According to Dr. Moira Dolan, executive director of the Medical Accountability Network, "homicidal ideation" was added to the warning label of the antidepressant drug Effexor as a rare adverse event, in 2005. Yates, she said, had been taking 450 mg, twice the recommended maximum dose, for a month before killing her children. Dolan reviewed her medical record at the request of Rusty. "Yates had been prescribed Effexor in varying doses since shortly after her first suicide attempt in 1999, said Dolan, who reviewed her medical records after her first trial at the request of Rusty. A month before the murders, her daily dose had increased to 450 milligrams, twice the recommended maximum dose, Dolan said."
