Is Wellbutrin Prescribed for Anxiety?
No, Wellbutrin (bupropion) is not FDA-approved for anxiety disorders. It's primarily approved for major depressive disorder and seasonal affective disorder, and as a smoking cessation aid under the brand Zyban.[1] Doctors sometimes prescribe it off-label for conditions like ADHD or sexual dysfunction from other antidepressants, but not routinely for anxiety.
Why Doesn't Wellbutrin Treat Anxiety Like SSRIs Do?
Wellbutrin works by boosting norepinephrine and dopamine levels in the brain, unlike SSRIs (e.g., Prozac, Zoloft) or SNRIs that mainly target serotonin, which calms anxiety more directly.[2] This mechanism can sometimes worsen anxiety symptoms, leading to agitation or restlessness in the first few weeks.
Can Wellbutrin Cause or Worsen Anxiety?
Yes, anxiety is a common side effect, affecting up to 5-10% of users in clinical trials. It's listed in the prescribing information as a potential adverse reaction, especially during initial dosing or dose increases.[3] Patients with pre-existing anxiety often avoid it for this reason.
When Might a Doctor Prescribe Wellbutrin with Anxiety?
In cases of depression with low energy or poor concentration—where SSRIs might cause weight gain or sexual side effects—doctors may try Wellbutrin cautiously. It's occasionally combined with anti-anxiety meds like benzodiazepines short-term, but evidence for standalone anxiety use is weak and mixed.[4] Always consult a doctor; self-adjusting risks serotonin syndrome or seizures.
How Does Wellbutrin Compare to Anxiety Meds?
| Medication | Primary Use | Anxiety Effect | Common Side Effects |
|------------|-------------|---------------|---------------------|
| Wellbutrin (bupropion) | Depression, smoking cessation | May increase anxiety | Insomnia, dry mouth, seizure risk (rare) |
| Lexapro (escitalopram) | Anxiety, depression | Reduces anxiety | Fatigue, sexual dysfunction |
| Buspar (buspirone) | Generalized anxiety | Specifically reduces anxiety | Dizziness, headache |
| Xanax (alprazolam) | Panic disorder | Fast relief | Addiction risk, sedation |
Wellbutrin stands out for fewer sexual side effects and no sedation, but it's not a first-line anxiety option.[5]
What Do Patients Report About Wellbutrin and Anxiety?
User reviews on sites like Drugs.com show split experiences: some with comorbid depression/anxiety report mood lifts without worsening nerves (average rating 6.9/10), while others quit due to heightened worry or panic.[6] Long-term data is limited for anxiety specifically.
