NO, this temptation must be resisted by 2 rules:
First simple rule: never stop cortisone abruptly.
Second rule: do not consider that these treatments are harmless and increase, or decrease, the dose without medical advice.
Follow the medical prescription to the letter. If you feel the need to self-adjust, discuss the possibilities with your doctor: on the one hand, the dose flexibility (by how many milligrams of cortisone can you lower or increase yourself), on the other hand the rhythm (after how long you can change the dose).
