(Source: PMC / JCI, 2026) Mental health monitoring: If you experience new or worsening depression, anxiety, or thoughts of self-harm while on or after stopping a GLP-1, contact your clinician promptly
Do not use semaglutide if you: Have a personal or family history of MTC or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
Global analyses similarly indicate that GLP-1 RAs remain substantially more accessible in diabetes care than in obesity care, reflecting reimbursement structures, variable professional familiarity, and weight-related biases in clinical pathways [88]
Cost-Effectiveness Analysis If tirzepatide produces 50% more weight loss than semaglutide (which clinical trials suggest), the cost per pound lost might actually be similar despite higher absolute cost: Semaglutide at $199: $96 per pound lost (based on trial averages) Tirzepatide at $349: potentially $105 per pound lost if weight loss is proportionally higher The medications are relatively comparable in cost-effectiveness, making the choice based more on individual response than pure cost considerations
