Off-label
GLP-1 medications: off-label uses
Off-label use is legal in the US — clinicians can prescribe an FDA-approved drug for any condition they judge clinically appropriate. For GLP-1s, the most-discussed off-label uses are PCOS, NAFLD/MASH, addiction medicine, and pediatric BMI below the approved threshold.
Educational only. Off-label use should be discussed with a licensed clinician who can assess your individual risk-benefit profile.
PCOS
Polycystic ovary syndrome is the most-common off-label indication. Insulin resistance is the metabolic driver of PCOS in 60-70% of women; GLP-1s lower insulin and reduce androgens. A 2023 meta-analysis in Reproductive BioMedicine Online found semaglutide improved menstrual regularity and reduced free androgen index. Coverage: generally not insurance-covered as off-label.
NAFLD / MASH
Tirzepatide reduced hepatic fat content by ~30% in early MASH trials. The drug is not FDA-approved for MASH yet (Phase 3 trials ongoing), but liver-specialist prescribing for biopsy-confirmed MASH is increasingly common at academic centers.
Cardiovascular risk reduction
Wegovy is FDA-approved for MACE risk reduction in adults with cardiovascular disease and obesity (SELECT trial, 2023). For patients with cardio risk but BMI <30, off-label prescribing happens — usually after lifestyle and statin optimization. Insurance coverage requires the on-label criteria.
Addiction medicine
Observational data suggest GLP-1 use is associated with reduced alcohol intake and lower opioid-overdose rates. Mechanism likely involves dopamine reward signaling. Off-label prescribing for AUD or food addiction remains exploratory; randomized trials are early-stage.
Pediatric BMI
Wegovy is FDA-approved for adolescents 12+ with BMI ≥95th percentile. Off-label prescribing below age 12 or below the 95th percentile is uncommon and controversial. See /hub/pediatric-glp1.
Find a clinician who handles off-label
Most major telehealth providers prescribe on-label only. For off-label, an obesity- medicine specialist or academic-affiliated endocrinologist is usually the right call.
