It is impossible for your healthcare provider to know whether or not you will develop insomnia while taking Wellbutrin. Also, in some cases, if a person does develop insomnia, it is challenging to know whether it is because of the condition or Wellbutrin itself. This is because insomnia is a common condition with depression.
If you are taking Wellbutrin and insomnia becomes a problem, make sure to talk with your healthcare provider. There are treatments that he or she may be able to recommend, including adjusting the Wellbutrin dosage or trying another medicine.
