Nicotine Gum Fact Sheet

Description of Product:
Nicotine gum is chewed to release nicotine that is absorbed through the skin inside the mouth. The user chews the gum until it produces a tingling feeling, then the gum is placed (parked) between the cheek and gum tissue. Nicotine gums have varied amounts of nicotine (typically 2 mg or 4 mg) to allow users to reduce the amount of nicotine in their body.
Nicotine gum (both regular and flavored) is available in 2 mg and 4 mg (per piece) doses. The 2 mg gum is recommended for individuals smoking fewer than 25 cigarettes a day. The 4 mg gum is recommended for individuals smoking 25 or more cigarettes a day. Smokers should use at least one piece of gum every 1 to 2 hours for the first 6 weeks. Recommended duration of therapy is up to 3 months. No more than 24 pieces of gum should be used per day.
Side Effects:
Side effects may include:
  • Hiccups
