How is Zyban taken?
If you do decide to take Zyban, you need to start taking it one week before your set date for stopping smoking. During the first week of taking Zyban, you need to take one tablet containing a dose of 150mg bupropion. Stop smoking on your 7th day of treatment and increase your dosage to two 150mg tablets per day, taken at least 8 hours apart (but not before going to sleep in the evening). During week 3 to 9 of your treatment you will take a reduced dosage of one 150mg tablet per day.
If you have not successfully stopped smoking by week 7, speak to your doctor. You may need to stop taking Zyban. If you have stopped smoking, you can gradually stop taking Zyban during week 7 - 9. Speak to your doctor to discuss the duration of your treatment.
