Does Wellbutrin Aid Smoking Cessation?
Yes, Wellbutrin (bupropion) helps with smoking cessation. The FDA approved it as Zyban in 1997 specifically for this purpose, based on clinical trials showing it doubles quit rates compared to placebo. In one study of over 600 smokers, 30% on bupropion quit for 7 weeks versus 14% on placebo.[1] It reduces nicotine cravings and withdrawal symptoms like irritability by blocking dopamine and norepinephrine reuptake.
How Does Bupropion Work for Quitting Smoking?
Bupropion mimics nicotine's effects on brain reward pathways without the high. Users start 1-2 weeks before quit date, typically at 150 mg daily, increasing to 300 mg. It curbs urges more effectively in moderate-to-heavy smokers (10+ cigarettes/day).[2] Success peaks around weeks 7-12, with 20-30% abstinence rates at 6 months in trials.
Zyban vs. Wellbutrin: What's the Difference?
Zyban is the same drug as Wellbutrin but branded for smoking cessation. Wellbutrin treats depression, but doctors prescribe it off-label for quitting. No chemical difference—both are bupropion hydrochloride. Generic versions work identically and cost less.[3]
How Effective Is It Compared to Other Quit Aids?
Bupropion matches Chantix (varenicline) in efficacy, with 25-30% success at 6 months versus 10-15% for nicotine patches alone. Combining with patches boosts rates to 35%. It's less effective for light smokers or those with depression history.[4]
| Aid | 6-Month Quit Rate | Common Use |
|-----|------------------|------------|
| Bupropion | 23-30% | Cravings/withdrawal |
| Varenicline | 25-33% | Receptor blocker |
| Nicotine replacement | 15-20% | Replacement therapy |
| Placebo | 10-15% | None |
What Are Common Side Effects and Risks?
Dry mouth (40%), insomnia (30%), and nausea (20%) are frequent but mild. Rare risks include seizures (0.1% at 300 mg dose, higher in bulimia or alcohol withdrawal). Avoid with MAOIs or abrupt alcohol cessation. Not for those with seizure disorders.[5] Monitor mood—some report anxiety spikes.
Who Should Avoid It and What If It Doesn't Work?
Skip if pregnant, breastfeeding, or under 18. For non-responders, switch to varenicline or counseling. Behavioral therapy doubles success with any med. Long-term use beyond 12 weeks lacks strong data.[6]
Cost, Availability, and Patent Status
Generics cost $20-50/month without insurance. Zyban patent expired in 2006; no barriers to generics.[7] Available by prescription only—check DrugPatentWatch.com for formulation patents.
