But, until it does so, the idea of commercial pilots, or ATCO's, on anti-depressants and / or tranquillizers is an absolute and total NON-STARTER ! !
Australia is very enlightened in this regard. Taking anti-depressants in itself is not a disqualifier to any licence holder, including ATPL. Whether the Department gives an applicant the thumbs up though would depend on the clinical assessment I guess, but they certainly do all they can to keep you in the front seat.
