Key Takeaways
- Stopping Wellbutrin suddenly can cause a range of side effects including irritability, anxiety, insomnia, flu-like symptoms, and return of depression.
- The most serious potential side effect of abrupt discontinuation is seizures, particularly at doses above 300 mg.
- Side effects typically begin within 1-3 days of stopping and peak during the first week.
- Studies indicate that 10-20% of patients experience clinically significant discontinuation symptoms.
- The FDA recommends gradual dose reduction when discontinuing bupropion.
- Rebound depression after stopping Wellbutrin can be more severe than the original depressive episode.
What Happens When You Stop Wellbutrin Suddenly?
Wellbutrin (bupropion) works by increasing dopamine and norepinephrine activity in the brain. When you stop taking it suddenly, your brain must readjust to functioning without this chemical support. This readjustment period produces a range of side effects that collectively constitute discontinuation syndrome.
Physical Side Effects
The physical side effects of stopping Wellbutrin include:
- Headaches: Often constant and dull, sometimes severe
- Dizziness and lightheadedness: Particularly when standing up quickly
- Fatigue and lethargy: Profound tiredness that makes daily activities difficult
- Flu-like symptoms: Body aches, sweating, chills, and general malaise
- Nausea and digestive upset: Stomach cramps, diarrhea, or loss of appetite
- Tremors: Mild shaking, particularly in the hands
- Sleep disturbances: Insomnia, vivid dreams, or excessive sleepiness
Psychological Side Effects
The psychological effects can be equally or more distressing:
- Rebound depression: Return of depressive symptoms, often worse than before treatment
- Anxiety and panic: Heightened anxiety, sometimes progressing to panic attacks
- Irritability and anger: Emotional volatility and short temper
- Crying spells: Sudden, uncontrollable crying episodes
- Difficulty concentrating: Brain fog and trouble focusing
- Mood swings: Rapid alternation between emotional states
- Suicidal thoughts: In rare cases, particularly in younger adults (seek immediate help)
Seizure Risk
The most dangerous potential side effect of stopping Wellbutrin suddenly is seizures. Bupropion is known to lower the seizure threshold, and abrupt discontinuation can further destabilize neural activity. This risk is highest in individuals who:
- Were taking doses above 300 mg daily
- Have a history of seizures or epilepsy
- Use alcohol heavily
- Have an eating disorder
- Have experienced head trauma

Timeline of Side Effects
- Days 1-2: Initial onset of irritability, headaches, and sleep changes
- Days 3-7: Peak intensity of symptoms; most physical and psychological effects are strongest
- Weeks 2-3: Gradual improvement for most people; some symptoms linger
- Week 4+: Most side effects have resolved, though mood-related symptoms may persist longer
How to Minimize Side Effects
- Taper gradually: Reduce your dose incrementally over 2-4 weeks under medical supervision
- Stay active: Exercise can naturally boost dopamine and norepinephrine
- Maintain sleep hygiene: Consistent sleep schedules, cool dark room, no screens before bed
- Consider therapy: Counseling during discontinuation provides emotional support
- Communicate: Tell your doctor about any side effects so the taper can be adjusted
