Full glass of water. The daily dose increases over the first 8 days you take it. If you have problems with the higher doses, a lower dose may be used while you try to quit. Typically, varenicline is given for 12 weeks, but people who quit during that time may get another 12 weeks of treatment to boost their chances of staying off tobacco. It’s important to keep up with other support systems during this time and for at least a few months after quitting. Before you start varenicline, tell your provider about any medical conditions and allergies you have, including if you have kidney problems or might be pregnant. Side effects of varenicline Reported side effects of varenicline include: Nausea or vomiting Headache Trouble sleeping, vivid dreams, or sleepwalking Constipation Gas and diarrhea Changes in taste Skin rashes Heart or blood vessel problems (mostly in people who already have these problems) Mood or behavior changes such as depression, hallucinations, delusions, aggression, hostility, agitation, anxiety, panic, or suicidal thoughts Ask your health care team about what to expect while taking this medicine, and what to do if you have side effects. Be sure to let your provider know if you’ve ever had depression or other mental health problems, or if you start feeling depressed or have thoughts about suicide while taking varenicline. Be careful driving or using heavy machinery as varenicline causes some people to feel sleepy or dizzy. Using varenicline along with NRT (nicotine patch) or bupropion Using varenicline along with the nicotine patch has shown better outcomes than using varenicline alone. More people quit tobacco with this combination, and side effects appear to be about the same. Studies are also looking at the use of varenicline and bupropion (another FDA-approved medicine, see below) together for quitting tobacco. This combination is not usually suggested right away, but it may benefit people who need more help when one medicine isn’t enough. While there may be a benefit to combining the medicines, more research is needed to better understand the side effects that can happen when doing so. Bupropion (Zyban) Bupropion
