About Zyban

Zyban contains bupropion as its active ingredient. Originally it was used to treat depression, but has been found to help people stop smoking by reducing cravings and other nicotine withdrawal symptoms. Zyban tablets are use in combination with lifestyle advice and support. It is thought bupropion works by affecting parts of the brain involved with addictive behaviour.

NowPatient offers bupropion under the brand name Zyban as a treatment for smoking cessation, following an online consultation with a prescribing clinician.

  • It can be dangerous if you take Zyban with certain medications. If you’re not sure if it is safe, discuss this with the prescribing clinician

Who is Zyban not suitable for?

Zyban may not be suitable for some people. To make sure it’s safe for you, speak to the prescribing clinician about any other medical conditions you may have, or if you:

  • Have had an allergic reaction to bupropion hydrochloride in the past

How and where to get Zyban?

Zyban is available, only with a prescription. It is not available over the counter at a pharmacy.

NowPatient does not allow customers to buy Zyban directly. Our service is certified, safe and effective, and we only ever treat conditions. If you book a consultation with a prescribing clinician for smoking cessation, you can discuss if Zyban is a suitable treatment option for you.

At the end of the consultation, the clinician will decide if a treatment plan is suitable for you. If it is, the clinician will issue you with a prescription which can then be ordered, paid for and delivered directly to your chosen address by NowPatient.

Dosage and strength for Zyban for smoking cessation

Zyban is available as 150 mg sustained release tablets when used for smoking cessation.

Information about how to take Zyban for smoking cessation

The recommended dose of Zyban is 1 or 2 tablets daily. Start taking Zyban one or two weeks before you try to stop smoking. This will give you the best chance of quitting smoking, as Zyban can take around a week to start working. You will normally take Zyban for around 7 to 9 weeks.

The effectiveness of Zyban improves if taken with other over-the-counter nicotine replacement therapy (NRT) treatments, such as nicotine patches, gum, lozenges, or sprays. For further medical advice speak to a healthcare professional at NowPatient.
