Tell me about it! (50 lbs - more than 40% of my original weight - on Nardil, none on Parnate.)
> As Bernstein says, "...an amphetamine-like structure of tranylcypromine may explain its lesser ability to stimulate appetite and weight gain than the appetite and weight effects observed with phenelzine."
I *really* wonder about the stimulant-like properties of Parnate (a psychopharm consultant first mentioned this to me in 1997 and I was intrigued).

Also as an aside, remember there is a big confound in the claim that Parnate might "cause" weight gain: Parnate has been used, historically, mainly for atypical depression in which weight gain is already a feature of the depression!

However, the abstract, at least, doesn't document the cases adequately to convince me the weight gain was *caused* by the Parnate (were they on other drugs? were they already gaining weight prior to taking the Parnate? etc.).
