Weight loss appears to be comparable between the Wegovy injection and the pill
Like other weight loss injections such as Mounjaro and Nevolat, Wegovy works in stages, starting off at a low potency and gradually increasing to a suitable maintenance level
Wegovy works best when combined with healthy lifestyle changes, explains Andrew Shapiro, MD, surgeon at Advanced Surgical Physicians and the medical director of the Comprehensive Breast Center at Wellington Regional Medical Center
Anaphylactic reactions are extremely rare but have been reported with GLP-1 receptor agonists
