Safe Cessation of Corticosteroids

Criteria for Safe Abrupt Cessation

For asthma exacerbations treated with systemic corticosteroids for 5-10 days, there is no need for gradual reduction, especially if the patient is using concurrent inhaled corticosteroids, as recommended by the American Academy of Allergy, Asthma, and Immunology 1
The FDA label for prednisone indicates that "for courses of less than 1 week, there is no need to taper the dose", according to the American College of Clinical Pharmacology 1

Physiologic or low doses (<10 mg/day of prednisone equivalent) used for short periods can be stopped abruptly without significant risk, as stated by the European Society for Medical Oncology 2, 3

For prolonged treatments, the reduction should be done over at least 1 month, as recommended by the European Society for Medical Oncology 2
In immunotherapy-related toxicities, corticosteroid reduction should be done gradually over 4-6 weeks, according to the National Comprehensive Cancer Network 4, 3

Oncologic immunotherapy can only be resumed when corticosteroids have been reduced to ≤10 mg/day of prednisone or equivalent, as stated by the European Society for Medical Oncology 2, 3
The reduction should not be too rapid to avoid recurrence or worsening of immune-related adverse events, as recommended by the European Society for Medical Oncology 2

Endocrinopathies controlled with hormone replacement therapy do not require permanent suspension of immunotherapy, even if they are grade 4, as stated by the European Society for Medical Oncology 2
For checkpoint inhibitor-related colitis, a shorter reduction may help minimize infectious complications, as long as the colitis does not worsen during reduction, according to the National Comprehensive Cancer Network 4

Multiple clinical trials using dexamethasone 40 mg for 4-5 days in conditions like ITP and Bell's palsy stopped the medication abruptly without tapering, demonstrating the safety of this approach 5, 6
The American Academy of Otolaryngology-Head and Neck Surgery guidelines support the use of prednisolone 60 mg for 5 days with a 5-day taper or 50 mg for 10 days without specifying mandatory tapering for the shorter course, indicating flexibility in short-course management 6

High-quality evidence from studies on COPD exacerbations shows that 5-day courses of systemic corticosteroids are equivalent to 10-14 day courses, with no difference in treatment failure or relapse rates, and these studies routinely stopped corticosteroids abruptly after 5 days without adverse effects 5, 6
