What to remember when taking CHANTIX.

  • Some people have had changes in behavior, hostility, agitation, depressed mood, suicidal thoughts or actions while using CHANTIX to help them quit smoking. Some people had these symptoms when they began taking CHANTIX, and others developed them after several weeks of treatment or after stopping CHANTIX. If you, your family, or caregiver notice agitation, hostility, depression, or changes in behavior, thinking, or mood that are not typical for you, or you develop suicidal thoughts or actions, anxiety, panic, aggression, anger, mania, abnormal sensations, hallucinations, paranoia, or confusion, stop taking CHANTIX and call your doctor right away. Also tell your doctor about any history of depression or other mental health problems before taking CHANTIX, as these symptoms may worsen while taking CHANTIX.
  • Before starting CHANTIX, tell your doctor if you have a history of heart or blood vessel problems. If you have new or worse heart or blood vessel symptoms during treatment, tell your doctor. Get emergency medical help right away if you have any symptoms of a heart attack or stroke.
  • CHANTIX should be taken after eating and with a full glass (8 ounces) of water.
  • If you miss a dose, take it as soon as you remember. If it's close to the time of your next dose, wait. Then just take your next regular dose.
  • If you slip up and smoke while taking CHANTIX, don't give up. Keep trying to quit and keep taking CHANTIX. Some people need a few weeks for it to work best. In studies, some people who smoked after their Quit Date were able to quit successfully.
  • Even if you successfully quit smoking in the first few weeks of your CHANTIX treatment, remember that CHANTIX is recommended for the full 12 weeks. In studies, 44% of people who took CHANTIX were quit during weeks 9 to 12 of treatment (compared 18% on sugar pill).
