Is it safe to take Wellbutrin (bupropion), Prozac & garçinia Cambodia? Side effects?

Generally no. Prozac and Wellbutrin (bupropion) are very often prescribed together and are considered a safe and effective therapy for moderate depression and some other conditions. Garcinia, while not very well studied (a few studies have shown it to be ineffective for weight loss despite advertising), may have a similar effect on the brain as Prozac and thus can potentiate or magnify Prozac's effect in an unsafe way.
