what year did the nicotine nasal spray become fda approved
Three types of NRT are approved by FDA for consumers to buy OTC: nicotine gum, transdermal nicotine patch, and nicotine lozenge products. FDA first approved nicotine gum and patches as prescription products between 1984 and 1992. These products were shown to be safe and effective for use when someone first stops using cigarettes, and then uses the NRT to help manage the symptoms of withdrawal, usually for 8-12 weeks depending on the product.
