Chantix, manufactured by Pfizer, was approved in 2006 and since that time has been prescribed to more than 4 million patients. However, not long after its release, the drug was linked to psychiatric problems including depression, suicidal thoughts and actions, and aggressive behavior. The drug also has been linked to serious physical side effects including heart problems, diabetes and serious allergic reactions such as Stevens Johnson Syndrome.

According to the Stars & Stripes, the drug was removed from the military pharmacy at Yokota Air Base in Japan. The decision came after a May 21 report by the Institute for Safe Medication Practices, which says Chantix has had more serious adverse incident reports in the fourth quarter of 2008 than any other drug in this time period.

In response to the ISMP report, the Federal Aviation Administration banned pilots and air traffic controllers from using the drug. The Stars & Stripes reports that the Defense Department’s Office of the Chief Medical Officer also recommended that “varenicline should not be used by personnel operating aircraft (including aircrew and air traffic controllers) and missile crew members.”

The paper says the DOD safety notice also had recommendations for “vehicle operators, operational personnel, and other DOD personnel” under consideration.

Stars & Stripes says the Yokota base has not reported any adverse reactions to Chantix, but seems to be banning the drug as a precautionary measure, and has suspended refills of Chantix until patients review the drug use with their physician. Other base hospitals overseas have not banned the drug, but air crewmembers cannot take the drug, and other Chantix patients are required to discuss their use of the product with their physician. Pharmacies can special-order the drug based on those prescriptions.

According to the report, when Chantix was first licensed in 2006, it was prescribed 262 times in military treatment facilities. By fiscal year 2007, there were 67,580 prescriptions written for Chantix in military facilities.
