Tirzepatide (5, 10, and 15 mg) achieves stringent glycemic (HbA1c < 5.7% or ≤ 6.5%) and weight loss (≥ 10% or ≥ 15%) targets with a statistically significantly lower cost per responder and lower number needed to treat (NNT) compared to semaglutide 1 mg in patients with type 2 diabetes.

If you have Type 2 Diabetes and are struggling to reach strict blood sugar (HbA1c < 5.7% or ≤ 6.5%) or significant weight loss goals (≥ 10-15%) with metformin, switching to or starting tirzepatide (5-15 mg weekly) is likely more effective and cost-efficient for achieving those specific targets than using semaglutide 1 mg. While tirzepatide has a higher yearly drug price, you are more likely to succeed with it, making it 'cheaper' per successful outcome.

GoodSupportsHIGH confidence
All doses of tirzepatide across composite endpoints (HbA1c < 7.0%, ≤ 6.5%, or < 5.7%/weight loss ≥ 10%/no hypoglycemia) had statistically significantly lower costs per responder and NNTs than semaglutide 1 mg, demonstrating that tirzepatide provides better value for achieving lower HbA1c thresholds and weight loss goals without increasing the risk of hypoglycemia.

Why this rating

Based on a phase 3 randomized clinical trial (SURPASS-2) with a large sample size (n=1,879), though the analysis is a short-term (1-year) economic model rather than long-term clinical outcomes.
