Drug Class

Norepinephrine-Dopamine Reuptake Inhibitor (NDRI) / Atypical Antidepressant

Pregnancy

Category C — Some observational data suggest a small increased risk of congenital cardiac defects with first-trimester exposure, though findings are inconsistent. Use during pregnancy only if the potential benefit justifies the potential risk; bupropion may be considered when smoking cessation in pregnancy is clinically prioritized.

Available Forms

Oral immediate-release tablet (75 mg, 100 mg), Oral sustained-release tablet — SR (100 mg, 150 mg, 200 mg), Oral extended-release tablet — XL (150 mg, 300 mg, 450 mg), Oral extended-release tablet — Aplenzin hydrobromide salt (174 mg, 348 mg, 522 mg)

What It's Used For

is prescribed to treat:

• Depression, seasonal affective disorder, and smoking cessation • Various related conditions in the mental health category • Associated symptoms and complications

It is an important medication that helps manage these conditions effectively.

Dosage Quick Reference

These are general dosage guidelines. Your doctor will determine the appropriate dose for your specific situation.

Condition	Starting Dose	Maintenance Dose
Major depressive disorder (XL)	150 mg once daily in the morning	300 mg once daily after 4 days; max 450 mg/day
Major depressive disorder (SR)	150 mg once daily in the morning	150 mg twice daily (separated by ≥ 8 hours); max 400 mg/day
Seasonal affective disorder (XL)	150 mg once daily in autumn	300 mg once daily; continue through winter and taper in spring

Side Effects

Common side effects may include:

• Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Bupropion is a moderate CYP2D6 inhibitor and is itself metabolized to active metabolites, creating several clinically meaningful interactions.

MAO inhibitors (e.g., phenelzine, tranylcypromine, linezolid, IV methylene blue): Concurrent use is contraindicated due to risk of hypertensive crisis. Allow at least 14 days between discontinuing an MAOI and starting bupropion.
CYP2D6 substrates with narrow therapeutic indices (e.g., metoprolol, propafenone, flecainide, certain tricyclics, tamoxifen): Bupropion can substantially increase plasma levels of these drugs. Lower doses of the CYP2D6 substrate may be needed; tamoxifen co-administration may reduce its anticancer activation.
Drugs that lower the seizure threshold (e.g., antipsychotics, tramadol, theophylline, systemic corticosteroids, other antidepressants): Bupropion has dose-related seizure risk (roughly 0.1% at doses ≤ 450 mg/day, rising sharply above). Combine cautiously and avoid in patients with seizure disorders, eating disorders, or abrupt alcohol/benzodiazepine withdrawal.
CYP2B6 inducers (e.g., ritonavir, efavirenz, carbamazepine, phenytoin): Decrease bupropion exposure and may reduce efficacy. Consider higher bupropion doses with monitoring.
Nicotine replacement therapy: May be combined with bupropion for smoking cessation but can cause modest blood pressure elevation; monitor blood pressure.
Alcohol: Both increase seizure risk and can produce neuropsychiatric effects. Minimize alcohol use; avoid abrupt cessation in heavy drinkers while on bupropion.

Frequently Asked Questions

Bupropion works on norepinephrine and dopamine rather than serotonin, so it generally does not cause the sexual dysfunction, weight gain, or sedation common with SSRIs — and it is often modestly activating rather than sedating. It is also the only first-line antidepressant that doubles as an FDA-approved smoking cessation aid.

Some patients notice improved energy and concentration within 1 to 2 weeks, but the full antidepressant effect typically takes 4 to 6 weeks. Sleep and appetite often improve before mood does. Continue taking the medication as prescribed even if early benefits seem modest.

Yes. Marketed as Zyban for this indication, bupropion roughly doubles the odds of successful long-term smoking cessation versus placebo. Treatment usually starts 1 to 2 weeks before your quit date and continues for 7 to 12 weeks. It can be combined with nicotine replacement therapy for additive benefit.

Bupropion lowers the seizure threshold in a dose-dependent way. The risk is approximately 0.1 percent at doses up to 450 mg/day but rises substantially at higher doses or with rapid dose increases. Avoid bupropion if you have a seizure disorder, current or prior eating disorder, or are abruptly stopping alcohol or benzodiazepines.

Generally no. Bupropion is weight-neutral or modestly weight-reducing in most patients and has the lowest rate of sexual side effects among modern antidepressants. These properties make it a common choice for patients who experienced these problems with SSRIs or SNRIs.

Heavy or binge drinking should be avoided because it increases seizure risk and can intensify neuropsychiatric side effects. Modest, occasional alcohol use is usually acceptable, but discuss your specific drinking pattern with your prescriber. Never abruptly stop heavy alcohol use while on bupropion without medical supervision.

Questions to Ask Your Doctor

Consider discussing these topics at your next appointment:

✓Is bupropion a good fit for my specific symptoms — particularly low energy, focus, or motivation?
✓How will we monitor for blood pressure changes or other side effects during treatment?
✓Are any of my current medications likely to raise my seizure risk in combination with bupropion?
✓If bupropion does not work or causes side effects, what would be the next step?
