There are two reasons for this. One of them is especially relevant at the beginning of the treatment, the other after a longer lasting therapy. Before we explain this, first of all the basic rule: always prefer a Cortisone therapy gradually and slowly reduce, so crawl, never abruptly stop.
Now for the explanations: If a cortisone treatment is prescribed for a rheumatic disease (but this also applies to other chronic immune diseases), then it is important at the beginning not to dose it too low. To effectively stop the inflammatory process, you start with high doses and then slowly lower the dose. If the dose is reduced too quickly, there is a risk of the inflammatory reaction flaring up again.
The body's own cortisone production has to start again
In a long-lasting cortisone treatment, the problem is another: The sustained supply of cortisone from the outside of the body's own cortisone production is further throttled. It takes a while to start up again after the treatment is over. So if you put the tablets too fast, would cause an acute cortisone deficiency. In extreme cases, this can be life-threatening.
Therefore, even with a sudden reluctance to use the cortisone treatment: Stay reasonable and slowly creep out!
