how long does it take for bupropion to work

Bupropion (Wellbutrin) generally takes about 1 to 2 weeks to start working, with noticeable improvements in sleep, energy, or appetite during this time. However, full therapeutic effects, especially for improving mood and motivation related to depression, often take around 6 to 8 weeks or sometimes longer to develop. Some people may see small benefits earlier, but maximum improvement usually requires consistent use over several weeks. Regular follow-up with a healthcare provider is important during this period to monitor progress and adjust dosage if necessary.
