A 38-year-old female with rheumatoid arthritis is being discharged with a new prescription for prednisone 20 mg daily. The nurse is providing medication education. Which statement is the most important for the nurse to include?

The most critical safety teaching for corticosteroid therapy is that abrupt discontinuation suppresses HPA axis function, leading to adrenal crisis — a life-threatening emergency with severe hypotension, electrolyte imbalance, and shock. This risk applies to anyone taking systemic corticosteroids for more than 1–2 weeks. Taking with food reduces GI irritation (correct but not the priority). Monitoring BP and glucose is important but secondary. Self-adjusting the dose is dangerous.

Clinical scenario

<span class="merci-scenario-label">Clinical Practice Guide</span><br>ACR 2022 RA Guidelines: any patient on systemic corticosteroids for ≥ 2 weeks should receive a written taper plan and explicit instruction never to stop abruptly.

Key concepts

• HPA Axis Suppression — Exogenous corticosteroids suppress endogenous cortisol production. Abrupt discontinuation after ≥ 1–2 weeks causes adrenal insufficiency. Symptoms: extreme fatigue, hypotension, hypoglycemia, shock.
• Adrenal Crisis — Life-threatening emergency from sudden cortisol deficiency. Symptoms: severe hypotension, nausea/vomiting, abdominal pain, fever, shock. Treatment: IV hydrocortisone immediately + IV fluid resuscitation.
• Cushing Syndrome (Iatrogenic) — Side effect of long-term corticosteroid use: moon face, buffalo hump, abdominal obesity, purple striae, osteoporosis, hyperglycemia, increased infection risk. NCLEX: Cushingoid features = suspect corticosteroid side effects first.
