Use medications to help you
There’s a choice of two prescription medications to help you quit smoking: bupropion (Zyban) and varenicline (Champix). They are not addictive and work by decreasing cravings, although doctors are not sure how they do this, but both medications significantly increase your chances of quitting and staying smoke free. Varenicline is taken for at least 12 weeks and the commonest side effect is nausea (it can’t be used by pregnant women, but they can use nicotine-replacement therapy). Bupropion is taken for at least seven weeks and the commonest side effect is headache. It is not suitable for anyone who has had a seizure (fit) or is at risk of seizures. Before prescribing either medication, your doctor will need to know your full health history and your regular medications.
