Champix® Varenicline

TOSS can provide you with advice and guidance on the use of Champix®. Champix® is proven to be an effective stop smoking medicine available by prescription from your GP.

What is it?

Champix® is a highly effective medicine to support you to quit smoking.  Champix® is only available on prescription so you will need to make an appointment with your GP. It is not suitable for everyone so your GP will check to make sure that it is right for you.

How does it work?

Champix® works by reducing the urge to smoke, and other withdrawal symptoms, that many people experience when stopping smoking. In doing so it makes your quit attempt easier and will increase your chances of success. However, like all other stop smoking medicines it is not a magic cure.

How do I take the medicine?

Champix® is easy to take and you essentially follow the instructions on the packet. You will need to start this at least one week before your Quit Date, as it needs some time to start working. You can smoke as normal right up until your Quit Date and then aim not to have a single puff afterwards.

It is best that you use the whole 12-week course of Champix® and not stop using it too soon.

Who should not take the medicine?

  • Champix® should not be used by people who have experienced an allergic reaction to it.

  • Those who are under 18 years of age.

  • Pregnant and breastfeeding women.

What are the side effects?

Champix® is associated with some common side effects including nausea, insomnia, and vivid dreams. These are mostly mild and should disappear over time. Make sure you take your tablets with food, as this will limit the nausea.

There are some serious side effects, such as a severe allergic reaction, however, this is uncommon.
