No significant undesirable effects have been observed following single dose administration of up to 240 mg or up to 120 mg (3 times daily) for eight days.
There is a single case of overdose in a three-year-old child treated with a daily dose of levodropropizine 360 mg. The patient had abdominal and vomitus pains that were not severe and resolved without consequence. In the case of overdosage, the usual therapeutic measures (gastric lavage, charcoal, parenteral fluid administration, etc.) should be performed.
