No data are available in humans regarding overdose by accidental or deliberate ingestion. Accidental ingestion of the entire contents of a bottle of olopatadine ophthalmic solution would deliver a maximum systematic exposure of 5mg olopatadine. This exposure would result in a final dose of 0.5mg/kg in a 10kg infant, assuming 100% absorption.
In the case of overdose, appropriate monitoring and management of the patients should be implemented.
