Bupropion side effects overview: Bupropion, commonly known as Wellbutrin or Zyban, is an antidepressant and smoking cessation aid with a range of potential side effects, from mild to severe. Always consult a healthcare professional for personalized advice, as individual responses vary.

Common Side Effects

These occur frequently but often improve over time as your body adjusts. They include:

  • Dry mouth, constipation, nausea, and vomiting
  • Headache, dizziness, and sweating
  • Trouble sleeping (insomnia), agitation, and shakiness (tremor)
  • Fast heartbeat, blurred vision, and rash

Real-world note: Many users on health forums report dry mouth as the most persistent issue, often managed with sugar-free gum or hydration.

Less Common Side Effects

These may affect fewer people but warrant monitoring:

  • Weight changes, sore throat, or abnormal dreams (especially for smoking cessation)
  • Increased anger, confusion, ringing in ears (tinnitus), or changes in taste
  • Muscle pain, anxiety, or hot flashes

Patients sometimes describe feeling "jittery" initially, like a strong coffee buzz that fades after a week or two.

Serious Side Effects

Seek immediate medical help if you experience these, as they can be life- threatening:

  • Seizures (risk higher at doses over 450mg/day or with predisposing factors like alcohol withdrawal)
  • Suicidal thoughts or behavior, especially in young adults under 24
  • Allergic reactions: rash, hives, swelling, or difficulty breathing
  • Mania/hypomania in those with bipolar disorder, psychosis, or high blood pressure spikes
  • Angle-closure glaucoma or severe skin reactions

Case example: A 2024 report detailed a child accidentally ingesting bupropion, leading to seizures and hospitalization, highlighting overdose dangers even in small amounts.

Risk Factors & Management

  • Seizure threshold lowered by rapid dose increases, bulimia, or combining with alcohol/opioids
  • Monitor closely in first weeks; black box warning for suicidality
  • Tips: Take morning doses to minimize insomnia; stay hydrated for dry mouth

Recent Context (as of 2026)

TL;DR Bottom: Bupropion's side effects range from dry mouth/headaches (common, often mild) to rare but serious seizures/suicidality—discuss with your doctor. Information gathered from public forums or data available on the internet and portrayed here.
