Should steroids be stopped immediately or tapered in cases of delirium (confusional state) caused by steroid (corticosteroid) use?

Management of Steroid-Induced Delirium: Taper vs. Immediate Discontinuation

Steroids should generally be tapered rather than stopped abruptly when delirium occurs, though the decision depends on the duration of therapy, dose, and clinical urgency—patients on short courses (<14 days) or low doses may tolerate abrupt discontinuation, while those on prolonged therapy require tapering to prevent adrenal insufficiency and withdrawal symptoms. 1, 2, 3

Clinical Decision Framework

When to Consider Abrupt Discontinuation

• Short-duration therapy (<14 days): Patients receiving steroids for less than 2 weeks have minimal risk of adrenal suppression and may tolerate immediate cessation 1
• Low-dose regimens: Doses equivalent to <15 mg prednisone daily carry lower risk of withdrawal complications 4
• Severe, life-threatening delirium: When psychiatric manifestations pose immediate danger (severe agitation, psychosis, violent behavior), the urgency may warrant rapid discontinuation with close monitoring 5, 6

When Tapering is Mandatory

• Prolonged therapy (>14 days): Corticosteroid-induced adrenal suppression is duration-dependent, making patients particularly likely to benefit from tapering before discontinuation 1
• High-dose therapy: Patients receiving doses >200-300 mg/day hydrocortisone equivalent require gradual dose reduction 1
• Critical illness context: In sepsis or other severe conditions where steroids are treating the underlying disease, abrupt cessation risks disease recurrence and adrenal crisis 1

Evidence-Based Tapering Approach

The BMJ sepsis guideline explicitly states that whether corticosteroids should be tapered rather than stopped abruptly is unclear, but notes that patients receiving longer courses (>14 days) are particularly likely to benefit from tapering and evaluation of hypothalamo-pituitary-adrenal axis function. 1

Practical Tapering Strategy

• Monitor carefully after any dose reduction or discontinuation: Inflammation may recur after stopping corticosteroid therapy, especially when stopped abruptly 1
• Watch for withdrawal syndrome: Following prolonged therapy, withdrawal may cause fever, myalgia, arthralgia, and malaise—this can occur even without adrenal insufficiency 2, 3
• Consider reinitiation if deterioration occurs: In patients who worsen after stopping (development of shock, need for mechanical ventilation), restarting corticosteroids could be helpful 1

Management of the Delirium Itself

Immediate Non-Pharmacological Interventions

• Implement environmental modifications first: Provide adequate lighting, clear signage, visible clocks and calendars for orientation 7
• Facilitate family presence: Regular visits from familiar people help with patient reorientation 7
• Ensure basic physiological needs: Adequate hydration and prevention of constipation 7

Pharmacological Management

• For moderate delirium: Consider oral haloperidol, risperidone, olanzapine, or quetiapine 7
• For severe delirium with agitation: Use antipsychotic medications such as haloperidol, olanzapine, or chlorpromazine 7
• Avoid benzodiazepines: Do not use as initial treatment unless the patient is already taking them or experiencing alcohol withdrawal 7
• Case report evidence: A 33-year-old with steroid-induced delirium responded to haloperidol 7.5 mg and quetiapine 700 mg daily 5

Critical Monitoring Parameters

During Steroid Reduction

• Watch for adrenal insufficiency signs: Hypotension, hypoglycemia, hyponatremia, hyperkalemia 1, 2
• Monitor for disease recurrence: The underlying condition being treated may flare 1
• Assess for withdrawal symptoms: Myalgia, arthralgia, malaise, fever 2, 3

During Delirium Management

• Serial neurologic evaluation: Assess cognition and motor function at least twice daily 1
• Laboratory monitoring: CRP, ferritin, CBC, comprehensive metabolic panel 1
• Reassess medication need regularly: Antipsychotics should be reevaluated frequently and discontinued when no longer needed 7

Common Clinical Pitfalls

The most dangerous error is overlooking hypoactive delirium, which is often underdiagnosed but is the most prevalent subtype in palliative care patients. 7 This is particularly relevant because steroid-induced delirium can present as mixed type with fluctuating features. 7

Additional Cautions

• Don't ignore the dose-response relationship: Steroid psychosis manifestation is dose-dependent, requiring particular caution in elderly patients 6
• Recognize vulnerable populations: A 91-year-old man developed severe delirium from just 15 mg prednisone, illustrating that even low doses can trigger delirium in vulnerable elderly patients 4
• Consider the clinical context: In brain metastases, the guideline specifically states that corticosteroid therapy duration should be minimized and "generally should be tapered rather than abruptly discontinued given the gradual improvement of edema with oncologic therapy and the potential for adrenal insufficiency" 1

Special Considerations by Clinical Context

Sepsis Patients

• Typical hydrocortisone dose is 200-300 mg/day for 7-14 days or less for those rapidly improving 1
• Careful monitoring after discontinuation is essential as inflammation may recur 1

Brain Metastases

• Dexamethasone is preferred given its relative lack of mineralocorticoid activity 1
• Duration should be minimized to prevent long-term sequelae including personality changes, suppressed immunity, metabolic derangements, insomnia, and impaired wound healing 1

ICU Patients

• Evidence on corticosteroids and delirium is mixed—some studies suggest increased risk while others show no difference or even protective effects 1
• One recent study found hydrocortisone reduced delirium incidence by half in sepsis patients 1
