Tirzepatide begins to work almost immediately after the first dose, with some biological effects starting within hours. Most people notice a reduction in appetite within the first 1 to 2 weeks, and measurable weight loss often begins around 4 to 8 weeks. Significant and consistent results, such as substantial weight loss and improved blood sugar control, typically become noticeable after 3 to 6 months of treatment, with continued progress possible up to a year or longer. The medication's full peak effect on blood sugar can take about 40 weeks. Individual response times can vary based on dosage, metabolism, lifestyle, and health conditions.
