I’ve heard there can be serious side effects of using Varenicline (Champix®), such as becoming depressed and mentally unwell. Is this true?
All medicines can have side effects. Sometimes these side effects are serious and some may even require medical attention, but most of the time they aren’t a cause for concern.

Do I only need one script for Varenicline (Champix®)?
No, the first script provides you with four weeks’ worth of medication. You’ll need to return to your GP for a review after 2-3 weeks of starting Varenicline (Champix®), before being prescribed the remainder of the course.
I’ve heard that I have to enrol or join a support program to get Varenicline (Champix®) – is this true? What happens if I don’t want to?
Yes, this is correct. A condition of being prescribed this medication is that you receive professional quit smoking support at the same time, such as the NSW Quitline. The evidence suggests that if you undertake both of these, you will have a better chance of quitting. Your GP can provide further guidance on support programs.
