[Financial News] Asan Medical Center has urged caution over online advertisements promoting weight-loss products as having the effects of 'natural Mounjaro' while using the names of its medical staff without authorization, calling them false advertisements involving the unauthorized use of doctors' names.
Recently, a series of weight-loss-related posts featuring the name of a professor at Asan Medical Center appeared on social media. The posts included statements such as, "I followed what the professor at Asan Medical Center called natural Mounjaro, and after taking only this for a week, I had already lost 3 kg and felt better."
The posts displayed various foods, including noodles, vegetables, shrimp and egg salad, alongside photographs, promoting them as though they had weight-loss benefits.
Asan Medical Center responded by stating that the advertisements were false and had used the names of its medical staff without authorization. It also issued a separate warning.
Asan Medical Center posted a notice on its official social media account titled "Warning Against Illegal Use of Names and False Advertisements." The hospital stated, "Recently, advertisements have been spreading online that use the name of Asan Medical Center and its former medical staff without authorization to induce people to purchase specific products."
The hospital also corrected the record regarding the doctor featured in the advertisements. It explained, "The professor in question is not currently employed by Asan Medical Center."
The hospital made clear that it has no connection whatsoever with the products. It added, "Asan Medical Center has absolutely nothing to do with these products and does not guarantee their effectiveness. Unauthorized use of the hospital's name to obtain commercial benefits is unequivocally illegal, so please exercise caution to prevent any harm caused by the links."
The doctor whose name was used in the advertisements also personally urged people to exercise caution. An endocrinologist who previously served as a professor in the Department of General Internal Medicine at Asan Medical Center, he wrote on his social media account, "Recently, advertisements have been spreading that misuse my name without authorization to induce people to purchase specific products. Using another person's name without permission to obtain commercial benefits is illegal. Above all, please exercise particular caution so that no one is harmed by these advertisements."
