I have a red rash on my chest just below my neck. It is bright red, kind of like when I use to take Niaspan and would have some red flushing. It started about three weeks ago. They changed my cholesterol a few months ago to Zocor. Could I be having a reaction to the meds. I had been taking Vytorin so I don t think it s the Zocor but I don t know.
Hi, I think the rash is a side effect of medication an allergic reaction to Color.  Maybe, you should stop using it or change for another brand.  Take any antihistamines such Ben Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further.
