The nicotine patch is an effective aid for smoking cessation. Since 1996, the nicotine patch has been re-classified from prescription to over-the-counter (OTC) status in the United States. Unlike prescription medications, post-marketing surveillance does not exist for OTC medications. The purpose of this study is to describe the characteristics of consumers who purchase OTC nicotine patches from community pharmacies and to determine the factors associated with appropriate use of nicotine patches.
