How Chantix Works
Chantix works in two ways to help you stop smoking. It works to
block the effects of nicotine, reducing the pleasure reward of
smoking. And it provides some nicotine effects to ease the
severity of cravings and withdrawal symptoms. This dual action
makes it easier for many patients to stop smoking.
Advantage of Chantix
Like Zyban, Chantix does not contain nicotine so patients can
take Chantix while using nicotine replacement products like gum
and patches to help them stop smoking. Independent studies have
shown that Chantix helped more people stop smoking than Zyban
(44% with Chantix vs. 30% with Zyban).
How to Take Chantix
Choose a quit date when you will stop smoking. Then start taking
Chantix 7 days before your quit date. This lets Chantix build up
in your system. You begin by taking one tablet a day for three
days, then increase to two a day until treatment is over. You
can keep smoking during this time. Make sure you try to stop
smoking on your quit date. If you slip, try again. Some people
need a few weeks for Chantix to work. Most people will keep
taking Chantix for up to 12 weeks. Take Chantix after eating and
with a full glass of water.
Chantix Side Effects
The most common side effects of Chantix are nausea, changes in
dreaming, constipation, gas and vomiting. If any of these
effects persist or worsen, notify your doctor promptly. A
serious allergic reaction to Chantix is unlikely, but seek
immediate medical attention if it occurs. Symptoms of a serious
allergic reaction include: rash, itching, swelling, dizziness,
trouble breathing. If you notice other effects not listed above,
contact your doctor or pharmacist.
Chantix Precautions
Tell your doctor about all of your medical conditions including
if you have kidney problems or need kidney dialysis. Your doctor
may prescribe a lower dose of Chantix if you are pregnant or
plan to become pregnant. Chantix has not been studied in
pregnant women and it is not known if Chantix will harm your
unborn baby. Although it was not studied, Chantix may pass into
breast milk.
Drug Interactions
Tell your doctor of all prescription and nonprescription
medication you use, especially: insulin, asthma medicines, and
blood thinners. When you stop smoking, there may be a change in
how these and other medicines work for you. Do not start or stop
any medicine without doctor or pharmacist approval.
