How does Champix work?
Varenicline is a prescription drug which is used for treating nicotine addiction, and is applied for the cessation of the smoking of cigarettes, and other products made from tobacco. It helps adults who want to quit smoking by reducing cravings and pleasurable effects of tobacco products.
Champix Tablets work by competitive binding. There are nicotine receptors in the brain, and when tobacco or cigarette smoke is inhaled the nicotine in the cigarette, smoke binds itself or attaches itself to thenicotine receptors in the brain. This transmitsanelectrical signal to another section of the brain, anddopaminethat is responsible for creatingfeelings of thrill and titillation is released.
But this feeling only lasts a short while. The body wants to repeat this feeling, soit reinforces the need to keep smoking. This is why many struggles to quit is that nicotine. When you do decide to quit smoking, you start to get withdrawal symptoms soon after your last smoke.
Varenicline works by binding itself to these same nicotine receptors, and hence blocking nicotine from attaching to them. Varenicline partly stimulates the nicotine receptors to mimic the action of nicotine. This reduces cravings and the withdrawal effects usually experienced when you stop smoking.
While mimicking the effects of nicotine, it also partly blocks the nicotine receptors, thus preventing nicotine from attachment to the receptors. Bythis action, the impact of nicotine becomes blunt and withdrawal symptoms become less intense. Champix does not contain nicotine, and neither it is it addictive.
Are there Any Side Effects with Champix?
It is strongly advised that you study the detailed information printed in the leaflet that accompanies the medicine for a complete list of all the possible side-effects and cautions about the use of Champix. However, most people who take Varenicline do not develop any side-effects, or even if they do, they are mostly the only minor.
The side effects to be discussed do not happen often. However, if you do not speak to your doctor when the symptoms occur and become persistent, it may lead to more serious problems in the future. Remember that Varenicline is strictly a prescription drug, and should therefore be taken under the guidance of a trained medical doctor.

You might feel as if you will not be able to live without the cigarette or tobacco products. That is normal and will not just disappear at the instant that Champix is introduced into the system. But all of this will wear away eventually, and medication should be administered under the strict supervision of a certified doctor.
