Drug Information
5 reviews for Bupropion (Zyban)
Zyban contains bupropion, a medicine that helps people stop smoking. It is also used as an antidepressant under other brand names.
It works best when combined with support, such as advice from a stop-smoking service.
What is it used for?
- Helping adults stop smoking
How does it work?
Bupropion increases two brain chemicals, dopamine and noradrenaline, which help with mood, motivation and energy. It also reduces nicotine cravings and withdrawal symptoms.
This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.
- Antidepressants can, rarely, cause thoughts of self-harm or suicide, especially in people under 25 and in the first few weeks. Tell someone close to you that you are taking it and ask them to tell you if they notice changes in your mood or behaviour.
- Do not take it with, or within 2 weeks of, an MAOI antidepressant (such as phenelzine or selegiline), or with linezolid or methylene blue.
- Taking it with other medicines that raise serotonin (other antidepressants, tramadol, triptans for migraine, lithium, St John's wort) can cause serotonin syndrome.
- It can raise the risk of bleeding, especially with aspirin, ibuprofen, naproxen or blood thinners.
- Tell your doctor if you have epilepsy, bipolar disorder or mania, glaucoma, heart problems, liver or kidney problems, or diabetes.
- Do not stop taking it suddenly. This can cause withdrawal symptoms like dizziness, electric-shock feelings, bad dreams and irritability. Your doctor will lower the dose slowly.
- It may make you sleepy or dizzy. Do not drive until you know how it affects you, and avoid alcohol.
- Tell your doctor if you are pregnant, planning a pregnancy or breastfeeding.
- Do not take it if you have epilepsy or have ever had a seizure, an eating disorder (anorexia or bulimia), or if you are suddenly stopping alcohol or sedatives. These raise the risk of seizures.
- Do not take it with other products that contain bupropion.
- It can raise blood pressure.
- Tell your doctor or pharmacist about every other medicine, vitamin or herbal product you use.
- Keep this product out of the reach and sight of children.
Like all medicines, Zyban can cause side effects, but not everybody gets them.
Common side effects
- Trouble sleeping
- Dry mouth
- Headache
- Feeling sick
- Feeling anxious or shaky
These are usually mild and often get better as your body gets used to it. Tell your doctor if they bother you or do not go away.
Stop using it and get medical help straight away if you notice:
- Thoughts of harming yourself or ending your life
- Feeling very high, overexcited or reckless (mania)
- Fever, sweating, shaking, muscle twitching, fast heartbeat and confusion (possible serotonin syndrome)
- A fit (seizure)
- Unusual bleeding or bruising, or black stools
- Confusion, headache and weakness, especially in older people (low sodium)
This is not a complete list. If you notice anything unusual, ask your doctor or pharmacist.
- Set a quit date. Start taking it 1 to 2 weeks before that date while you are still smoking.
- Take 150 mg once a day for the first 3 days, then 150 mg twice a day, at least 8 hours apart.
- Swallow the tablet whole. Do not crush, chew or split it.
- Carry on for 7 to 12 weeks. If you have not stopped smoking after 7 weeks, talk to your doctor.
If you miss a dose: Take it as soon as you remember, unless it is nearly time for your next dose. Never take two doses at once.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
How to store it: Keep it in its original pack at room temperature (below 25°C / 77°F), away from heat, damp and direct sunlight. Do not use it after the expiry date.
- QWhy do I start Zyban before my quit date?
- A
It takes about a week to build up in your body and start reducing cravings.
- QCan I use nicotine patches with Zyban?
- A
Sometimes, but only if your doctor agrees, and your blood pressure should be checked.
- QWhat if I slip and smoke a cigarette?
- A
Keep going. A slip is common. Keep taking the tablets and try again.

I placed an order last week and it was handled well. Payment went through smoothly on the first try. Live chat was handy and the answers were useful. Also, everything was in order when I opened the box. All good on my side!
