Hi, I just started 150mg of Wellbutrin Extended Release. Today is day 2. I was just wondering how long does it take for a person to start feeling side effects? Would I be feeling them now or will they come in 2-4 weeks when the medicine is more in my system? How early into your medicine did your side effects start?

Hello texasgirl28. It truly varies from individual to individual. Wellbutrin (Bupropion) is as a whole, generally a fairly kind drug in regards to side effects. Some common ones are weight loss,(most people shed pounds instead of gaining) insomnia, anxiety. Side effects are generally felt from the onset of taking the drug. Therapeutically, it will take more often than not, four weeks time for the drug to work at its intended potential. regards, pledge
