# Determine when to initiate pharmacotherapy for pediatric obesity

## STEP 1 — Gather Information
Collect patient age, BMI percentile, obesity status (BMI ≥95th percentile), details of any prior intensive lifestyle modification program (duration, components, adherence), weight change trajectory, and comorbidity profile (e.g., hypertension, dyslipidemia, NAFLD, PCOS).  

## STEP 2 — Rule In / Rule Out
If the patient is obese (BMI ≥95th percentile) and aged ≥2 years, proceed; otherwise, rule out pharmacotherapy (except consider only in clinical trial settings for overweight patients ≥16 years who are not obese).  

## STEP 3 — Classify or Stratify
If a documented formal program of intensive lifestyle modification has been attempted and failed to limit weight gain or improve comorbidities after an adequate trial, proceed to consider pharmacotherapy; otherwise, rule out pharmacotherapy and recommend intensifying or initiating lifestyle intervention.  

## STEP 4 — Decide
Initiate pharmacotherapy (e.g., orlistat) only as an adjunct to continued high-intensity lifestyle modification, under a clinician experienced in anti-obesity agents, with a plan to discontinue if there is <4% BMI/BMI z‑score reduction after 12 weeks at full dosage.  

## Clinical Guardrails / Mimics / Pitfalls
Do not use pharmacotherapy in overweight (BMI 85th–94th percentile) patients <16 years; avoid prescribing without concomitant lifestyle modification; monitor for gastrointestinal side effects (e.g., oily spotting with orlistat) and nutrient deficiencies; discontinue if inadequate weight response; ensure prescriber has expertise in anti-obesity agents and awareness of contraindications (e.g., chronic malabsorption for orlistat).  

## Concrete Clinical Example
A 14‑year‑old with BMI at the 98th percentile completes a 6‑month intensive lifestyle program (dietitian‑led meal planning, ≥60 min/day vigorous activity, behavioral counseling) with no BMI reduction and persistent hypertension; after documented lifestyle failure, the clinician discusses initiating orlistat with continued lifestyle modification and schedules a 12‑week follow‑up to assess ≥4% BMI reduction.
