Note to physician – According to HSDB, gastric lavage should be considered if potentially life-
threatening levels of Metaldehyde have been ingested, if the procedure can be performed
within one hour of ingestion. This procedure should be performed cautiously due to the
possibility of convulsions, which are most likely to occur one hour or later after ingestion.
Activated charcoal slurry (30 g charcoal per 240 ml water) may be administered, with the usual
dose of 25 to 100 g in adults and adolescents, 25 to 50 g in 1 to 12 year old children, and 1 g/kg
in infants under 1 year old. To control seizures, diazepam may be administered (5 to 10 mg
repeated every 10 to 15 minutes as needed for adults and 0.2 to 0.5 mg/kg repeated every 5
minutes as needed for children), or lorazepam may be administered at 4 to 8 mg for adults and
0.05 to 0.1 mg/kg for children. If seizures persist or recur after 30 mg of diazepam has been
administered to adults, or 10 mg has been administered to children age 5 or above, consider the
use of phenobarbitol and/or phenytoin or fosphenytoin. (the administration of diazepam or
clonidine 20 minutes after ingestion of 1000 mg/kg of Metaldehyde by mice delayed the onset of
symptoms and reduced mortality.) For acute inhalation overexposure, the patient should be
monitored as respiratory failure may occur 24 to 48 hours after exposure.
