I was taking lofepramine ( a tricyclic ) for around a year. It disrupted my periods somewhat, but then they abruptly stopped. I didn't have a period for four months. I then changed to a different type of a/d ; trazodone. Lo and behold my periods came back as normal ! Has anyone else had similar problems, experiences ? I did bring it up with my doctor who was no help whatsoever. Now that my cycle seems to have gone back to 'normal' I'd like to discuss with my doctor how this happened.
