Question 1

Do I need to taper steroids after a 5-day burst?

Accepted Answer

Generally no. Short bursts (5–7 days) of prednisone or methylprednisolone for asthma or COPD exacerbations do not produce clinically significant HPA-axis suppression and can be stopped abruptly without a taper. Tapering becomes necessary when therapy exceeds about 2–3 weeks, particularly above 7.5 mg/day.

Question 2

What is a typical prednisone taper?

Accepted Answer

There is no universal schedule, but a common framework: above 40 mg, drop by 10 mg every step; 20–40 mg, drop by 5 mg; 10–20 mg, drop by 2.5 mg; 5–10 mg, drop by 1 mg; below 5 mg, drop by 0.5 mg. Each step lasts 1–2 weeks (faster for short courses, slower for long courses). The slow zone below 10 mg is the highest-risk part for both disease flare and adrenal insufficiency.

Question 3

When do I worry about HPA-axis suppression?

Accepted Answer

After more than 3 weeks of therapy at doses above 7.5 mg/day prednisone equivalent. With long-duration high-dose therapy (months at >20 mg), HPA recovery can take a year or more and some patients never fully recover. An 8 AM cortisol is a reasonable screen — > 10 µg/dL suggests intact axis, < 3 µg/dL suggests suppression, intermediate values warrant ACTH stimulation testing.

Question 4

What dose is "physiologic replacement"?

Accepted Answer

About 5 mg prednisone per day, or 15–25 mg hydrocortisone in divided doses, approximates normal endogenous cortisol production. Patients with persistent HPA suppression after long-duration therapy may need to remain at this dose until axis recovery, rather than tapering to zero.

Question 5

How fast should I taper for PMR or GCA?

Accepted Answer

In polymyalgia rheumatica, typical tapers begin at 15–25 mg/day and slow as the dose decreases — common pace is 12.5 mg → 10 mg → 9 mg → 8 mg over months, with relapse triggering re-escalation. In giant cell arteritis, starting doses are higher (40–60 mg) and tapers are slower, often over 1–2 years. Disease-activity recurrence is the trigger to step back up, not the schedule.

Question 6

Can I switch from prednisone to hydrocortisone for the taper?

Accepted Answer

You can, but it doesn't usually help. Hydrocortisone has a shorter half-life (8 hr vs 24 hr for prednisone), which can make symptom recurrence more obvious between doses. Most clinicians taper on the same agent the patient was already on. Equivalent doses: prednisone 5 mg ≈ hydrocortisone 20 mg.
