I am on Norco for chronic back and leg pain I had been taking a peach/pinkish pill but with my last shipment they switched to a white pill. I am having uticaria I saw a Derm and she stopped my Lipitor because I had just started on it the first of Sept. I'm on Zertec BIDand a cortisone cream. I' m still breaking out in hives. Could it be the change in Norco colors? I see my Derm this week.
