I started taking this on October 8 for a sinus infection. by the 13th I was suffering intense headaches, nausea, fever of 102 and anxiousness. I thought that on top of my original ailment I also had the flu. After 2 doctors and a trip to the hospital in which no one thought of the side effects of this drug, and with the discovery of a full body rash 2 days ago, I finally called my pharmacist yesterday who told me to drop the drug. I then looked up everything I could find myself and this is obviously the result that so many people describe. I am now on benadryl and prednisone and still quite miserable. I think they should take this off the market since so many people have a bad reaction!!!!!!!!!!!
