You must visit your physician before commencing treatment with Bupropion. There is a possibility that you will be instructed to take 150mg per day for the initial 3 days of treatment. After
this, your physician may increase your dosage to 300mg per day (in 2 doses). It is important to allow at least 8 hours between doses. Your physician will also tell you how long you need to continue
treatment for. Generally speaking, physicians do not recommend treatment for a period greater than 7 to 12 weeks, and if no success has been met with, you may be told to stop treatment. If you manage
to successfully stop smoking, you may be instructed by your physician to continue treatment for a longer period of time.
