Wash skin with soap and water. Eye contamination should be removed by prolonged flushing of the eye with copious amounts of clean water or saline. If irritation persists, specialized medical treatment should be obtained. If a substantial amount of DEET has been ingested within an hour of treatment, gastrointestinal decontamination should be considered. Induced emesis is usually considered contraindicated in these poisonings due to the rapid onset of seizures.
Treatment is primarily supportive, with control of seizures by anticonvulsants.
Persons surviving poisoning by ingestion of DEET have usually recovered within 36 hours or less.
