How long should I take Champix for?
A course of Champix treatment usually lasts 12 weeks. During this period, you will gradually increase the dosage according to a specific schedule indicated in the instructions for the medicine. It is important to strictly follow this schedule to achieve the best results.
It is important to set a quit date within the first two weeks of starting Champix treatment. This date will mark the beginning of your smoke-free journey. However, it is important to note that smoking cessation may be delayed in some people until the 12th week of treatment.
Champix blocks nicotine receptors in the brain, reducing the pleasure of smoking and minimizing nicotine withdrawal symptoms. It helps relieve cravings and makes quitting smoking more manageable. However, quitting smoking is a complex process and Champix should be used as part of a comprehensive smoking cessation program that includes behavioral support and counseling.
Is Champix more effective than other products for smoking cessation?
Many studies have been conducted to compare the effectiveness of Champix with other smoking cessation products, such as nicotine replacement therapy (NRT) or bupropion. Overall, the results have shown that Champix is indeed more effective in helping individuals quit smoking compared to these alternatives.
One study published in the Cochrane Database of Systematic Reviews analyzed several trials involving over 8,000 smokers. The results showed that Champix increased the likelihood of quitting smoking compared to placebo, NRT, or bupropion. Another study published in the New England Journal of Medicine found that after 12 weeks of treatment, Champix had a higher abstinence rate compared to a placebo.
