What is Champix?

Champix is a medicine that can help you quit smoking by tricking your body into thinking its nicotine craving is being fulfilled.

How does Champix work?

Champix contains the active ingredient varenicline. This chemical acts in the brain and is a nicotinic acetylcholine receptor partial agonist. What this means is that it acts on the same receptors in the brain as nicotine from cigarettes does. The varenicline stimulates the nicotinic receptors just as nicotine would. This means, that your cravings for and withdrawal symptoms from nicotine are relieved. In addition, varenicline prevents nicotine from acting on the nicotinic receptors. This results in any pleasant, enjoyable effects from nicotine when you smoke are removed, considerably reducing your cravings.

What other options are there?

Very often it is difficult to quit smoking without any assistance. Champix has been proven to work very well. You can also purchase many forms of nicotine substitutes from pharmacies such as nicotine patches, nicotine sprays and nicotine gum, all of which fulfil your nicotine cravings without you needing to smoke. Sometimes, people smoke to relieve their stress. Dealing with the underlying problems which cause you to smoke may help you quit. If you feel this applies to you, you can speak to a counsellor.

Do I need to change my diet?

There is no need to change your diet. In addition, there are no particular foods you need to avoid.

Can I smoke whilst taking Champix tablets?

Smoking whilst on treatment will not harm the body. However, since you are trying to quit smoking, you must avoid the urge to smoke if you want to effectively quit in the long term.

How effective is Champix stop smoking medication?

It is almost impossible to put an exact figure on this as it will depend on the individual and how much they have previously smoked and how addicted they are. However, Champix is one of the most effective treatments out there according to a wide range of various scientific studies.

Can I use nicotine replacement therapy at the same time?

No, as the two treatments may interact and prevent effective treatment.

Do I need a prescription for Champix stop smoking medication?

Yes, you can get this online at DrEd.

What do the tablets look like?

The 0.5mg tablets are white and biconvex. The 1mg tablets are light blue and biconvex. The tablets are marked on one side with “Pfizer” and on the other with “CHX” and the dosage.

How do I take Champix?

Before starting your treatment, you need to decide a quit date in the second week of your treatment when you will stop smoking. The treatment will only be effective if you are motivated to quit.

Between days 1 and 3, you need to take one 0.5mg Champix tablet once a day. During days 4 to 7, you need to take one 0.5mg Champix tablet twice per day, once in the evening and once in the morning. During week 2 (days 8 to 14) you should take a 1mg Champix tablet twice per day, once in the evening and once in the morning. You should continue this up until week 12 (or for as long as your doctor recommends). If you experience any adverse effects, you should inform your doctor who may reduce your dosage slightly.

You should swallow the tablet whole with water and you can take it with or without food.

People with kidney problems may need a lower dose.

If you overdose, seek medical assistance immediately

If you forget to take Champix, take it as soon as you remember. However, if it is near the time of your next treatment, skip the missed treatment. It is important to get into a routine so that you don’t forget any of your tablets. It may help if you take your treatment at the same time each day.

What does each Champix tablet contain?

The active ingredient is varenicline (as tartrate). 0.5mg tablets contain 0.5mg of varenicline and 1mg tablets contain 1mg of varenicline. The tablets also contain Microcrystalline Cellulose, Calcium Hydrogen Phosphate Anhydrous, Croscarmellose Sodium, Colloidal Anhydrous Silica, Magnesium Stearate, Hypromellose, Titanium Dioxide (E171), Macrogols and Triacetin.
