WhyQuit

WhyQuit reports that in surveys and scientific studies, more people were found to have successfully quit smoking long term using the cold turkey method than nicotine replacement therapies (NRT). NRT delivers smokeless nicotine to the user through chewing gum, lozenges, patches, and nasal sprays. NRT manufacturers typically tout their products as effective ways to ease nicotine withdrawal symptoms, which, in theory at least, should help smokers to quit. However, the vast majority of NRT users either resume smoking or become as addicted to expensive nicotine gum, patches, and lozenges.

Although no studies have compared cold turkey to Chantix, researchers have studied Chantix against NRT. While one study showed that Chantix appeared to be more effective than NicoDerm CQ in the short term, after a year, the success rate was statistically the same for both Chantix and NRT users. According to WhyQuit, the study forced Pfizer researchers to report that there were “no significant differences” between Chantix and NRT, but Pfizer’s ads do not mention the statistic.

If cold turkey is more effective than Chantix, and NRT is about the same, “why assume Chantix’s long list of serious use risks in exchange for little or no benefit?” WhyQuit asks.

The organization says that without support, “Chantix is probably worthless.” While counseling and support have proven their ability to drastically boost the chances of quitting permanently, Chantix has never been tested as a stand-alone smoking cessation aid. The drug is packaged with a support plan that includes a toll-free number and a web site to which consumers may turn for extra support. Pfizer hasn’t said what percent of Chantix users take advantage of the support program, but if the support seekers were subtracted from the total number of successful Chantix quitters, then the success rate would likely plummet.

Also, if Chantix were as helpful as Pfizer claims, then smoking rate in America ought to be descending. Since Chantix first appeared on the market, however, the adult smoking rate actually increased by one percent.

A third point of contention WhyQuit makes concerns the placebo studies that researchers conducted to gauge the effectiveness of Chantix. “Use of placebo controls in drug addiction studies is license to steal,” WhyQuit says, asserting that test subjects who experience severe withdrawal symptoms certainly know that they’ve been given a placebo rather than a drug that is supposed to mitigate those symptoms. Such studies allow Pfizer to exaggerate the efficacy of Chantix.

Fourthly, WhyQuit calls Pfizer out on its ads displaying people who claim, “I honestly love smoking,” saying that the ads mess with the drug-addicted brains of smokers. Pfizer adds appeal to Chantix by telling consumers that they may continue to smoke through the first week of treatment.

“It isn’t that we loved smoking but that we didn’t like what happened when we didn’t smoke,” WhyQuit claims.

“Drug addiction is about living a lie,” WhyQuit says. A dopamine reward pathway that convinces the addict that “nicotine use defines who they are, gives them their edge, helps them cope and that life without smoked nicotine would be horrible. Pfizer knows this and is now playing upon it.”

Finally, WhyQuit asserts that “what Pfizer will never teach smokers is that cold turkey accounts for far more long-term success stories each year than all other quitting methods combined.” After 3 days of nicotine abstinence, physical withdrawal symptoms dissipate and the brain works to heal its receptors. Counseling and support help cold turkey quitters with the emotional and psychological aspects of quitting smoking.

Carter, who played keyboard and guitar for Edie Brickell & The New Bohemians, was shot and killed by his girlfriend’s neighbor in the predawn hours of September 3, 2007. According to Ryann Rathbone, Albrecht’s girlfriend at the time, the two had spent the evening at a Dallas bar before going back to Rathbone’s home, where they both took their Chantix doses. Shortly afterward, Albrecht began speaking incoherently and acting violently, hitting Rathbone several times.

Rathbone ran out of the house and Albrecht pursued her. She then ran back into the house, closed the door, and locked Albrecht outside, whereupon he began pounding on the door and yelling. He then entered the neighbor’s backyard and began beating on his back door and shouting. Alarmed by the commotion, the neighbor fired what he said he intended to be a warning shot through the front door. The bullet hit Albrecht in the head, killing him instantly.

