This creates a paradox for payer economics—the "inflationary chronic use" concern assumes sustained adherence, but the actual problem is insufficient persistence. Under capitation, payers pay for 12 months of therapy ($2,940 at $245/month) for patients who discontinue and regain weight, capturing net cost with no downstream savings from avoided complications. The economics only work if adherence is sustained AND the payer captures downstream benefits—with 85% discontinuing by two years, the downstream cardiovascular and metabolic savings that justify the cost never materialize for most patients.
