What is Zyban?
Zyban tablets contain the active ingredient bupropion hydrochloride, which is a medicine used to help people who are dependant on nicotine to give up smoking. It acts in the brain but is not the same as nicotine replacement therapy. It is not fully understood how this medicine works to help people give up smoking, but it is known that bupropion affects neurotransmitters in the brain.
How does Zyban work?
Zyban works by affecting chemicals and neurotransmitters in the parts of the brain that influence nicotine withdrawal. This leads to reduced cravings and fewer unpleasant side effects. Zyban is thought to work best when used in combination with other therapies, such as attending counselling or a support group. Zyban supports smokers to quit the habit but determination, motivation, and willpower are still needed.
How to take Zyban
After a consultation with your doctor, you should start the course of Zyban whilst still smoking, aiming to stop completely within two weeks of starting the treatment. Tell your doctor about any medications you currently take.
Zyban tablets are slow release tablets so should be swallowed whole with a glass of water. It does not matter whether they are taken with or without food.
Always follow the instruction on the package leaflet or as directed by your doctor. The usual dosage for Zyban is:
One tablet for six days then;
One tablet twice a day, ensuring there are at least eight hours between doses.
Treatment usually continues for approximately nine weeks after you have stopped smoking. After nine weeks, you should stop taking Zyban; it is not intended for long-term use.
