Wellbutrin is an antidepressant medication; more specifically, it’s a norepinephrine and dopamine reuptake inhibitor (NDRI) used mainly to treat major depressive disorder and prevent seasonal affective disorder.

What type of drug is Wellbutrin?

  • The active ingredient in Wellbutrin is bupropion, which belongs to the aminoketone class of antidepressants.
  • Pharmacologically, it is classified as a norepinephrine and dopamine reuptake inhibitor (NDRI), meaning it increases the levels of these two brain chemicals, which can help improve mood and energy.
  • It is not an SSRI (selective serotonin reuptake inhibitor) and works differently from common antidepressants like sertraline or escitalopram.

How Wellbutrin is used

  • Wellbutrin SR and Wellbutrin XL are approved to treat major depressive disorder in adults, and the XL form is also approved to help prevent seasonal affective disorder.
  • Bupropion is sometimes prescribed off-label for conditions like bipolar depression or as part of smoking cessation treatment (in other brand forms), but those uses depend on a clinician’s judgment.
