Massive ingestion, particularly by children, may cause depression or stimulation of CNS, even convulsions.
Urgent instructions to follow: Induce vomiting after drinking a glass of water. If vomit can not be induced, proceed to gastric lavage with saline serum. Saline cathartics are also useful (magnesia milk, eg.). In case hypotension appears, some vasopressor must be used. Anyhow, hospital assistance is recommended.
In case of overdosage or accidental intake, consult the Toxicology Information Service.
