Hi, I have been on Effexor XR for 3 years and
I have gained about 40-50pounds, most when
my dose was increased to 225, now I am on 75mg b/c I'm getting ready to wean off the medicine in a couple of weeks,and I haven't lost anything yet. My eating habits have not changed and I exercise. I have always been underweight and I could eat whatever I wanted...I'm only
26 years old...I know my metabolism has changed some, but not enough to pack on 40 pounds.
