Is Mounjaro Worth It? A Cost-Benefit Check

So, everyone’s talking about new meds like Mounjaro (tirzepatide) for obesity and related issues. It was first made for type 2 diabetes, but now it’s making waves for weight loss and fixing metabolic stuff (MCLAUGHLIN; WADDEN, 2024, p. 15). It’s popular but pricey. Is it really worth the cash? Let’s take a closer look.

Mounjaro works by targeting two hormones, GLP-1 and GIP, to curb your appetite, help you lose weight, and control blood sugar (MCLAUGHLIN; WADDEN, 2024, p. 18). A study called SURMOUNT-1 showed it can lead to way better weight loss than a fake pill, with about 88% of people losing over 5% of their starting weight, and some losing over 20% at certain doses (AP News, 2023). Sounds amazing, right? But how well it works isn’t the only thing that matters when you’re figuring out if it’s worth the cost.

Here’s the kicker: Mounjaro ain’t cheap. In Brazil, a pack of four pens can range from about R$ 1,400 to R$ 2,380, depending on the dose and discounts (PORTAL NORTE, 2025). Some say it could even hit R$ 3,700 per pack in different states due to taxes (UOL VivaBem, 2025). That’s stacks of money, especially if you need the drug for a while.

To see if it’s worth it, you’ve got to think about the cost, how well it works, and how it helps public health. Some studies say tirzepatide can be cost-effective in some situations. For instance, an analysis of the SURMOUNT-1 study showed the cost per pound lost could be competitive with other options, particularly at higher doses (PUBMED, 2025). Another study found it could add quality years to life for folks with diabetes and obesity, making it worth it based on US standards (PUBMED, 2025).

Still, studies point out that while tirzepatide works great, it might not be as cost-effective as other treatments, depending on how you slice it (PUBMED, 2024). Reviews of obesity meds show semaglutide (another hormone thingy) might be a better deal than tirzepatide, especially when you factor in long-term prices and results (PUBMED, 2024). So, it really boils down to making choices that fit each person, balancing how well it works with how much it costs.

Another thing to think about is the health system. In countries like Brazil, where the public health system is on a tight budget, adding pricey meds is a tough call. To include expensive treatments, committees have to carefully consider if the benefits are worth the cost and if everyone can get access to them. Deciding what to cover is part of figuring out if it’s worth it for the whole community.

Besides money and medicine, think about how it affects people’s lives. Losing weight can boost health stats, cut heart problems, make moving easier, and lower the chance of other issues linked to obesity. These perks are trickier to put a dollar amount on, but they definitely affect whether Mounjaro is worth it overall, because they can cut future costs from ongoing issues and hospital stays.

Bottom line: Whether Mounjaro is worth it depends on a bunch of things: how well it works, the price tag, how it improves lives, and the health system you’re in. The studies look encouraging for weight loss and dealing with related diseases, but the high cost and worry about cost-effectiveness compared to other choices mean you should be careful and consider each person individually (PUBMED, 2024; PORTAL NORTE, 2025). So, saying Mounjaro is definitely worth it means weighing the costs, medical benefits, public health goals, and the financial situation of both patients and healthcare systems.
