Determines age- and body weight-appropriate glucocorticoid dosage for pediatric patients with primary aldosteronism, particularly glucocorticoid-remediable aldosteronism (GRA), to avoid over-treatment. Use when prescribing glucocorticoids to children with confirmed or suspected PA; triggers include pediatric PA, GRA, or need to dose glucocorticoid based on age and weight.

# Calculate Glucocorticoid Dose for Children with PA
## STEP 1 — Gather Information
Collect patient age, weight (kg), and confirm diagnosis of PA or suspected GRA. Verify that glucocorticoid therapy is indicated (e.g., glucocorticoid-remediable aldosteronism). Obtain baseline BP and potassium.
## STEP 2 — Rule In / Rule Out
Is the patient a child (<18 years) with confirmed or suspected glucocorticoid-remediable aldosteronism (GRA) or PA requiring glucocorticoid? If yes, proceed; if no, do not use this skill.
## STEP 3 — Classify or Stratify
Determine appropriate glucocorticoid (e.g., dexamethasone or prednisone) starting dose based on age and weight: For dexamethasone, 0.125–0.25 mg/day; for prednisone, 2.5–5 mg/day, administered at bedtime. Adjust dose to lowest effective amount that normalizes BP and/or serum potassium.
## STEP 4 — Decide
Start with the lowest dose in the range, monitor BP and potassium, and titrate upward if needed to achieve normotension and normokalemia, avoiding signs of Cushingoid over-treatment. If BP fails to normalize with glucocorticoid alone, add an MR antagonist.
## Clinical Guardrails / Mimics / Pitfalls
Avoid overtreatment that can cause iatrogenic Cushing’s syndrome and impaired linear growth in children. Do not exceed doses needed to normalize BP/potassium. Monitor for growth retardation, weight gain, hyperglycemia, and hypertension relapse. Do not use in patients without PA/GRA.
## Concrete Clinical Example
A 10-year-old boy with hypertension and hypokalemia, diagnosed with GRA, weighs 30 kg. Start prednisone 2.5 mg at bedtime. After 2 weeks, BP 125/78 mm Hg, K+ 4.2 mmol/L; maintain dose. If BP remained 150/95, increase to 5 mg daily.
