Several Botox users and their relatives filed a lawsuit Wednesday in Orange County, Calif, contending that the drug injured them or killed their relatives. They blamed maker Allergan Inc for failing to warn them of the dangers.

The suit links the drug to 4 deaths, including a 69-year-old nurse who received Botox injections for neck and shoulder pain, a 7-year-old girl with cerebral palsy who allegedly receivied injections to control limb spasticity, and a 71-year-old woman allegedly got Botox injections for wrinkles around her mouth at a mall clinic, and a New Jersey man who died, the suit contends, as a result of Botox injections.
