Chantix’s safety issues and side effects

Chantix is ​​the popular brand name for the drug varenicline, a smoking cessation aid. Chantix is ​​produced by Pfizer Pharmaceuticals. The role of this drug is to prevent the brain from the pleasure of nicotine, thereby eliminating the “pleasure” effect of smoking.

Chantix is ​​only available by prescription, so you must consult a doctor before taking it. It is usually taken in tablet form once or twice a day. However, it is important to note that some serious concerns about Chantix’s side effects-involving changes in mood and behavior-have surfaced.

How Chantix works

When you smoke, nicotine targets receptors in the brain and then produces dopamine, also known as the “feel good” hormone. Dopamine produces pleasant sensations, so people may continue to smoke to feel these effects.

Chantix works by targeting these same receptors in the brain, blocking nicotine and its effects. The idea is that if a person no longer feels the pleasure of smoking, they are less likely to continue smoking.

Chantix can also reduce the urge to smoke. However, it is recommended that you use Chantix in combination with other smoking cessation methods, such as participating in a support group to quit smoking.

According to the manufacturer’s instructions, you start taking Chantix one week before the quit date and continue taking it for 12 weeks. After that, if you feel that you need an additional 12 weeks of treatment, you can discuss it with your doctor.
