When it comes to quitting smoking, Zyban is a brand name for bupropion, an atypical antidepressant that also helps reduce nicotine cravings. But it isn’t the only game‑changer on the market. In 2025 there are several prescription drugs, over‑the‑counter nicotine products, and even herbal extracts that claim to boost quit rates. This guide breaks down the key differences-efficacy, side‑effects, cost, and usage patterns-so you can decide which path fits your lifestyle and budget.
Quick Takeaways
- Zyban (bupropion) offers a solid 12‑week quit‑rate of ~25% and works well for people who dislike nicotine‑based products.
- Varenicline (Chantix) is the most effective single medication, with quit rates around 30‑35% but a higher risk of nausea and mood changes.
- Nicotine replacement therapy (patch, gum, inhaler) is safest for most users, though success hinges on strict adherence.
- Cytisine, a plant‑derived pill sold in some countries, shows comparable efficacy to varenicline at a fraction of the price.
- Combining medication with behavioral counseling boosts success by 10‑15% across all options.
How Zyban Works and Who It’s Best For
Bupropion blocks the re‑uptake of dopamine and norepinephrine, two brain chemicals that fuel nicotine cravings. By keeping these neurotransmitters elevated, Zyban reduces withdrawal symptoms without delivering any nicotine. The usual regimen starts one week before the quit date: 150mg once daily for three days, then 150mg twice daily for the remaining 11 weeks.
- Ideal candidates: Adults who have tried nicotine patches or gum without success, people with a history of depression (bupropion can improve mood), and smokers who prefer an oral tablet over a nicotine patch.
- Key drawbacks: Possible insomnia, dry mouth, and a rare risk of seizures-especially at doses >450mg/day or in people with eating disorders.
Prescription Alternatives: Varenicline and Cytisine
Varenicline is sold under the brand name Chantix and works by partially activating nicotine receptors while blocking nicotine itself. This dual action eases cravings and reduces the pleasure of smoking.
Typical dosing starts a week before quitting: 0.5mg once daily for three days, then 0.5mg twice daily for four days, and finally 1mg twice daily for the remaining 11 weeks.
- Success rate: 30‑35% abstinence at 12weeks in large RCTs (e.g., the 2022 Cochrane review).
- Side‑effects: Nausea (most common), vivid dreams, and, in rare cases, mood swings.
Another low‑cost option is Cytisine, a plant‑derived alkaloid used in Eastern Europe for decades. Its mechanism mirrors varenicline’s partial agonism, but the pill regimen is shorter-1mg three times daily for 12weeks.
- Success rate: Around 27% in a 2023 multicenter trial, close to varenicline.
- Cost: Approximately AU$30 for a full course, making it the most affordable prescription‑level aid.
Nicotine Replacement Therapy (NRT) Options
Traditional NRT delivers controlled nicotine to ease withdrawal while you wean off cigarettes. The main formats are:
- Nicotine Patch: A transdermal patch releasing 21mg (high‑dose) or 14mg (low‑dose) nicotine over 24hours. Use for 8‑12 weeks, stepping down the dose.
- Nicotine Gum: Chewed intermittently for cravings; 2mg or 4mg strengths. Recommended for 6‑12 weeks.
- Nicotine Inhaler: A handheld device that mimics the hand‑to‑mouth motion of smoking. Delivers 6mg nicotine per hour.
Because NRT provides nicotine, it avoids the seizure risk of bupropion and the nausea of varenicline. However, success hinges on proper dosing and consistent use-missed patches or chewing the gum too quickly can reduce effectiveness.
Other Off‑Label and Adjunct Options
Some clinicians prescribe Clonidine, an antihypertensive that can blunt withdrawal symptoms, especially in heavy smokers. Evidence shows modest quit rates (≈15%) but significant sedation, so it’s usually a backup when first‑line therapies fail.
Behavioural counseling-whether one‑on‑one, group, or digital-adds a psychological layer that improves outcomes across the board. A 2024 meta‑analysis found that adding counseling increases quit rates by roughly 12% regardless of the medication used.

Choosing the Right Path: Decision Checklist
- Do you want to avoid nicotine entirely? Zyban and Cytisine are nicotine‑free options.
- Is cost the primary driver? Cytisine and NRT (especially generic gum) are the cheapest.
- Do you have a history of mood disorders? Zyban may improve mood, but discuss seizure risk with your doctor.
- Can you tolerate nausea? If not, start with NRT or Zyban before trying varenicline.
- Will you use counseling? Pair any medication with a quit‑line or digital program for a 10‑15% boost.
Real‑World Scenarios
Case 1 - Heavy smoker, previous patch failure: John, a 42‑year‑old accountant, tried 21mg patches for six months without quitting. His doctor prescribed Zyban because he wanted a nicotine‑free approach. After a three‑week titration, John reported reduced cravings and successfully stopped smoking at week 8.
Case 2 - Young professional, price‑sensitive: Maya, 27, prefers an affordable solution. She opted for cytisine after reading about its $30 price tag and comparable success rate. She completed the 12‑week course with minimal side‑effects and remains smoke‑free after six months.
Case 3 - Pregnant smoker, cautious about meds: Laura, 31, is pregnant and cannot use prescription drugs. She used nicotine gum combined with a government‑funded quit‑line, which helped manage cravings without exposing the fetus to bupropion or varenicline.
Tips to Maximize Your Quit Success
- Set a quit date and start medication a week ahead (except NRT, which can begin immediately).
- Track cravings in a journal; notice patterns and plan distractions.
- Stay hydrated-dry mouth from Zyban or nicotine gum is easier to manage with water.
- Lean on support-family, friends, or online communities improve adherence.
- Watch for interactions-avoid MAO‑inhibitors with bupropion and limit alcohol if using varenicline.
Frequently Asked Questions
Can I use Zyban and nicotine gum together?
Yes, many clinicians combine bupropion with NRT to cover both the chemical and behavioural aspects of addiction. Studies show the combo can raise quit rates by up to 8% compared to either product alone.
Is cytisine available in Australia?
As of 2025, cytisine is not yet listed on the Australian Therapeutic Goods Administration (TGA) schedule, but it can be imported with a doctor's prescription under special access schemes.
What should I do if I experience seizures on Zyban?
Stop the medication immediately and seek emergency care. Discuss alternative therapies (e.g., varenicline or NRT) with your doctor once you’re stable.
How long should I stay on varenicline?
Standard treatment lasts 12 weeks, followed by an optional 12‑week taper to reduce relapse risk. Some clinicians extend therapy up to six months for high‑risk smokers.
Are there any dietary restrictions with bupropion?
Avoid high‑dose vitamin B6 supplements, as they can increase seizure risk when combined with bupropion. Otherwise, there are no major food interactions.
Bottom Line
There’s no one‑size‑fits‑all answer. Zyban shines for people who want a nicotine‑free pill and have a mild‑to‑moderate withdrawal profile, while varenicline delivers the highest quit rates at the cost of more gastrointestinal side‑effects. Nicotine replacement products remain the safest, especially when paired with free counseling services. Cytisine is emerging as a budget‑friendly contender, but accessibility can be a hurdle in Australia.
Start by evaluating your health history, budget, and willingness to tolerate side‑effects. Then match that against the decision checklist above, talk to a healthcare professional, and lock in a quit date. With the right combination, you’ll be on a solid path to a smoke‑free life.
