Niquitin (Nicotine)

Niquitin is a nicotine replacement therapy used to support smoking cessation by providing a steady transdermal nicotine supply.

• Smoking cessation: assists adults who want to quit tobacco smoking by reducing cravings and withdrawal symptoms.
• Nicotine dependence: helps patients gradually lower nicotine intake while transitioning away from cigarettes.
• Tobacco use disorder: offers a non‑combustible nicotine source to facilitate a quit attempt under medical guidance.

• Nicotine in the patch penetrates the skin and binds to nicotinic acetylcholine receptors in the central nervous system. This stimulation mimics the pharmacologic effects of inhaled nicotine, decreasing the intensity of withdrawal symptoms and cravings, thereby supporting a gradual reduction in tobacco use while maintaining receptor occupancy.

Niquitin may cause a range of adverse reactions, most of which are related to the transdermal delivery system.

Common Side Effects

• Skin irritation at the application site: redness, itching, or mild rash.
• Sleep disturbance: difficulty falling asleep or staying asleep.
• Vivid dreams or abnormal sleep patterns.
• Nausea or mild gastrointestinal upset.
• Headache.

Serious or Rare Side Effects

• Severe allergic reaction: swelling, hives, or difficulty breathing.
• Significant skin necrosis or ulceration.
• Cardiovascular events: chest pain, palpitations, or hypertension.
• Hypotension or dizziness.
• Seizures (rare, especially with high nicotine exposure).

Before using Niquitin, consider the following safety measures.

• Cardiovascular assessment: evaluate patients with heart disease or recent myocardial infarction.
• Pregnancy and lactation: avoid use unless benefits outweigh potential risks.
• Concomitant nicotine products: do not use other nicotine replacement therapies simultaneously.
• Skin integrity: apply to clean, dry, non‑irritated skin and rotate sites.
• Children safety: keep patches out of reach of children and pets.
• Store at room temperature: keep in original packaging, protect from moisture and direct heat.

Niquitin can interact with other medicines, influencing nicotine levels or cardiovascular response.

Major Interactions (Avoid)

• Concurrent nicotine replacement therapy: may lead to nicotine overdose.
• Bupropion or other seizure‑threshold‑lowering agents: increased risk of seizures.
• Cardiovascular stimulants (e.g., ephedrine): may exacerbate tachycardia or hypertension.

Moderate Interactions (Monitor Closely)

• CYP2A6 inhibitors (e.g., methoxsalen): may raise nicotine plasma concentrations.
• Hormonal contraceptives: nicotine may reduce contraceptive efficacy.
• Alcohol consumption: can increase nicotine metabolism, altering effectiveness.
• Certain antidepressants (e.g., SSRIs): may require monitoring for altered nicotine clearance.
