Nicotine Replacement Therapy

Key Points

  • Nicotine replacement therapy (NRT) acts as a nicotinic receptor agonist to reduce nicotine-withdrawal symptoms during smoking cessation.
  • Nicotine patches are used as part of a comprehensive behavioral cessation program, not as stand-alone treatment.
  • Apply one new patch every 24 hours to clean, dry, hairless skin and rotate sites daily.
  • Do not use multiple nicotine products simultaneously unless specifically directed, because additive nicotine exposure can cause toxicity.
  • Common concerns include skin irritation and sleep disturbance/vivid dreams; severe symptoms require immediate escalation.
  • Used patches remain hazardous and must be disposed safely away from children and pets.

Mechanism of Action

Nicotine binds nicotinic acetylcholine receptors and partially substitutes for nicotine delivered by tobacco use. This reduces withdrawal burden and supports quit attempts while behavioral interventions are implemented.

Indications

  • Smoking cessation support.
  • Relief of nicotine-withdrawal symptoms in structured cessation plans.

Nursing Considerations

  • Handle as a hazardous medication product and follow safe handling/disposal precautions.
  • Confirm there is no known adhesive allergy before patch application.
  • Apply one patch every 24 hours at the same time each day; rotate application site.
  • Never apply more than one patch at a time unless specifically prescribed.
  • If vivid dreams or sleep disruption occur, remove at bedtime and apply a new patch in the morning.
  • Reinforce complete smoking cessation during NRT to prevent additive nicotine toxicity.
  • Keep all nicotine products, including used patches, out of reach of children and pets.

Patch Administration and Disposal

  1. Select clean, dry, hairless skin.
  2. Remove patch backing and press firmly for about 10 seconds.
  3. Wash hands after application or removal.
  4. Remove old patch before placing a new patch at a different site.
  5. Fold removed patch with adhesive sides together and place in pouch for disposal.

Adverse Effects and Escalation Triggers

  • Common: local skin sensitivity, vivid dreams, sleep disturbance.
  • Urgent:
    • Allergic reaction (for example rash, breathing difficulty).
    • Nicotine-overdose symptoms (nausea, vomiting, dizziness, weakness, rapid heartbeat/palpitations).

Use Cautions

Use with additional risk assessment in clients with:

  • Recent myocardial infarction.
  • Serious dysrhythmias.
  • Coronary artery disease or severe/worsening angina.
  • Uncontrolled hypertension.
  • Vasospastic or peripheral vascular disease.
  • Pregnancy (fetal-risk concerns).

Lower dosing may be required with concurrent monoamine oxidase inhibitor (MAOI) therapy per protocol.

Health Teaching

  • Explain that behavior-based cessation support improves quit success versus medication alone.
  • Teach toxicity warning signs and when to stop therapy and call the provider.
  • Reinforce daily adherence and site rotation to reduce skin reactions.
  • Instruct patients to seek help if cravings remain uncontrolled rather than layering non-prescribed nicotine products.

Self-Check

  1. Why must patients stop smoking completely while on nicotine patch therapy?
  2. What symptoms suggest nicotine overdose and require immediate escalation?
  3. How should a used nicotine patch be handled and disposed safely?
