Nicorette (Nicotine)

Nicorette is a nicotinic receptor agonist indicated for conditions related to tobacco use and nicotine dependence.

• Smoking cessation: helps adult smokers quit by alleviating cravings and withdrawal symptoms.
• Tobacco dependence: supports reduction of nicotine intake in individuals who use tobacco products.
• Nicotine dependence: assists in managing dependence during a structured quit‑attempt program.

• Nicotine binds to nicotinic acetylcholine receptors in the brain, partially stimulating them and thereby reducing the intensity of withdrawal symptoms and cravings that occur when tobacco use is stopped. This receptor activation provides a controlled dose of nicotine, helping to ease the transition away from smoking.

Nicorette may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Throat irritation: mild soreness or burning sensation in the throat.
• Mouth soreness: discomfort in the oral mucosa.
• Nausea: feeling of queasiness or upset stomach.
• Headache: mild to moderate head pain.
• Dizziness: sensation of light‑headedness.
• Hiccups: involuntary diaphragm contractions.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Chest pain: unexpected discomfort in the chest area.
• Irregular heartbeat: palpitations or abnormal heart rhythm.
• Severe mouth ulcer: large or persistent ulceration in the oral cavity.
• Hypertension: significant increase in blood pressure.
• Respiratory distress: difficulty breathing or wheezing.

Before using Nicorette, consider the following safety measures.

• Cardiovascular assessment: patients with recent heart attack or unstable angina should seek medical advice.
• Pregnancy safety: use is not recommended during pregnancy due to unknown fetal risk.
• Breastfeeding: avoid use while nursing unless advised by a healthcare professional.
• Concomitant nicotine products: do not use with other nicotine replacement therapies simultaneously.
• Duration of therapy: limit use to the period recommended by a healthcare provider to prevent dependence.
• Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Nicorette can interact with other medicines; monitor the following.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): may increase risk of hypertension.
• CYP2A6 inhibitors: can raise nicotine plasma levels, enhancing side effects.

Moderate Interactions (Monitor Closely)

• Antidepressants (SSRIs, SNRIs): may alter nicotine metabolism.
• Antihypertensive drugs: nicotine may reduce their effectiveness.
• Alcohol: concurrent use may increase cravings and side effects.
• Caffeine: nicotine can enhance stimulant effects, leading to jitteriness.
• Beta‑blockers: nicotine may interfere with heart rate control.
