Chantix Side Effects

While most Chantix side effects are mild, there is new information linking chantix to more serious side effects

Chantix, like every drug on the market today, has side effects. You must consider all the facts in order to make an informed decision. Only after careful consideration and discussion with your doctor will you be able to determine if the potential benefit outweighs the risks.

The FDA recently announced that “it appears increasingly likely that there is an association between Chantix and serious neuropsychiatric symptoms.” The FDA report also stated that product label warnings need to note that Chantix should not be used while driving, piloting airplanes or operating machinery because it may cause unconsciousness, seizures and hallucinations. Because of this, the FAA has banned Chantix from use by pilots and air traffic controllers.

The FDA received more accounts of serious side effects tied to Chantix in the fourth quarter of 2007 than from any other drug.

On February 1, 2008, the FDA issued an Alert to clarify its findings, noting that “it appears increasingly likely that there is an association between Chantix and serious neuropsychiatric symptoms.” The FDA report said product label warnings need to note the medication shouldn’t be used while driving, piloting airplanes or operating machinery because it may cause unconsciousness, seizures and hallucinations.

Among the psychological side effects reported to the FDA were 525 reports of hostility or aggression, 397 cases of possible psychosis, 224 reports of heart trouble, 41 cases of homicidal thinking and 28 suicides. There were also 173 serious injuries, including traffic accidents often associated with unconsciousness, dizziness, muscle spasms, or mental confusion, as well as reports of severe skin conditions in patients.

In May 2008 the Institute for Safe Medication Practices issued a report detailing Chantix adverse event reports to the FDA. The study specifically cited 224 reports of potential heart-rhythm disturbances, 372 reports of possible movement disorders and 544 reports of likely glycemic problems, including diabetes. There were also reports of traffic accidents and falls linked to Chantix.
