To use Nicorette Lozenges, place one in your mouth and allow it to slowly dissolve. Occasionally move the lozenge from one side of your mouth to the other. Do not chew or swallow the lozenge. Repeat this process until the lozenge dissolves completely, which should take about 10-20 minutes. You can have a lozenge whenever you feel the urge to smoke. Over time, you may need fewer lozenges to control your nicotine cravings and withdrawal symptoms.
