In January, I went through the tiny yet dense red dots (went to drs and got antihistamines), then the clusters of red and normal skin patches in between and then things got better. They had me go off of all of my supplements, but it did take a full week after being seen for the itchy hives to go down. I suspect what caused the drug/allergic reaction was either Vitamin E or the blue dye in my bupropion tabs. Still don't know though. When you're on a ton of meds and supplements it's hard to tell, esp when you're starting and stopping things all the time. Stay in touch with your people, especially if things don't improve or get worse.
Hope you feel better soon.
