Chantix™ (varenicline tartrate) is a medication used to help people quit smoking. It works by blocking some of the pleasurable effects of smoking and decreasing the effects of nicotine withdrawal. This medicine comes in tablet form and is taken once or twice a day for 12 weeks.
Prior to beginning treatment with Chantix, information on the drug's safety warnings and precautions should be reviewed. For example, side effects such as insomnia, abnormal dreams, nausea, and headache are possible. In addition, people who have mental illness or who have exhibited suicidal behavior may need to consider a different medication.
