Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I am in the throes of a niacin rash episode with the dreaded hives/rash reaction. I have had flushing from niacin numerous times over the 30+ year I have taken this vitamin...This episode beats them all , the hives are the size of pencil erasers and quite uncomfortable....how long do these last after the episode?
