Murder defendant Kevin Ray Underwood has been on drugs prescribed for depression, anxiety, panic disorder, post-traumatic stress syndrome, social phobia and an excessive-compulsive disorder.
Underwood, accused of killing a Purcell girl, wrote in an Internet blog he used the drug known by the brand name Zoloft then changed to one with the brand name Lexapro. Investigators reported finding an empty pack for Lexapro in his Purcell apartment.
But no scientific evidence exists that the prescription medications would have contributed to any violent behavior, said Dr. Arthur Rousseau, a psychiatrist with a private practice in northwest Oklahoma City.
The two drugs, Rousseau said, are considered "good medicines" that are "next to impossible to overdose on."
In fact, the drugs are used to heighten serotonin levels in the body and "sharpen an individual's sense of well-being," said Phil Woodward, executive director of the Oklahoma Pharmacists Association.
Other drugs -- such as Prozac, Celexa and Paxil -- "pretty much perform the same function," Woodward said.
Low serotonin levels in the body "may precipitate feelings of depression," Woodward said.
