welbutrin is used for many things - depression, as well as contorlling otherwise uncontrolable urges in sexual disorders and over eatingdisorders and also as a supressor to help people quit smoking.

it is a suppressor drug. It supresses sexual urges which is why at times on people like rapists are being prescribed it, and it also suppresses eating urges also which is why when prescribed as an anitdepressant it is not recommended for people with eating disorders and when people with eating disorders are prescribed this for their depression they need to be closely monitored.

When I looked in my prescription drug book it does say impotence is a sideeffect.
