Rash - I have had a sinus infection since last November 2005. I had been prescribed Zithromax, Biaxin twice, Avelox, and then Omnicef in a 7-month period. The Omnicef, a 21-day dose, was prescribed in July 2006. Two days after I finished taking the Omnicef I began to get a rash. At first I thought it was bug bites because they were on my legs, arms and back. A week into it I realized these red bumps, that look like bug bites, were in fact more than a bug bite. I treated the bumps with Benadryl and Cortisone cream, the first week I had them, and instead of getting better the bumps were getting worse. I happen to go to my doctor about day seven of the rash for a scheduled check-up. I asked my doctor about the rash. She seemed concerned and prescribed a Methylpred Pak. The rash began to subside about four days into the Methylpred. By the end of the Methylpred the rash was about 95% gone. About three days after I completed The Methlpred the rash began to come back with a vengeance. I was actually worse that it was initially and was now spreading to my face. My doctor suggested I go to a dermatologist, which I did. The dermatologist said that I was having an allergic reaction to the Omnicef and that it was not that uncommon. He prescribed Prednisone. I took the Prednisone for 10 days and again the rash began to get better, but two weeks after I began the Prednisone the rash still was not gone. The dermatologist again gave me More Prednisone to take, but not as much as the first dose, to get rid of the rash. The rash almost went away with the exception of a couple of bumps. This was as of 9/15/06. Today is 9/30/06 and as I write this, my back is once again covered in the rash. I am now starting to get it on my lags and arms again as well. Bah! I started taking a Methylpred Pak again this morning. This will make the third time since mid-April. I remain hopeful that this terrible rash will clear up, as it is uncomfortable and cause for great distress.
