NiQuitin lozenges are a drug that delivers therapeutic nicotine to the body, supporting smoking cessation while alleviating nicotine withdrawal symptoms. Unlike tobacco, NiQuitin does not contain harmful tar, carbon monoxide or other chemical compounds that adversely affect health. The drug is intended for use as part of nicotine replacement therapy and contains strictly controlled amounts of therapeutic nicotine, which relieves nicotine cravings and withdrawal symptoms, making it easier to quit smoking. Whenever possible, when quitting smoking, NiQuitin should be used in conjunction with a psychological cessation program.

NiQuitin in the form of mint-flavored lozenges with a dose of 4 mg of nicotine is intended for people who smoke their first cigarette within 30 minutes of waking up.
