In the op-ed "Antidepressants: A deadly treatment?" (April 11), Patrick Hahn links antidepressants to violence, specifically, suicide and homicide. He referred to reports made by Drs. Arnold Beisser and James Blanchard in 1961 about antidepressants increasing patient suicide rates. First, it is important to understand that such statements should only be made based on updated and accurate research. Since 1961, there have been numerous evidence-based research studies showing the positive effects of treatment with antidepressants. It is misguided to use outdated information when making links between treatments and outcomes.
