    Allergic skin reaction to AntiBiotic
    Anon_54262 posted:
    After two weeks on Omnicef for a sinus infections, I developed an allergic rash to the med. Random rashes pop-up all over my body every 20-30 minutes, then go away after a while. Terrible itch. I stopped the AB five days ago, and was started on a 6-day pack of prednisone. Also taking benadryl 2x/day. The symptomns have not yet subsided, and are driving me crazy. Anyone else have this type of skin rash from an AB, and how long did it take to go away. I read that it can take several WEEKS to get the AB out of your system. Anything else I can do??? Help.
