Eventually, this may cause the body to temporarily lose the ability to manufacture natural corticosteroids (especially cortisol), which results in dependence on prednisone. For this reason, prednisone should not be abruptly stopped if taken for more than seven days; instead, the dosage should be gradually reduced. This weaning process may be over a few days if the course of prednisone was short but may take weeks or months{{Cite news |url=https://www.medicinenet.com/steroid_withdrawal/article.htm |title=Steroid Drug Withdrawal Symptoms, Treatment & Prognosis |work=MedicineNet |access-date=14 June 2018 }} if the patient had been on long-term treatment.

For this reason, glucocorticoid analogue drugs such as prednisone down-regulate the natural synthesis of glucocorticoids. This mechanism leads to dependence in a short time and can be dangerous if medications are withdrawn too quickly. The body must have time to begin synthesis of CRH and ACTH and for the adrenal glands to begin functioning normally again. [194] => [195] => Prednisone may start to result in the suppression of the [[Hypothalamic–pituitary–adrenal axis|hypothalamic–pituitary–adrenal (HPA) axis]] if used at doses 7–10 mg or higher for several weeks. This is approximately equal to the amount of endogenous cortisol produced by the body every day. As such, the HPA axis starts to become suppressed and [[atrophy]]. If this occurs the patient should be tapered off prednisone slowly to give the adrenal gland enough time to regain its function and endogenous production of steroids. [196] => [197] => === Withdrawal === [198] => The magnitude and speed of dose reduction in corticosteroid withdrawal should be determined on a case-by-case basis, taking into consideration the underlying condition being treated, and individual patient factors such as the likelihood of relapse and the duration of corticosteroid treatment. Gradual withdrawal of systemic corticosteroids should be considered in those whose disease is unlikely to relapse and have: [199] => [200] => * received more than 40 mg prednisone (or equivalent) daily for more than one week [201] => * been given repeat doses in the evening [202] => * received more than three weeks of treatment [203] => * recently received repeated courses (particularly if taken for longer than three weeks) [204] => * taken a short course within one year of stopping long-term therapy [205] => * other possible causes of adrenal suppression [206] => [207] => Systemic corticosteroids may be stopped abruptly in those whose disease is unlikely to relapse and who have received treatment for three weeks or less and who are not included in the patient groups described above. [208] => [209] => During corticosteroid withdrawal, the dose may be reduced rapidly down to physiological doses (equivalent to prednisolone 7.5 mg daily) and then reduced more slowly.
