A patient calls the pharmacy expressing concern about a new prescription for 'prednisone 20 mg, take 1 tablet daily for 5 days, then 10 mg daily for 5 days, then discontinue.' They ask why the dose is being gradually reduced. What is the most appropriate explanation for this tapering schedule?
- ATo maximize the anti-inflammatory effect over a longer period.
- BTo prevent adrenal insufficiency and allow the body to resume natural cortisol production.
- CTo ensure the patient has enough medication to last until their next doctor's appointment.
- DTo reduce the risk of common side effects like stomach upset.
Show answer & explanationAnswer & explanation
Correct answer: B. To prevent adrenal insufficiency and allow the body to resume natural cortisol production.
Corticosteroids like prednisone can suppress the body's natural production of cortisol by the adrenal glands. A gradual tapering schedule allows the adrenal glands to slowly resume normal function, preventing adrenal insufficiency, which can be life-threatening.
Why the other options are wrong
- A. While prednisone has anti-inflammatory effects, tapering is primarily for safety, not to prolong efficacy.
- C. While medication supply is important, the primary reason for tapering is physiological, not logistical.
- D. Tapering might help manage some side effects, but the critical reason is to prevent adrenal crisis.
Corticosteroid Tapering
The gradual reduction of corticosteroid dosage over time to allow the adrenal glands to recover natural cortisol production and prevent adrenal insufficiency.
- Prevents potentially life-threatening adrenal crisis.
- Necessary when corticosteroids have been used for more than a few days.
- Patients should never abruptly stop corticosteroids without medical advice.
Memory trick: Don't 'Crash' your adrenals; 'Taper' your steroids to 'Recover' naturally.
