Contrave is NOT Appropriate for a Patient with BMI 24.37

Contrave is FDA-approved only for patients with BMI ≥30 kg/m² (obese) or BMI ≥27 kg/m² (overweight) with at least one weight-related comorbidity such as type 2 diabetes, hypertension, or dyslipidemia—a patient with BMI 24.37 falls below both thresholds and does not meet criteria for pharmacologic weight management. 1, 2

BMI Threshold Requirements

  • The FDA approval for naltrexone/bupropion ER (Contrave) specifically requires an initial BMI of ≥30 kg/m² OR a BMI of ≥27 kg/m² in the presence of at least one bodyweight-related comorbidity 2

  • A BMI of 24.37 is classified as normal weight (normal BMI range: 18.5-24.9 kg/m²), which is nearly 3 BMI points below even the lower threshold for overweight patients with comorbidities 1

  • All four pivotal Phase III clinical trials (COR-I, COR-II, COR-BMOD, and COR-DM) enrolled only patients meeting these BMI criteria, meaning there is no safety or efficacy data for patients with normal BMI 3

Clinical Context and Safety Considerations

  • Contrave was studied and approved as an adjunct to reduced-calorie diet and increased physical activity for chronic weight management in obesity, not for patients at normal weight 1, 2

  • The medication carries significant side effects including nausea (29.8%), constipation, headache, vomiting, dizziness, and dry mouth, with a black box warning for suicidal thoughts in young adults due to the bupropion component 1, 4

  • Using weight loss medications in patients who don't meet BMI criteria exposes them to unnecessary risks without established benefit and falls outside evidence-based practice 1

Common Pitfall to Avoid

  • Do not prescribe Contrave based solely on patient desire for weight loss or body image concerns when BMI is in the normal range—this represents inappropriate use of a medication designed for obesity management and could cause harm without proven benefit 1, 2

  • If the patient has specific concerns about food cravings or eating behaviors despite normal BMI, consider evaluation for eating disorders or referral to behavioral health rather than pharmacotherapy 4
