nicotine nasal spray, a product approved by the U.S. Food and Drug Administration for aiding tobacco smoking cessation in adults; not available in Canada. One dose of the nasal spray administers 1 mg of nicotine directly into the nasal membranes. Because of the risk of becoming dependent on the nasal spray, it is recommended that patients not use it for more than 6 months. See also nicotine replacement therapy.
