Nicorette Berrymint (Nicotine)

Nicotine delivered via Nicorette Berrymint is used in nicotine replacement therapy to support smoking cessation.

• Smoking cessation: assists adult smokers in quitting by reducing cravings and withdrawal symptoms.
• Nicotine dependence: provides a controlled nicotine dose to ease transition away from cigarettes.
• Relapse prevention: helps maintain abstinence by managing occasional urges during the quitting process.

• Nicotine acts as a partial agonist at neuronal nicotinic acetylcholine receptors (nAChRs) in the central nervous system. By binding to these receptors, it stimulates modest dopamine release, which mitigates the deficit caused by tobacco abstinence, while simultaneously occupying the receptors to block the reinforcing effects of smoked nicotine, thereby reducing cravings and withdrawal. The controlled oral absorption provides steady plasma nicotine levels, avoiding the rapid spikes associated with smoking.

Nicotine replacement therapy can be associated with a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Mouth irritation: soreness or tingling in the oral cavity.
• Nausea: mild upset stomach or feeling of queasiness.
• Headache: transient headache episodes.
• Dizziness: light‑headed sensation, especially when standing quickly.
• Increased salivation: excess saliva production.
• Throat discomfort: irritation or dryness.
• Taste disturbance: unusual taste perception.
• Indigestion: mild heartburn.

Serious or Rare Side Effects

• Cardiovascular events: chest pain, palpitations, or hypertension.
• Severe allergic reaction: rash, itching, swelling, or difficulty breathing.
• Persistent vomiting: prolonged vomiting leading to dehydration.
• Mood changes: anxiety, irritability, or depression worsening.
• Hypotension: unusually low blood pressure causing faintness.
• Respiratory distress: severe shortness of breath or bronchospasm.

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

• Assess suitability: confirm the individual is an adult smoker seeking cessation.
• Review medical history: consider cardiovascular disease, diabetes, or gastrointestinal disorders.
• Avoid concurrent nicotine products: do not use cigarettes, e‑cigarettes, or other NRT simultaneously.
• Monitor for adverse reactions: discontinue if serious side effects occur and seek medical advice.
• Pregnancy and lactation: consult a healthcare professional before use.
• Store at ambient temperature: keep below 25 °C, in the original packaging, protected from moisture and direct sunlight.

Nicotine may interact with other medicines, altering their effects or increasing risk of adverse events.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): increased risk of hypertensive crisis.
• Certain antidepressants (e.g., tricyclics): heightened cardiovascular side effects.

Moderate Interactions (Monitor Closely)

• Caffeine: nicotine can enhance stimulant effects, leading to jitteriness.
• Anticoagulants (warfarin): nicotine may affect metabolism, requiring INR monitoring.
• Antipsychotics (e.g., clozapine): nicotine can induce hepatic enzymes, reducing drug levels.
• Beta‑blockers: nicotine may blunt therapeutic response, requiring dose adjustment.
