I am on 10 mg Lexapro and 150 mg Wellbutrin. I have been on the Wellbutrin for some years, and was on 300 mg. I just started the Lexapro several weeks ago (5 mg for 4 days, then up to 10 mg). The 300 mg of Wellbutrin worked well for me, but I recently started another med for ADD which can be a problem with Wellbutrin at higher dosages so I have cut back on the Wellbutrin. It has been about 2 weeks that I have been on the 10mg Lex-150mg Well combination, and so far I feel pretty good. My doc wanted to raise my dosage of Lexapro to 20mg when I was there about 10 days ago, but I asked if we could wait another 30 days to decide. Having only been on Lexapro for 4 weeks at the time, and a week of that at the 5 mg level, I just thought it was too soon, and why take more if less will work? I am having some very minor side effects from the Lexapro, but they are certainly tolerable, given the benefit to my mood.
Good luck to you - I hope it works as well as it is for me.
