  • Nicotine gum. Nicotine chewing gum is a nicotine-releasing gum available over the counter that helps reduce withdrawal symptoms.
  • Nicotine patch. A nicotine patch is an over-the counter patch that can be applied once daily to the upper part of the body to release a constant dose of nicotine. This helps reduce the desire to smoke.
  • Inhaler or nasal spray containing nicotine. Prescription nicotine replacement products that release nicotine to reduce withdrawal symptoms.
