Chantix is a drug taken to decrease the desire to smoke. The drug is manufactured by Pfizer and works by blocking receptors to the brain that cause one to appreciate the effects of nicotine. Similar to most prescription medications, there are numerous Chantix side effects that users should be aware of before taking the drug. Some of the most common Chantix side effects include nausea, insomnia, headaches, gas, and constipation. More severe Chantix side effects include depression, thoughts of suicide and psychological effects.

Under-Reporting of Chantix Side Effects

A recent study suggests that the more serious Chantix side effects, which include depression, sudden violent behavior, seizures, psychosis, and psychosis along with suicidal thoughts, have been under-reported by Pfizer. On June 1, 2011, the Institute for Safe Medication Practices reported that “there were 150 instances where users of the smoking-cessation drug Chantix committed suicide out of the nearly 600 delayed reports of severe issues noted in the study.” In response to these findings, the Food and Drug Administration (“FDA”) requested that Pfizer resubmit thousands of records in order to gain a more vivid picture of just how pervasive and severe Chantix side effects really are after long-term use. A March 2007 study, published in the medical journal, Current Medical Research and Opinion, which included only 251 people who took Chantix for at least a full year, concluded that the data collected from this small sample would likely not find serious Chantix side effects because of the small sample size. Despite the findings, the study concluded that Chantix should not be used for a prolonged period of time. Pfizer disagreed with the study and determined that based on the sample size and a finding of no serious side effects, Chantix is safe for long-term use. As of today, the FDA has yet to clear Chantix for long-term use. The drug’s label indicates Chantix should be used for no longer than 12 weeks. If after 12 weeks a Chantix user has not stopped smoking, they should ask their doctor if an additional 12 week period would be beneficial.