Both Rathbone and Albrecht’s family and acquaintances said that his behavior on that fatal night was uncharacteristic. Rathbone says that Albrecht’s behavior became increasingly erratic once he started taking Chantix. Autopsy results showed that Albrecht’s blood alcohol level was more than twice the legal driving limit in Texas, yet those who knew him say that his behavior on September 3 was abnormal, even after drinking heavily.

Chantix first became available by prescription in 2006. Awareness of the drug’s potential to cause negative neuropsychiatric events was not well documented at the time of Albrecht’s death. Just a couple of weeks after the deadly incident, a CBS affiliate in Dallas ran a story about Albrecht’s strange behavior called Chantix: Miracle Drug or Dangerous Problem? Two months later, the Food and Drug Adminstration issued an early communication about an ongoing safety review of Chantix, alerting the public that Chantix may be linked to changes in behavior, agitation, depressed mood, suicidal thoughts and actions, and other side effects.

The Food and Drug Administration

The new boxed warning on Chantix labeling will read: “Serious neuropsychiatric events, including, but not limited to depression, suicidal ideation, suicide attempt and completed suicide have been reported in patients taking Chantix.”

Revised warnings state that neuropsychiatric symptoms and suicidality have been found in patients using Chantix. The post-marketing reports include changes in mood (including depression and mania), psychosis, hallucinations, paranoia, delusions, homicidal ideation, hostility, agitation, anxiety and panic, as well as suicidal ideation, suicide attempt, and completed suicide.”

The warnings state that patients should stop taking Chantix immediately if they experience any of the adverse neuropsychiatric symptoms or exhibit changes in thinking and acting that aren’t characteristic of the patient.

The new Chantix warnings also caution that “there have been post-marketing reports of traffic accidents, near-miss incidents in traffic, or other accidental injuries in patients taking Chantix.

The new warnings also advise that “resolution of symptoms after discontinuation of Chantix was reported,” but that the symptoms persisted in some cases.

Warnings for Wellbutrin and Zyban are to carry warnings similar to those for Chantix. “Patients should be observed for neuropsychiatric symptoms including changes in behavior, hostility, agitation, depressed mood, and suicide-related events, including ideation, behavior, and attempted suicide.”

“People who are taking Chantix or Zyban and experience any serious and unusual changes in mood or behavior or who feel like hurting themselves or someone else should stop taking the medicine and call their health care professional right away,” The FDA warns in its latest announcement.

The FDA also urges friends and family members to be observant of those using the medications, watching for behavioral changes in particular. The FDA said observers noticing such changes should “tell the person their concerns and recommend that he or she stop taking the drug and call a health care professional right away.”

Health officials are reluctant to withdraw smoking cessation drugs from the market even if the drugs prove to be dangerous for many people because smoking is the leading cause of preventable death in the U.S. Instead of an outright ban, they recommend taking the drugs with extreme caution.

In addition to boxed warnings on product labeling, the FDA will also require all adverse risks to be described in the drugs’ Medication Guides. The same regulations will also apply to generic versions of Zyban.

According to the FDA, analyses of both Chantix and Zyban users revealed disturbing patterns, noting that while many people stopped experiencing adverse affects once they discontinued the medication, others “continued to have symptoms after stopping the medication. Also, in a few cases, the problems began after the medication was stopped.”

The FDA also said it will require the drug manufacturers to conduct new clinical trials to determine how frequently serious neuropsychiatric symptoms occur in patients undergoing various smoking cessation therapies. To help discern whether the drugs cause the symptoms or merely exacerbate them, the trials will include patients with and without psychiatric disorders.

Chantix is manufactured by New York-based Pfizer Inc. Zyban is manufactured by GlaxoSmithKline, Brentford, Middlesex, United Kingdom.

The decision to turn the volume up on Chantix warnings follows several months of reports linking the drug to a slew of negative side effects. Feeling unusually agitated, depressed, or hostile are some of the effects commonly reported. Sudden changes in behavior, impulsive or disturbing thoughts, and the desire to hurt oneself or others are some of the more serious reactions reported.

