Clinical trial data from the SURMOUNT program revealed that participants on tirzepatide (Mounjaro) experienced significant and sustained weight reduction over 72 weeks, with an average loss of up to 22.5% on the highest dose. However, for many patients, the initial rapid weight loss eventually slows or halts, leading to the common question: does Mounjaro stop working after a while? This period, known as a plateau, is a normal physiological response and does not mean the medication has failed.
