Nicotine-agonists are used to help you quit smoking, manage nicotine withdrawal symptoms, and reduce cravings. They also have other uses, such as aiding in smoking cessation programs and reducing the risk of returning to smoking. These medications work by stimulating the same receptors in your brain that nicotine does, which helps to reduce withdrawal symptoms and cravings. Nicotine-agonists come in different forms, including oral pills, patches, and gums. Examples include varenicline (formerly Chantix), nicotine lozenges and gum (Nicorette), and nicotine patches (Nicoderm CQ, Habitrol). You can choose the form that best fits your needs.
