Symptoms: The principal toxic effect is on the bone marrow and haematological toxicity is likely to be more profound with chronic overdosage than with a single ingestion of LANVIS.
Treatment: As there is no known antidote the blood picture should be closely monitored and general supportive measures, together with appropriate blood transfusion, instituted if necessary.
Further management should be as clinically indicated or as recommended by the national poisons centre, where available.
