Pediatric GLP-1

GLP-1 medications in adolescents — what parents need to know

Wegovy is the first GLP-1 FDA-approved for adolescents with obesity (age 12+, BMI ≥95th percentile). This hub covers eligibility, family-conversation prep, and the open questions clinicians still flag.

Quick fact: In the STEP TEENS trial (NEJM 2022), adolescents on Wegovy 2.4 mg lost a mean 16% body weight at 68 weeks vs 0.6% on placebo.

Eligibility

Wegovy is approved for adolescents 12+ with BMI at or above the 95th percentile for age/sex (CDC growth charts). Zepbound is not yet approved for pediatric use. Tirzepatide adolescent trials are ongoing. Most pediatricians require documentation of prior lifestyle-intervention attempt and family engagement.

Family conversation

Pediatric obesity carries stigma; the conversation matters. Frame it as treating a chronic disease, not a willpower failure. Involve the adolescent in the decision. Pediatric obesity medicine specialists report higher long-term adherence when the teen agrees with the plan, not just the parent.

Open questions

Long-term safety data in growing bodies is the biggest unknown. The STEP TEENS trial was 68 weeks; what happens over 5-10 years is genuinely unclear. Bone density, growth velocity, and pubertal timing are being monitored in registry studies. The American Academy of Pediatrics 2023 obesity guideline supports pharmacotherapy at 12+ with appropriate monitoring.

Common questions

At what BMI percentile can my teen get Wegovy?

Wegovy is FDA-approved for adolescents 12+ with BMI at or above the 95th percentile for age and sex (per CDC growth charts). Some prescribers extend to the 85th percentile in the presence of weight-related comorbidities; that is closer to off-label and varies by clinic.

Is GLP-1 use in teens controversial?

It is debated. The American Academy of Pediatrics 2023 guideline endorses pharmacotherapy from age 12 for obesity. Critics flag long-term safety unknowns and the medicalization of normal childhood. The right answer depends on the individual teen, BMI trajectory, comorbidities, and family values.
