Mounjaro is an effective weight loss treatment \u2013 but it\u2019s not right for everyone. Mounjaro price increases have left some patients concerned about the cost of the treatment. Others find the medication just doesn\u2019t agree with them.<\/p>\n\n\n\n
So, if you\u2019re on Mounjaro, you might be thinking about switching to Wegovy, another GLP-1 weight loss medication used for weight management. But how can you do this safely?<\/p>\n\n\n\n
Here, we explain what the process involves, with the help of our Lead Pharmacist Aamina Rafiq<\/strong>.<\/p>\n\n\n\n Wegovy<\/a> and Mounjaro are both weekly injections that work in similar ways. The active ingredient in Wegovy is semaglutide. However, Mounjaro contains tirzepatide.<\/p>\n\n\n\n Both medications are glucagon-like peptide-1 (GLP-1) receptor agonists. They mimic the hormone GLP-1, which sends messages to your brain to let you know you are full. They also slow down the rate food leaves your stomach. So you feel fuller quicker \u2013 and for longer.<\/p>\n\n\n\n However, Mounjaro is a dual agonist. This means it targets two hormones: GLP-1 and glucose-dependent insulinotropic polypeptide (GIP).<\/p>\n\n\n\n Because Mounjaro<\/a> is a dual agonist that also mimics GIP, some clinicians suspect that\u2019s why it can have a stronger effect. In clinical trials, patients lost an average of 22.5%<\/a> of their body weight after 72 weeks on Mounjaro. On Wegovy, patients lost an average of 16.9% after 68 weeks<\/a>.<\/p>\n\n\n\n The cost of Mounjaro is typically higher than Wegovy. Its manufacturer, Eli Lilly, increased its wholesale price in the UK<\/a> on 1 September, 2025. This meant every private provider in the UK had to raise their Mounjaro prices.<\/p>\n\n\n\nThe Difference Between Mounjaro and Wegovy<\/h2>\n\n\n\n
