In recent months, 22 people across 11 U.S. states have developed symptoms like blurry vision and shortness of breath after getting "counterfeit or mishandled" Botox injections outside medical settings, such as in spas and people's homes.

In an advisory issued Tuesday (April 23), the Centers for Disease Control and Prevention (CDC) alerted doctors to an ongoing investigation it's conducting with the Food and Drug Administration (FDA) and state and local health officials. The agency reported that 11 of the affected people were hospitalized and no one has died; the cases happened between November 2023 and late March 2024.
