In 2006, Pfizer’s anti-smoking drug, Chantix, seemed like a godsend to many people addicted to cigarettes. With reported success rates of up to 44 percent, Chantix seemed like the best medicine on the market for those who wanted to stop smoking. However, documentation of dangerous side effects has driven this once promising drug into a questionable realm.

Chantix works by targeting the receptors in the brain susceptible to nicotine and blocks them. But blocking them is only part of Chantix’s charm. It also reduces dopamine levels released when someone is smoking. Reduced levels of dopamine means reduced pleasure derived from smoking.

Side Effects

As with many drugs on the market, there are certain side effects to watch for. However, the side effects experienced by users of Chantix caused a number of groups to issue warnings. The Institute of Safe Medication Practices and the FDA reported as early as the end of 2007 that there were almost a thousand serious injuries in the US that may have been caused by Chantix. This was due to side effects such as:

• Dizziness
• Disturbances in vision
• Fatigue
• Heart rhythm disturbances
• Seizures and muscle spasms
• Severe skin reactions
• Onset of diabetes

There were further reports of nausea, vomiting, constipation, and other gastric issues among users of Chantix. In the 4th quarter of 2007, Chantix topped a list of over 700 drugs with the most serious side effects, yet it was not given a black box warning by the FDA, nor was it considered for a recall.

Psychiatric Risks

While the physical side effects of Chantix were coming in, the most serious problems were beginning to surface. There were reports of changes in dreams, chronic anxiety, feelings of depression and suicidal thoughts when the drug was taken. Psychotic episodes and hallucinations were also documented. People continued to have these problems even after they quit taking Chantix.

Because of these side effects, the Federal Aviation Administration (FAA) sent a letter to pilots and those working in control towers in May 2008, banning them from taking the drug.

Though Chantix may have a fairly successful record of treating people for their smoking addiction, and the number of reported dangerous side effects may seem small, the danger is real. If you are taking Chantix, discuss your concerns with your doctor before you stop taking it.
