What is a nicotine replacement patch used for?

The patch supplies nicotine without the smoke and many harmful chemicals produced by burning tobacco. It can reduce cravings, irritability, restlessness and difficulty concentrating while you change smoking habits.

A patch does not remove every urge to smoke. A structured smoking cessation programme can add practical support, help identify triggers and guide use of other nicotine replacement products when appropriate.

Apply the patch to clean, dry, intact skin in the way shown on the product instructions. Rotate application sites and wash your hands afterwards. Follow the prescribed strength and schedule; do not cut a patch or wear extra patches unless a clinician tells you to.

Remove the old patch before applying a new one, and fold used patches sticky-side together before disposal. Avoid smoking while using nicotine replacement unless a healthcare professional has given you a specific plan, because too much nicotine can cause symptoms.

Get urgent help for severe nausea, vomiting, dizziness, weakness, confusion, breathing difficulty or a very fast or irregular heartbeat after using nicotine. Seek advice for a persistent rash, swelling, sleep disturbance or vivid dreams that make treatment difficult.

Ask which patch strength and schedule fit your smoking pattern, whether another nicotine product could help with sudden cravings, and how pregnancy, heart problems or other medicines affect your options.
