The 3 Week Diet

A: Up to one third of the study participants complained of either nausea or vomiting while using Champix (or Chantix).*

On September 2006, Pfizer issued a press release announcing European Commission approval of Champix, its new quit smoking pill. It boasts that “after one year, approximately one-in-five patients who received the 12-week course of varenicline [Champix] remained smoke-free.”

Smoking is a chronic relapsing medical condition that typically involves a physical and psychological addiction to nicotine.

In Europe alone, more than 1.2 million people die each year from smoking-related diseases. In addition to the human toll, there is a significant social and economic cost associated with smoking.

By 2010, the World Health Organization predicts the annual global cost of tobacco-related illness will be approximately $500 billion, with Europe accounting for up to $165 billion of this sum.

How Champix works?


By reducing the smoker’s craving for nicotine by binding to receptors in the brain and reduces the symptoms of withdrawal. And it reduces the satisfaction a smoker receives when smoking a cigarette.


Clinical trials to date have shown that Champix is more effective than currently available oral antismoking prescription medicines.

In trials, 44% of the group treated with Champix had stopped smoking after being treated for 12 weeks, as opposed to 11% of smokers taking the placebo.

Over the same duration, it was also shown to be twice as effective as Zyban (bupropion), the other main anti-smoking drug treatment.

What is the most important information I should know about Chantix?

You should probably try other quit smoking methods first before Chantix. Because Chantix has been linked with depression and suicide.

Use this medication exactly as it was prescribed for you. Do not use it in larger amounts or for longer than recommended by your doctor. Follow the directions on your prescription label.

If you miss a dose, use the medication as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regularly scheduled dose. Do not use extra medicine to make up the missed dose.

“I was a heavy smoker, and quitting was the most difficult personal challenge I ever faced. After I quit, I worked with a team of Pfizer scientist to develop Chantix specifically to help smokers quit.” -Dr. Jotham Coe, Pfizer scientist.

What is the most common side effect experienced while
taking Chantix or varenicline? It all depends on how you
look at it. If you surf online the answer might appear to be
nausea. Nausea is reported in about 30% of people taking
this drug.

However, sleep disturbance is much more common.
Especially if you add all the side effects having to do with
sleeping:

Insomnia 18%
Abnormal dreams 13%
Sleep disorder 5%
Somnolence 3%
Nightmares 1%
___
Total 40%


However the wild dreams cause by Chantix was actually
enjoyed by some people. So maybe its a benefit and not
a side effect per say.
