When I picked up my first prescription of prednisolone I was given a printed schedule of when to reduce and by how much. Instructions were:
"Prednisolone 15mg orally, daily for 4 weeks; then reduce daily dose by 2.5mg every 4 weeks to 10mg daily; then reduce daily dose by 1mg every 4 to 8 weeks to stop."

I wanted to get off prednisolone sooner, so shortened the times between reductions, till at 8mg some pain came back. It was then I learned about prednisone withdrawal from decreasing too quickly, and how moving too quickly to get off it can be counterproductive because it can require an increase in dose to stabilise things. That can be time wasted and result in an overall increase in the cumulative amount taken. Slowly but surely is the way.
