I find that when I do injectable fillers, such as Juvederm, Radiesse and Artefill I occasionally have patients who faint or nearly faint. It is common but we do our best to try to prevent it if possible. Before I treat a patient for the first time with a filler I usually ask them if they have ever fainted or gotten light-headed in the past with medical procedures or blood tests. If a patient says “yes” we put their feet up and recline them slightly, which usually prevents the problem from occurring. After treating hundreds of patients with fillers, I have discovered an interesting correlation with other answers to my question. If they give me an immediate, firm “no”, sometimes with a small laugh (as if to say, “me, are you kidding!?”), I know they will be fine and rarely will they become light-headed or faint. If however they hesitate in the least when answering my question, or answer “not really”, 9 times out of 10 they will get light-headed, usually when we are almost done with this quick 10 minute procedure. This was proven to me once again this week and I have decided that “not really” actually means, “I don’t want to, I will try my best not to, I am hoping I won’t, but I will DEFINITELY get light-headed after you start to inject me, whether I think I will or not.”
So, if you aren’t 99% - 100% sure you won’t faint or get light-headed, don’t be embarrassed about it. Tell your doctor. A caring physician will take special care to help you avoid this.