In the United States, the Food and Drug Administration received more reports of serious injuries arising from Chantix than for any other drug. Prescription drug related death, which normally accounts for 16 percent of all serious reactions reported to the FDA, soared to 23 percent in the first quarter of 2008, largely because of Chantix. The U.S. has since strengthened warnings on Chantix labels.

Health Canada says that while Chantix can be an effective aide in quitting smoking, users of the drug and their families should closely monitor behavior for any changes. Sudden shifts in mood, depression, aggression, and thoughts of self harm are red flags that everyone should watch for. The person taking Chantix should avoid driving and operating heavy machinery until they know that Chantix does not have any adverse effects on them, Health Canada recommended.

Pfizer’s spokesman in Canada, Christian Marcoux, said that Chantix is safe and that some of the adverse side effects are actually caused by quitting smoking.

For many people, however, (including me), the Chantix experience isn’t one of wild extremes. It’s more like a strange trip through life with a brain that feels somehow different from the brain you had before. You feel normal and behave normally most of the time, but occasionally you find yourself saying or doing something that is not you, and the realization that accompanies this uncharacteristic behavior leaves you feeling disembodied and maybe even a little crazy.

New York magazine recently published an excellent article by a guy who recounts his own journey through a landscape made murky by Chantix. If you are one of the people who are seriously considering taking Chantix but trepidatiously wonder what it will be like for you, read Derek De Koff’s story, which echoes the experiences of so many people in blogland.

De Koff writes, “After a few weeks on Chantix, I had managed to stop smoking altogether—but it didn’t feel like a triumphant turn of events. I’d become rather reclusive, avoiding calls from friends, and basically just shuttling back and forth between my office and my apartment. I began to dread six o’clock; it meant I had to walk through the streets again. The subway was now out of the question; it made me too nervous. I stopped going to the gym, too.

“I wondered whether Chantix was zapping my brain’s pleasure-delivery system to such a degree that not only did I find no reward in cigarettes, but I also found no reward in socializing, exercising, writing, or any of my usual self-stimulating tricks. I’d pace the floor, sit on the bed, channel surf, pace some more, try to read, but the room had a stale, sinking feeling.”

So many people have such enormous expectations of Chantix, but the basic truth is that it may work for you (at least in the short term) and it may not work for you at all. If you decide to use it, monitor your behavior closely. I’m one of the people who took Chantix unsuccessfully. Ultimately it was the power to control my own thoughts that worked for me, bolstered by the fact that I had spent hundreds of dollars on a drug that did nothing but make me feel weird, half crazy, and “out of it” most of the time.

More than 1,000 complications were reported in the first quarter of 2008, including 15 traffic accidents, 52 incidents of loss of consciousness and blackouts, and 50 deaths.

Reports of adverse effects among users taking Chantix were greater than any other prescription drug for the second quarter in a row.

While the drug already urges caution while driving and operating machinery, the new reports suggest a stronger warning may be justified. The Food and Drug Administration is currently reviewing the data to determine if Chantix should carry warnings against driving and operating machinery altogether.

“FDA confirms that there are reports of accidents, including road traffic accidents, after the use of varenicline in the Adverse Event Reporting System. The FDA is reviewing these reports to see if current labeling related to accidents after varenicline is adequate,” said FDA spokesman Christopher DiFrancesco in an email to Reuters.

Earlier this year, the Federal Aviation Administration banned pilots and air traffic controllers from using Chantix. The Federal Motor Carrier Safety Administration also prohibited the use of Chantix.

“It appears that medical examiners should not certify a driver taking Chantix because the medication may adversely affect the driver’s ability to safely operate a commercial motor vehicle,” FMCSA Administrator John H. Hill said in a public statement.

Chantix sales in the U.S. declined more than a third following warnings about dangerous side effects and a subsequent suspension of Pfizer’s advertising campaign. Sales outside of the U.S. rose by 3 percent.

Chantix plays a key role in Pfizer’s financial pipeline as its other blockbuster drug Lipitor will go generic after July 2010.
