What is Zyban?
Zyban (bupropion) is a prescription treatment that helps people stop smoking. It contains bupropion, which works in the brain to reduce the craving for nicotine. Nicotine is the part of tobacco that causes addiction and makes quitting difficult.
Zyban works best when used with a stop-smoking program. These programs might include support groups, counseling, or advice to help you stay on track. Combining Zyban with support increases your chances of quitting for good.
Some people should not take Zyban. This includes anyone who has had seizures or eating disorders such as anorexia or bulimia. It is also unsafe for individuals who are already taking another product containing bupropion. Zyban is also not safe for people who suddenly stop drinking alcohol or using certain calming drugs.
Before using Zyban, talk to your doctor or pharmacist. They can help you decide if Zyban is safe for you and give you tips to support your quit-smoking journey.
Quitting smoking is one of the best steps you can take for your health. It lowers your risk of lung problems, heart disease, and some types of cancer.
How Does Zyban Work?
Zyban helps people quit smoking by changing how certain chemicals work in the brain. It affects two primary brain chemicals, dopamine and norepinephrine.
These chemicals play a role in mood, energy, and cravings. By balancing these chemicals, Zyban helps reduce the urge to smoke and makes withdrawal symptoms feel less intense.
Zyban does not affect serotonin, a brain chemical involved in mood regulation. It also does not block an enzyme called monoamine oxidase, which is linked to how some other drugs work.
Zyban Dose and Usage
Take Zyban in 150 mg sustained-release tablets by swallowing them whole. Start taking Zyban before your planned “quit date”, usually about one week before you stop smoking.
Begin the Zyban dose at a low level and increase it gradually to reduce the risk of side effects. Take Zyban with or without food, but never crush, split, or chew the tablets.
Dosage Form and Strengths of Zyban
Zyban is available as a 150 mg sustained-release tablet. Each tablet is purple, round, and film-coated, and it is designed to release the medication slowly in your body.
This helps maintain a steady level of the drug throughout the day. The Zyban dose is carefully adjusted to reduce the chance of side effects such as seizures.
How to Take Zyban?
- Start taking Zyban about one week before your planned quit date.
- For the first three days, take one 150 mg tablet once each day.
- After the first three days, take 150 mg twice a day, with at least eight hours between each dose.
- Do not take more than 300 mg of Zyban in a single day.
- You can take Zyban with or without food.
- Swallow each tablet whole. Do not crush, cut, or chew the tablets.
- Try to avoid taking Zyban close to bedtime to help prevent trouble sleeping.
- If you miss a dose, skip it and take the next tablet at the regular time. Do not take two doses at the same time.
- Continue taking Zyban for 7 to 12 weeks, or as advised by your doctor.
- Speak with your doctor if you think you need to take Zyban for more than twelve weeks.
- Your doctor may recommend using Zyban together with a nicotine patch for better results.
- If you have liver or kidney problems, your Zyban dose may need to be adjusted.
- Do not take Zyban with certain medications, such as monoamine oxidase (MAO) inhibitors like linezolid or methylene blue.
- Be sure to inform your doctor about all your health conditions before starting Zyban.
- Always follow the instructions on your prescription label and take the medication exactly as advised by your doctor.

Warnings and Precautions for Zyban
Zyban helps people stop smoking, but it has some important warnings and precautions. Zyban contains the same ingredient as some antidepressants, which means it can affect the brain and mood.
Even though it is not used to treat depression, it may still cause serious mental health side effects, especially in younger people.
Some of these side effects include suicidal thoughts, changes in behavior, or even seizures. Patients, families, and caregivers should closely monitor for any unusual changes, especially when starting or adjusting the dose.
- Zyban contains the same ingredient as some depression medications. It may increase the risk of suicidal thoughts or actions in children, teenagers, and young adults.
- People taking Zyban should be watched closely for signs of worsening mood, unusual behavior, or thoughts of hurting themselves.
- Families and caregivers should monitor the person taking Zyban daily and notify a doctor immediately if they notice any changes in mood, increased anger, or unusual behavior.
- Zyban may cause serious mood or mental health problems during smoking cessation, including depression, paranoia, hallucinations, panic, or suicidal thoughts.
- These mental health symptoms can happen in people with or without a history of mental illness, so all patients need careful monitoring.
- If the person taking Zyban becomes agitated, sad, or behaves in a way that is not normal for them, they should stop the medication and contact a doctor right away.
- In some people, mental health symptoms went away after stopping Zyban, but in others, they continued, so ongoing support is important.
- Zyban can cause seizures, especially if taken in high doses or by people who have risk factors for seizures.
- Do not take more than 300 mg of Zyban a day, and stop taking it if you have a seizure.
- Do not use Zyban if you have a seizure disorder, have or had an eating disorder like anorexia or bulimia, or if you suddenly stop drinking alcohol or taking certain medications like sleeping pills or anti-seizure drugs.
