Quick answer: GLP-1 vs Contrave
GLP-1 medications (Wegovy, Zepbound) produce 2-3x more weight loss than Contrave (15-20% vs 5-8%). Contrave is an oral pill that targets brain reward pathways to reduce cravings, while GLP-1s are injectables that mimic hormones to suppress appetite and slow digestion. Contrave is cheaper ($100-200/month vs $1,000+), but telehealth compounded semaglutide has narrowed the cost gap. For most patients seeking significant weight loss, GLP-1s are the more effective choice.

How Contrave works
Contrave combines two medications:
- Naltrexone — opioid receptor antagonist that reduces reward from eating
- Bupropion — antidepressant that increases dopamine and norepinephrine
Together, they target the brain's mesolimbic reward system to reduce food cravings and appetite. Contrave is particularly effective for patients who struggle with emotional eating or food addiction.
Weight loss efficacy
- Wegovy (semaglutide) — 14.9% average weight loss (STEP 1 trial)
- Zepbound (tirzepatide) — 20.9% average weight loss (SURMOUNT-1 trial)
- Contrave — 5-8% average weight loss (COR trials)
GLP-1s produce roughly 2-3x more weight loss than Contrave. See How Much Weight on GLP-1s.
