I started taking this drug on 1/14/09. On 1/21/09, I started breaking out in hives. By 10pm that night, I felt like I had rolled around in attic insulation. It felt like I had tiny pins and needles sticking me everywhere! ... it was awful!! - I was given this drug to treat an ear infection. I'm now on prednisone (50 mg for several days, and then tapering off). I'm now wondering if my ENT doctor is a goof?
