About Champix Champix is licensed for use as a prescription only medicine for smoking cessation. By far, it is one of the most successful drugs available for smoking cessation. In clinical trials, Champix has proven to be the most effective in helping people quit smoking for life as compared to any other smoking cessation treatment or medication, including the only other FDA approved medication, Zyban (bupropion). In a 12-week clinical study, there was a 44% success rate amongst people trying to quit smoking with the help of Champix as against 33% success rate amongst people using Zyban.
Even though Champix is proven to be highly effective as a smoking cessation medication, it lays no claim to being a miracle drug. The medicine works only in people who are determined to quit smoking and are ready to use Champix as an aid to boost their quit smoking efforts. Further, Champix is recommended for use in conjunction with professional counselling.
How does Champix work? The active ingredient in Champix is called varenicline. It belongs to a class of medicines called nicotine receptor antagonist. Champix varenicline mimics the effect of nicotine on the brain. It attaches itself to the same receptors in the brain as used by nicotine. This action dupes the brain into believing that it has received its required dose of nicotine. A person does not experience cravings for nicotine and is thereby relieved of the anguish caused by withdrawal symptoms.
Another unique feature that makes Champix different and better than any other smoking cessation treatment is that it reduces the pleasure a person derives from smoking. Champix varenicline makes this possible by blocking the nicotine from acting on its receptors in the brain. Even if a person smokes during the course of the treatment, he/she will not derive the same pleasure from smoking and will therefore have no desire to smoke again. This feature of Champix helps people in succeeding in their quit smoking mission.
Dosages of Champix Champix treatment is usually recommended for a 12-week period. However, your doctor may suggest that you begin the treatment a week in advance of your quit date. During this week, you will be asked to take lower strength dosages (0.5mg) of Champix - once a day for 3 days and twice a day for the next 4 days. This is done to help your body get adjusted to the medicine; you may continue to smoke during this week. Following this week, you'll need to take Champix 1mg tablet twice a day for 12-weeks. You need to take the medicine with a full glass of water at the same time each day, preferably after meals.
Side effects of Champix Like most other prescription medications, Champix varenicline is associated with certain side effects. However, most side effects of Champix are mild to moderate and may not affect all individuals. Common side effects of Champix include nausea, headache, difficulty sleeping and abnormal dreams. Other less common Champix side effects include sleepiness or fatigue; dizziness; change in taste and dry mouth; disturbances of the gut such as constipation, diarrhoea, vomiting, abdominal discomfort or bloating; indigestion, wind or increased appetite.
In rare cases, Champix is reported to have caused changes in behaviour, agitation, depressed mood and suicidal thoughts. Inform your doctor if you experience any of these rare Champix side effects or if any of its side effects become bothersome.
