Health condition

Steroid-induced adrenal suppression

Long-term steroid treatment can switch off the body’s own cortisol production - which is why steroids must never be stopped abruptly, and why tapering plans matter.

Key points

What matters most, at a glance.

The essentials in plain English - symptoms, when to seek help, who to see and what treatment looks like.

  • Risk rises with more than 3-4 weeks of prednisolone above ~5 mg daily, but potent inhalers and creams can contribute

  • Never stop long-term steroids suddenly - withdrawal can trigger an adrenal crisis

  • Symptoms of suppression: fatigue, nausea, dizziness, aches and low mood as doses fall

  • Recovery of the adrenal axis after tapering can take weeks to many months

  • An endocrinologist can test recovery with morning cortisol or a Synacthen test and guide the taper

Understanding it

About Steroid-induced adrenal suppression, and what to do next.

Steroid medication does the adrenal glands’ job for them, and given long enough, the system that drives natural cortisol production goes dormant. If the tablets then stop suddenly, the body is left with no cortisol at all - risking an adrenal crisis during illness, injury or surgery. Suppression can also follow high-dose inhaled steroids, potent skin steroids over large areas, and repeated steroid injections.

The practical rules: taper rather than stop, carry a steroid card if you have been on significant doses, and increase doses during significant illness as advised. Where it is unclear whether the axis has recovered, a morning cortisol arranged by your GP settles it. Most people start with their GP, who can refer to an endocrinologist. NHS routine referrals often take 20-45+ weeks depending on where you live, while a private consultation is typically available within about two weeks.

    Severity varies from mild and self-limiting to more significant, depending on the underlying cause and how it's managed. A clinical assessment is the best way to understand what it means in your specific situation.

  • Is steroid-induced adrenal suppression hereditary or genetic?

    This depends on the specific condition — some cases have a genetic or familial component, while others are linked more to environmental, lifestyle or other health factors. If you have a relevant family history, it's worth mentioning to your clinician.
