Nicorette Microtab (Nicotine Betadex)

Nicorette Microtab, a nicotine replacement therapy, is used to address nicotine dependence and related withdrawal.

• Smoking cessation: assists adult smokers in quitting by providing controlled nicotine delivery.
• Nicotine withdrawal management: reduces cravings and withdrawal symptoms during the quitting process.
• Relapse prevention: supports maintaining abstinence after initial cessation.

• Nicotine Betadex acts as an agonist at neuronal nicotinic acetylcholine receptors, primarily the α4β2 subtype, mimicking the pharmacologic effects of tobacco‑derived nicotine. By stimulating these receptors, it alleviates withdrawal symptoms and cravings while allowing gradual reduction of nicotine exposure. The sublingual route provides rapid absorption through the oral mucosa, achieving steady plasma concentrations that help stabilize the smoker’s neurochemical balance during cessation attempts.

Nicorette Microtab may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Mouth irritation: mild soreness or tingling under the tongue.
• Nausea: feeling of queasiness after administration.
• Headache: mild to moderate head discomfort.
• Dizziness: transient light‑headed sensation.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Chest pain: unexpected thoracic discomfort that may indicate cardiac involvement.
• Severe hypotension: marked drop in blood pressure leading to faintness.

Before using Nicorette Microtab, consider the following precautions to ensure safe and effective therapy.

• Assess nicotine dependence: evaluate smoking history and level of dependence prior to initiation.
• Medical supervision: use under guidance of a healthcare professional, especially for cardiovascular disease.
• Avoid concurrent nicotine products: do not combine with other nicotine replacement therapies or tobacco to prevent overdose.
• Not for non‑smokers: the product is intended only for individuals who are regular tobacco users seeking cessation.
• Keep out of reach of children: store securely to prevent accidental ingestion.
• Store at ambient temperature: keep in the original packaging, protect from moisture and excessive heat.

Nicotine can interact with other medicines, requiring attention to potential additive or metabolic effects.

Major Interactions (Avoid)

• Concurrent use of multiple nicotine replacement products: risk of nicotine toxicity and related symptoms.
• Use with illicit nicotine sources (e.g., e‑cigarettes): may lead to excessive nicotine exposure.

Moderate Interactions (Monitor Closely)

• CYP1A2 substrate drugs (e.g., theophylline, clozapine): nicotine may increase their metabolism, reducing efficacy.
• Beta‑adrenergic antagonists: nicotine‑induced tachycardia may be blunted, requiring monitoring.
• MAO‑inhibitor antidepressants: combined use may increase risk of hypertension; observe blood pressure.
