I feel like I’m going to pass out when I have injections even though not painful. Why?

I have had several Juvederm and Botox injections. I do fine and it does not hurt, but when he is almost finished. I get very week almost pass out. I am having some more done Friday. Is there anyway I can prevent this? It does not hurt and I trust my doctor. They laugh at me and fan me and give me something to drink then I am ok. Why does this happen?

Oddly enough, it’s almost always young, healthy people with good hearts who have this problem with injections or blood draws. It’s called a vasovagal response and is fairly common.  It’s caused by the vagus nerve sending a signal to the heart to slow your heart rate, which drops your blood pressure making you feel faint/light headed.

There are several things you can do:

  • No coffee for 2-4 hours before injections

  • Stay very hydrated before

  • Eat a small meal about an hour before

Those strategies will help but are not perfect. Also, your doctor’s office really shouldn’t laugh (since patients can rarely pass out and fall or have a seizure). They should immediately put your head flat or inverted (trendelenberg), reassure you, and an ice bag on the back of the neck helps. You should sit up very gradually and allow your pressure to reequilibrate before standing up again. Food or juice also helps.

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes!
