What Dose of Zepbound is Most Effective

The 15 mg weekly dose of Zepbound (tirzepatide) is the most effective for weight loss in clinical trials. Studies show that patients taking the 15 mg dose lost an average of 22.5% of their body weight over 72 weeks, compared to 15% with the 10 mg dose and 9.5% with the 5 mg dose. However, many patients achieve significant results with lower doses while experiencing fewer side effects. The FDA-approved dosing schedule starts at 2.5 mg weekly and gradually increases every 4 weeks up to a maximum of 15 mg weekly. Your healthcare provider will determine the optimal dose based on your weight loss progress, tolerance to side effects, and individual medical factors.
