Can I become addicted to varenicline?

Findings suggest that varenicline (Chantix) is not addictive. However, it may be associated with physical dependency. Studies show that stopping varenicline abruptly may result in mood swings, irritability and sleep problems in some people. A doctor will instruct you on how to stop taking varenicline in a way that minimizes any physical withdrawal symptoms.

In clinical trials, fewer than 1 out of 1,000 people taking varenicline claimed having feelings of euphoria. When used in high doses (more than 2 mg per dose), a small percentage of people taking varenicline reported gastrointestinal problems, including vomiting and nausea.
