I had similar experience while on KEVZARA. I was able to reduce prednisone rather quickly but It seemed as though while on KEVZARA I would get more of the infections that I had periodically gotten over the years. Getting cold sores were what I had most often while on kevzara. Ear and sinus infections were part of the mix. After a bout with diverticulitis I was put back on prednisone. I was on the injections for nine months.
