Stop Smoking Pill
The Varenicline stop smoking pill (trade names Chantix and Champix) is a prescription quit smoking medicine, in the form of a tablet, that is used to treat nicotine addiction.
How does Varenicline work?
This stop smoking pill "binds to the nicotine receptors in the brain, and blocks them so that nicotine cannot bind to them. The reward of nicotine is reduced because nicotine can no longer stimulate the pleasure center by raising the dopamine level in the brain. This helps reduce cravings for cigarettes. It also seems to help reduce withdrawal symptoms when smokers quit".1
The Varenicline stop smoking pill should be taken whole, after a meal, with a full glass of water.
A single 0.5mg pill is taken for the first three days. Dosage in then doubled for the next four days: one 0.5 mg pill should be taken each morning and each night.
During the second week the dosage is doubled yet again. Typically one 1mg pill is taken each morning and each night. Most people will take CHANTIX for up to 12 weeks. If you have completely quit smoking by 12 weeks, your doctor may prescribe CHANTIX for another 12 weeks to help you stay cigarette-free.2
