Bupropion (Wellbutrin) is an atypical antidepressant affecting dopamine and norepinephrine rather than serotonin. Withdrawal is generally milder than SSRI/SNRI discontinuation. How to taper off bupropion typically takes weeks rather than months. Always work with your prescriber.
Why bupropion is easier
Bupropion’s mechanism (dopamine/norepinephrine reuptake inhibition) doesn’t produce the serotonin-related withdrawal characteristic of SSRIs. Brain zaps, severe dizziness, and the classic SSRI discontinuation syndrome are uncommon.
Typical tapering approach
- From 450 mg: reduce to 300 mg for 2 weeks
- 300 mg to 150 mg for 2 weeks
- 150 mg to 100 mg or lower for 2 weeks
- Discontinuation
Total duration: 2-6 weeks for most patients.
Available formulations
- Bupropion IR: 75 mg, 100 mg
- Bupropion SR: 100 mg, 150 mg, 200 mg
- Bupropion XL: 150 mg, 300 mg
Common withdrawal symptoms
Generally milder:
- Mood changes
- Fatigue
- Possible return of original symptoms (depression, ADHD, etc.)
- Mild flu-like symptoms occasionally
Considerations
Bupropion is also used for smoking cessation (Zyban) and seasonal depression. Discontinuation context matters — stopping after smoking cessation differs from stopping after major depression treatment.

The bottom line on tapering off bupropion
Bupropion taper is generally simpler than SSRI tapers. Weeks rather than months for most patients. Discuss with prescriber.
