Has anyone developed diabetes as a result of taking Prednisolone? I have GCA and PMR and started on 60mg of prednisolone on the 29th April 2015. I am now on my fourth attempt to get from 60mg down to 0. I controlled my diabetes by diet but this time my sugar level is out of control and my Dr want's me to start taking pills to control my sugar levels. What side effects has others had from taking pills?
