Bupropion, commonly known by the brand name Wellbutrin, is a medication primarily prescribed for the treatment of major depressive disorder (MDD) and seasonal affective disorder (SAD). Additionally, it is often used off-label for smoking cessation under the brand name Zyban. As with any medication, understanding the potential adverse effects of bupropion is crucial for patients and healthcare providers to ensure safe and effective treatment. This article aims to provide a comprehensive overview of the side effects associated with bupropion, including common, less common, and rare but serious adverse effects.
Common Adverse Effects of Bupropion

- Dry mouth (xerostomia)
- Insomnia
- Headache
- Nausea

- Weight loss
These side effects are usually manageable and may not require discontinuation of the medication. However, it is essential for patients to discuss any bothersome or persistent side effects with their healthcare provider.
