From the Research

To taper down from Zepbound (tirzepatide) when you reach your goal weight, work closely with your healthcare provider to develop a personalized plan, typically involving a gradual dose reduction rather than abrupt cessation, as evidenced by the latest studies on tirzepatide's effects on weight loss and metabolic parameters 1. When considering the tapering process, it's crucial to prioritize minimizing potential weight regain and withdrawal effects. The most recent and highest quality study, a systematic review and meta-analysis comparing tirzepatide and semaglutide, supports the efficacy of tirzepatide in weight loss, with a mean weight change of -11.4% compared to -7.3% for semaglutide 1. Key considerations for the tapering plan include:

  • Gradually reducing the dose, for example, stepping down from 15 mg weekly to 10 mg weekly for 4-8 weeks, then to 5 mg for another period, before potentially discontinuing the medication.
  • Solidifying lifestyle changes, including a sustainable diet and regular physical activity, which are crucial for maintaining weight loss.
  • Monitoring weight closely during the tapering process and reporting any significant weight regain to the healthcare provider, as this might indicate a need to adjust the tapering schedule or maintenance strategy. The importance of a personalized approach is highlighted by studies showing that tirzepatide can have significant effects on weight, lipid metabolism, and blood pressure in overweight/obese patients with type 2 diabetes mellitus 2, and its long-term use can result in sustained improvement in glucose control and cardiovascular biomarkers 3. However, the decision to taper should be made with caution, considering the potential for weight regain after cessation of therapy, as observed in a study where the investigator regained 5% body weight within two weeks after the conclusion of the study 4. Ultimately, the goal of the tapering process is to maintain the achieved weight loss while minimizing potential adverse effects, and this should be done under the guidance of a healthcare provider, taking into account the latest evidence and the individual patient's needs and response to treatment.
