What is Champix and how does it work?

Champix is a plant-based nicotine-free medication that can help adults quit smoking.

Its active ingredient, varenicline tartrate, is non-addictive and works to relieve your nicotine cravings and withdrawal symptoms associated with quitting smoking.

When you smoke, the nicotine from the cigarette targets the nicotinic receptor in the brain and releases dopamine - a short-term pleasure neurotransmitter.

When you smoke a cigarette while taking Champix, the treatment blocks the nicotine from reaching the nicotine-receptor, reducing the enjoyment gained from smoking.

How do I use Champix?

• You should start the treatment about 1-2 weeks before the date you have set to stop smoking.
• Take Champix tablets with water at a starting dose of 0.5mg once daily for 3 days, followed by twice daily for 4 days.
• After a week, take 1mg twice daily for 11 weeks.
• You should continue to take Champix for 12 weeks.

For those who have successfully stopped smoking after the 12 week course of treatment, they should take a follow up course for another 12 weeks:

• 1mg dose twice daily to maintain abstinence.
• Total treatment time should be 24 weeks.
• Take the pills at the same time everyday and if you forget a dose, do not take a double dose to make up for it.

Champix can be taken with or without food, but you need willpower and motivation to stop smoking.

You may feel some of the following side effects after stopping the treatment:

• Irritation
• Urge to smoke
• Slight depression

In that case, you can slowly stop taking Champix rather than stopping abruptly.

Since Champix may make you dizzy or drowsy, be careful when driving.

• Nause
• Headache
• Sleeplessness Difficulty concentration
• Decreased heart rate
• Increased appetite or weight gain

Champix may also produce dizziness and sleepiness.
