You should follow your doctor's advice when using Champix.
Once you've bought Champix, set a quit date one-to-two weeks into your treatment. Continue smoking as normal in the first week of treatment because it takes about one week or so for Champix to start working properly. Try not to delay quitting past five weeks into treatment.
Not smoking at all after your quit date gives you the best chance of stopping for good. If you slip up and have a cigarette after your quit date, you may still succeed at quitting if you keep taking your course of Champix and recommit to stopping smoking.
Your doctor will tell you how many tablets you should take. The usual dose is described in the Consumer Medicine Information provided with the Chapix tablets. However, your doctor might decide to reduce the number of tablets you take based on your individual needs.
You should take your tablet at the same time each day. If you forget to take it, take it as soon as you remember. If it is almost time for your next dose, you should just skip the tablet you missed. Do not take a double dose of this medicine.
Champix should be swallowed whole with a full glass of water. It can be taken with or without food. Some people find it helpful to take it with food, as it can help reduce nausea.
You should take Champix for the full 12 weeks of treatment, even if you have stopped smoking.
Do not use nicotine replacement products or Zyban while using Champix.
