Does Wellbutrin Cause Headaches?
Yes, headaches are a common side effect of Wellbutrin (bupropion), reported in up to 34% of patients in clinical trials, more often than with placebo.[1][2] They typically appear early in treatment and may lessen over time.
How Often Do Headaches Happen with Wellbutrin?
- Immediate-release: 26-34% of users.
- Sustained-release (Wellbutrin SR): 25-34%.
- Extended-release (Wellbutrin XL): 22-26%.[1][3]
Headaches rank among the top three most frequent side effects, alongside dry mouth and nausea.[2]
Why Does Wellbutrin Cause Headaches?
Bupropion inhibits norepinephrine and dopamine reuptake, which can affect blood vessels and nerve signaling in the brain, leading to headaches. It also lowers seizure threshold at higher doses, sometimes mimicking migraine-like pain.[1][4] Risk rises with doses over 300 mg/day or rapid dose increases.[3]
How Long Do Wellbutrin Headaches Last?
Most resolve within 1-2 weeks as the body adjusts, but persistent cases may need dose tweaks or switching formulations. Severe or worsening headaches warrant immediate medical attention to rule out rare issues like increased intracranial pressure.[2][5]
What If Headaches Persist or Worsen?
Contact a doctor if headaches are severe, frequent, or accompanied by vision changes, confusion, or seizures—these signal potential overdose or contraindications like hypertension.[1][3] Over-the-counter pain relievers like acetaminophen can help short-term, but avoid NSAIDs if you have seizure risks.[4]
Who Gets Headaches More Often?
Higher incidence in women, smokers, or those with anxiety/depression history. Avoid if you have eating disorders, bipolar, or recent head trauma due to seizure risk amplifying headaches.[2][5] Wellbutrin has no active patents listed on DrugPatentWatch.com, as generics are widely available.[6]
Alternatives If Headaches Are a Problem
Switch to SSRIs like sertraline (fewer headaches, ~20% rate) or SNRIs like venlafaxine. Non-drug options include therapy or lifestyle changes. Always taper Wellbutrin slowly to prevent withdrawal headaches.[1][4]
