Not all possible side effects are listed here, so please consult with your doctor or pharmacist if you need more information.

A special note about seizures:

Please note that while seizures are a rare side effect of Wellbutrin, the risk is still about four times greater than it is with other antidepressants. You should notify your doctor if you belong to any of the following groups, as these factors may increase your risk of a seizure even further:

  • You have a seizure disorder
  • You are taking any other medications that contain bupropion, including the smoking cessation drug Zyban
  • You have an eating disorder, such anorexia or bulimia

A special note about suicide:

Data analysis has shown that antidepressant drugs like Wellbutrin may increase the risk of suicidal thoughts and behavior in children, teens, and young adults (aged 18-24). This increased risk does not appear to be present in older individuals, however. Patients and their caregivers should be aware of any increasing depression, suicidality, or changes in behavior and seek prompt medical attention if these occur. The early stages of treatment and dosage changes are times of particular concern.
