Nicorette (Nicotine Resinate 20%)

Nicorette is a nicotine replacement therapy used to address nicotine dependence and support smoking cessation.

• Cigarette smoking cessation: helps adult smokers quit cigarettes by reducing nicotine withdrawal symptoms.
• Chewing tobacco cessation: assists users of smokeless tobacco in overcoming dependence through controlled nicotine delivery.
• Pipe and cigar cessation: provides a substitute nicotine source to ease quitting of pipe or cigar use.

• Nicotine resinate releases nicotine across the oral mucosa, allowing rapid absorption into the bloodstream. The absorbed nicotine binds to nicotinic acetylcholine receptors in the central nervous system, partially stimulating these receptors and mimicking the effect of tobacco‑derived nicotine. This controlled stimulation reduces the intensity of withdrawal and craving, facilitating a gradual reduction in the smoker’s dependence on nicotine.

Nicorette may cause a range of oral and systemic reactions, which are generally mild but can be serious in rare cases.

Common Side Effects

• Mouth irritation: mild soreness or tingling in the oral cavity.
• Nausea: transient feeling of queasiness.
• Headache: mild to moderate headache episodes.
• Hiccups: occasional involuntary diaphragmatic contractions.
• Increased salivation: excess saliva production.
• Taste disturbance: altered taste perception.

Serious or Rare Side Effects

• Severe allergic reaction: rash, swelling, or anaphylaxis requiring immediate medical attention.
• Chest pain: unexpected thoracic discomfort that may indicate cardiovascular stress.
• Irregular heartbeat: palpitations or arrhythmia.
• Persistent dizziness: prolonged vertigo affecting daily activities.
• Severe nausea/vomiting: leading to dehydration.
• Oral ulceration: painful sores that do not resolve.

When using Nicorette, several precautions should be observed to ensure safe and effective use.

• Assess nicotine dependence: evaluate the level of addiction before initiating therapy.
• Avoid use in children and adolescents: not recommended for individuals under 18 years.
• Monitor cardiovascular status: patients with heart disease should use under medical supervision.
• Do not combine with other nicotine products: avoid simultaneous use of cigarettes, e‑cigarettes, or other NRTs.
• Store at ambient temperature: keep below 25°C, in the original packaging, protected from moisture.

Nicotine can interact with other medicines, altering their effects or increasing adverse reactions.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): concurrent use may increase hypertensive risk.
• Beta‑blockers: nicotine may reduce their antihypertensive efficacy.
• Insulin or oral hypoglycemics: nicotine can affect glucose control, requiring dose adjustment.

Moderate Interactions (Monitor Closely)

• CYP1A2 substrates (e.g., theophylline, clozapine): nicotine induces metabolism, potentially lowering drug levels.
• Antidepressants (SSRIs, SNRIs): monitor for increased side effects such as insomnia or agitation.
• Anticoagulants (warfarin): nicotine may affect platelet function, requiring INR monitoring.
