How to Taper Off Cortisone: Why You Must Never Simply Stop Prednisolone
Cortisone is one of the most powerful — and most feared — medications. The long list of side effects tempts many people to stop it as quickly as possible. Understandable — but dangerous. Stopping cortisone abruptly can be worse than the side effects themselves.
EMERGENCY: Addisonian crisis → call 112 immediately!
If you experience a severe drop in blood pressure, circulatory collapse, confusion, or vomiting after stopping cortisone, call emergency services immediately — possible adrenal crisis.
The Mechanism: Why the Adrenal Glands Need Time
Your body naturally produces approximately 5–7 mg of cortisol per day (equivalent to around 5 mg prednisolone). Production is regulated through a feedback loop:
🧠 The HPA Axis (Hypothalamic-Pituitary-Adrenal Axis)
When you take prednisolone, the brain registers: "Enough cortisol" — and dials down its own production. With prolonged use, the adrenal cortex can actually shrink (atrophy). It needs weeks to months to resume full function.
The Cushing threshold: this is where it gets critical
From approximately 7.5 mg prednisolone per day, the body's own cortisol production is suppressed. Below this threshold, the risk is low. Evening doses suppress production more strongly than morning doses — this is why cortisone should always be taken in the morning, unless your doctor instructs otherwise.

A Concrete Tapering Schedule for Prednisolone
This is a general guide — your doctor will adjust it individually:
Phase 1
> 20 mg → 10 mg
Rapid reduction
Reduce by 5–10 mg every 1–2 weeks. At these levels the adrenal glands are already strongly suppressed — larger steps are still possible here. Still far from the physiological zone.
Phase 2
10 mg → 5 mg
Moderate reduction
Reduce by 2.5 mg every 1–2 weeks. Approaching the physiological dose — proceed with more care. The adrenal glands must increasingly contribute on their own.
Phase 3
5 mg → 0 mg
⚠ Critical zone
Reduce by 1 mg every 1–2 weeks — or even 0.5 mg. The most challenging phase. The adrenal glands must now produce independently. After long-term therapy, this phase can take months.
Reduced too quickly? Return to the last well-tolerated dose
If you develop symptoms during tapering: don't continue. Return to the last dose that felt manageable — then work with your doctor on a slower plan.
As long as the adrenal glands are recovering, they cannot respond adequately to acute stress (fever, surgery, an accident, infection) — in these situations the body needs significantly more cortisol.
General rule for the transition period:
With fever > 38.5°C (101.3°F), vomiting/diarrhoea, or a planned operation: temporarily increase the cortisone dose (following your doctor's instructions). This rule applies during tapering and for up to 12 months after stopping a long-term cortisone therapy. Some patients receive a steroid emergency card documenting that they require cortisol in an emergency.
Local Cortisone: Spray, Cream, Injection — Do I Need to Taper Those Too?
Nasal spray / inhaler
No tapering needed
Systemic absorption is minimal. However: never stop asthma inhalers without consulting your doctor — your asthma would then be uncontrolled.
Cortisone cream
Tapering rarely needed
Minimal systemic effect. Exception: very large-area, long-term use of potent preparations.
Joint injection (single)
No tapering needed
A single intra-articular injection has minimal impact on the adrenal glands.
Depot injection (intramuscular)
Caution — ask your doctor
Can suppress the adrenal glands more than tablets, as it maintains a consistently elevated level over a longer period. Inform your doctor.
Frequently Asked Questions About Stopping Cortisone
If taken for more than 2 weeks at doses above 7.5 mg prednisolone per day, tapering is recommended. Short burst courses (e.g. 5 days for an asthma attack) can usually be stopped directly — always speak with your doctor first.
Muscle pain, fatigue, and flu-like symptoms indicate the body is readjusting — unpleasant, but temporary. If symptoms are very severe: return to the last well-tolerated dose and taper more slowly.
Acute cortisol deficiency with a severe drop in blood pressure, circulatory failure, and confusion — life-threatening. It can occur when cortisone is stopped abruptly after long-term therapy. In an emergency, call 112 immediately.
This varies greatly between individuals. After short-term therapy: days to weeks. After long-term therapy: months, sometimes up to a year. During this time, adrenal function must be monitored by a doctor (ACTH stimulation test).
Generally not. Topical applications on the skin have minimal systemic effects. Exception: very large-area, long-term use of potent cortisone preparations.
No — not because of the adrenal glands (inhaled preparations have minimal systemic effect), but because your asthma would then be uncontrolled. Never change your asthma therapy without consulting your doctor.
Support dose changes during tapering safely
When tapering cortisone, the dose changes constantly. brite always reminds you of the current daily dose — and documents every step for your next doctor's appointment.
