I took the lowest dose of Wellbutrin for a few months because according to Medlineplus it's the antidepressant that doesn't have a side effect of weight gain, and it can cause a little weight loss. My GP just went along with my suggestion on that. While I was taking it I was at the lower end of my normal weight range. My weight normally ranges only about 5-8 lbs., and the average is in the middle, so it was a very small decrease. However, I was diagnosed with some hearing loss right after I took it, which I found out is a side effect of Wellbutrin. I don't know if hearing loss is a side effect of other antidepressants. You could look for the word ototoxic in the paperwork about the medications, which I expect you can also find online. Ototoxic means hearing loss, and that is the word they used in the list of side effects. Although the Wellbutrin helped my mood, it was not worth it to me to have taken it. The hearing loss is very frustrating to deal with at work.
