Zyban SR tablets contain the active ingredient Bupropion Hydrochloride, which is a medicine used to help people who are addicted to nicotine to give up smoking.

Bupropion belongs to a group of medicines called antidepressants and was first developed to treat depression.

Bupropion acts in the brain but is not the same as nicotine replacement therapy. It works by blocking the re-uptake of a certain chemical substance in the brain called neurotransmitters (noradrenaline and dopamin).

Zyban SR relieves the withdrawal symptoms that you experience when you stop smoking (such as craving, anxiety, restlessness, headaches, irritability, hunger, difficulty with concentration, or just feeling awful).

Zyban SR is also popular as an add-on medication in cases of incomplete response to first-line SSRI antidepressants.


Zyban SR is available in:

  • 150mg Min Dosage

Take Zyban SR by mouth with a full glass of water with or without food. If stomach upset occurs, take with food to reduce stomach irritation.

Swallow Zyban SR whole. Do not break, crush, or chew before swallowing.

Usual dosage of Zyban SR is 1 tablet once a day for the first 6 days, increasing on day seven to 1 tablet twice a day.

Elderly people, those with any kidney or liver problems and people with a higher risk of fits should continue taking Zyban SR once a day and not increase to twice a day.

Take Zyban SR at the same times each day at least 8 hours apart. This may help to decrease the risk of seizures with this medicine.

Start taking Zyban SR 1 to 2 weeks before you quit smoking. Take Zyban SR for 7 to 12 weeks after you stop using tobacco. You can take it for as long as 6 months to a year.

If you want to achieve most effective results do not stop taking Zyban SR suddenly.

Missing a dose

Do not take double dose. If you miss a dose you should take it as soon as you remember about your missing. If it is the time for the next dose you should continue your regular dosing schedule.


If an overdose occurs and you are not feeling well, you should seek emergency medical attention or contact your healthcare provider immediately.


Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F) and away from excess moisture and heat. Throw away any unused medicine after the expiration date. Keep out of the reach of children.

What are people saying about the Canadian Pharmacy?

With so much fraud on the internet, I wasn’t sure you were not one of them. I decided to take a risk and ordered Cialis Soft. CP did an amazing job helping me on each stage until my order arrives, including phone consulting and helping to choose the most appropriate delivery and payment methods. I Wholeheartedly recommend you as «the full package deal» - a team of professionals! – Wilson Leroy

I have tried both Viagra and Cialis. Both have their pros and cons. I get a better and more consistent erection with Viagra. It started working after about 30 mins and it really carries on for a good 24 hrs. I get occasional headaches from Viagra, but the result is definitely well worth it! – Martin Moore

I'm 65 and I suffered ED after a heart attack. I decided to try Viagra. I started from min dosage 25mg. All I can say is that it works extremely well for me. Mild flushing in my face but certainly not bothersome. Very pleased! – Jonathan Harris

I was very skeptical, but did ended up getting Viagra Super Active. I can't recommend these pills enough. I feel like a man all over again. Thank you! – Henry Petersen

I’m grateful for sending me your catalogue. I want to compliment you on the excellent ED meds you provide. It was certainly worth the money and enabled me to satisfy my lover. As a result, I have regular sex life and happier marriage. – Kevin Durand

Thank you so much on the excellent job!! I made an order on February 4th. I also paid for the fast ship 3 to 5 days delivery. I haven't got any problems with that. All meds were delivered in time, with no damages. Definitely will buy more meds from you!!! – Phil Doherty

Canadian Pharmacy is quite simply the best drug store I've been offered in a very long time. I initially went to the doctor for ED and found out I had diabetes. I have ordered Cialis on and off for the past year and it works great within 30-60 min. More than appropriate price for the enjoyment! Great deal! – Paul Robinson
