I took Wellbutrin 150 for about a year and did not gain weight. I went up to 300 in May and still have not gained all the weight back from my last anxiety attack. So in my case, no it does not make me gain weight.
Wellbutrin was given to me as because I was depressed and had an eating disorder. It was supposed to be for depression but ended up helping with weight loss and quitting smoking
different people respond differrently to medications i gained weight on abilify and respiridone i am 200 lbs now and only you can take the risk good luck :)
I have never lost weight and I am on the XL if anything i have gained and stayed the same for some time.
If anything you will lose a little weight.
