4.9   Overdose

In overdose, symptoms corresponding to heavy smoking may be seen.
Even small quantities of nicotine are dangerous in children and may result in severe symptoms of poisoning which may prove fatal. If poisoning is suspected in a child, a doctor must be consulted immediately.

Overdose with Nicotinell lozenges may only occur if many pieces are sucked simultaneously. Nicotine toxicity after ingestion will most likely be minimised as a result of early nausea and vomiting that occur following excessive nicotine exposure.

Signs and symptoms of an overdose from nicotine lozenges would be expected to be the same as those of acute nicotine poisoning, including: weakness, perspiration, pallor, heperhidrosis, salivation, throat burn, nausea, vomiting, diarrhoea, abdominal pain, hearing and visual disturbances (sensory disturbance), headache, tachycardia and cardiac arrhythmia, dyspnoea, dizziness, tremor, confusional state and asthenia. Prostration, hypotension, circulatory collapse, coma, respiratory failure and terminal convulsions may ensue with large overdose

Treatment of overdose:
In the event of an overdose (e.g., too many lozenges ingested) medical attention should be sought immediately. All nicotine intake should cease immediately, and the patient be treated symptomatically, and vital signs monitored.
Further management should be as clinically indicated or as recommended by the national poisons centre, where available.
