Overview
Several medicines can help you quit using tobacco. You can take medicine to reduce your craving for nicotine. You also can use nicotine replacement products to reduce cravings and give you smaller and smaller amounts of nicotine.
Your doctor can help you decide which medicine—or combination of medicines—may work better for you. If you have health problems or are pregnant, you may not be able to use some of these medicines.
