If you are a light or a heavy smoker but are determined to quit, Nicorette Microtab can help control your cravings and withdrawal symptoms so you can quit once and for all. The 2mg Nicotine tablet is simply placed under your tongue when you have a craving for a cigarette. Do not suck, chew, or swallow the Nicorette Microtab, just allow it to melt under your tongue. The Nicotine will enter your bloodstream and make its way to your brain in 7-10 seconds and triggers chemical reactions that make you feel good and your cravings disappear temporarily. Nicorette Microtabs can be taken 2 per hour/40 tabs per day maximum until you have the cravings under control. There is no Rx required for Nicorette Microtabs.
