was about all the info i could find, nothing in the TGA's list or search.
As a 'tricyclic anti-depressant', i'd assume it IS available for prescription off label use, a psychiatrist of mine was trying to get my to try these sorta of drugs to deal with my depression. But as stated, i was afraid of the risk MAO Inhibitors may have on my drug use.
Although, what wiki said its not specifically a tricyclic, just similar... SSRE sounds interesting enough.
scratch that, just re-read the wiki, and: "Legal status: Prescription Only (S4)(AU)"
We aren't allowed to source these things for you as, our kind mod above has stated, so ii'll say only this. Go have a discussion with your GP about depression, what your coping with (if that is the case and you dont want this drug for abusive purposes). Talk about different types of anti-depressant drugs and make an informed statement in regards to this particular drug. He'll most likely prescribe it for you - if only to trial for your symptoms.
It does however, sound promising.
