sited or laid back.  

 Thank you for your question, and sorry to hear about your experience. I would recommend that you go to a physicians office to have your future injections. They would be able to explain what is happening and help manage your symptoms.  a vasovagal response occurs when your blood pressure drops and there is less blood flow to the brain in response to an anxiety provoking experience.

You had was is known as a vasovagal response, a sudden drop in heart rate and blood pressure in response to a stressful trigger, like the sight of blood, a needle poke, or even an emotional situation. It's benign and is generally treated by resting supine, hydrating with water, etc. For the future, I recommend staying in the exam chair for a few minutes after your Botox and fillers before getting up. Also have something to eat prior to your procedure.
