A few years ago I was hired by the FAA to defend the agency against a suit brought by a pilot who wanted to fly while taking a prescription antidepressant. I helped the FAA formulate its defense of the agency’s ban on pilots using antidepressants and, as a result, the ban remained in effect. Pilots remained unable to fly while taking antidepressants, including the newer ones such as Prozac, Paxil, Zoloft, Celexa, Lexapro and Effexor. How times have changed.
