Brazil's National Health Surveillance Agency (Anvisa) has issued a warning regarding the potential dangers associated with the use of weight loss pens, particularly in individuals with obesity or diabetes. This comes in light of an investigation into cases of pancreatitis among users of these medications, with six suspected deaths and over 200 reports of pancreatic issues being recorded. Although these reports are still considered suspicious and a direct cause-and-effect relationship has not yet been established, the rising number of notifications has prompted the agency to take action.

The profile of users under investigation generally includes individuals who suffer from obesity, diabetes, or both—conditions that inherently increase the risk of developing health problems, including pancreatitis. Medications like Ozempic, Saxenda, and Mounjaro, which fall under the category of weight-loss pens, have already included warnings about potential risks like gallbladder stone formation in their packaging. These risks could potentially escalate into pancreatitis, leading to serious health consequences for users.

As the investigation continues, healthcare professionals are urged to monitor patients closely when prescribing these medications. The findings raise critical concerns about the usage of such weight-loss drugs without proper medical supervision, especially given their side effects and the populations that are most at risk. This situation highlights the necessity for informed consent and comprehensive health evaluations before starting treatments that could have significant implications on patient health.
