Champix is given to help you quit smoking. But there are things which you should do before you start treatment. This will work with Champix to make sure you have the best possible chance of quitting long term. These are:

  • Inform all friends and family that you are going to be quitting smoking. Get them on board to help and support you when you need it. There will be times you feel like giving up and smoking, this is when you need their support the most. Verbal reassurance from people that care is often what we need to hear to help.

  • Avoid situations and places which may cause you to relapse. These include going to places where you know people will be smoking. Nobody is saying you have to give up your social life.

  • It may be best to avoid the pub and other places where you are used to going for social smoking. Avoiding things like stressful arguments to name a few triggers.

  • Sit down with your Dr and take in all the information and advice that you receive from your doctor.

  • Create a quit plan. Clear away all household items that you use for smoking, lighters and ashtrays.

How does Champix work to help quit smoking

Champix is usually given by prescription as a 12-week course. In your 1st week of usage, the cigarettes will taste strange, this makes it easier to stop smoking. You initially still get the cravings once smoking has stopped, but these steadily reduce and you are less likely to get the withdrawal symptoms.

Champix also works in a very similar way as nicotine by stimulating the same area of the brain that nicotine does. this gives the ex-smoker the mild feeling of a cigarette and prevents you from the need to smoke.

Less common side effects are stomach related problems such as constipation, indigestion and headaches. These usually fade after the first week.

The actual risk of side effects is quite low, always make sure you read the advice in the leaflet in the packet,

Some people have reported mood swings and aggressive behaviour if you experience any symptoms stop taking Champix and speak to your Dr.

It is especially important to let family members know that you are taking Champix and ask them to keep an eye out for any unusual behaviour or changes in mood.
