Understanding Bupropion Adverse Effects: What You Need to Know About This Medication's Side Effects

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

The most frequently reported side effects of bupropion tend to be mild and transient, often diminishing over time as the body adjusts to the medication. These common adverse effects include:

  • Dry mouth (xerostomia)
  • Insomnia
  • Headache
  • Nausea
  • Anorexia (loss of appetite)
  • 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.

Less Common but Notable Adverse Effects

While less common, some side effects of bupropion may be concerning for certain individuals. These include:

  • Tremors
  • Anxiety or agitation
  • Confusion
  • Hostility or aggression
  • Seizures (rare, but a significant concern)

Seizures are a particularly noteworthy side effect due to their potential severity. The risk of seizures is dose-related and more commonly associated with the high-dose formulations of bupropion.
