Abnormally low blood pressure after ingestion of deet may occur. Acute exposure - neurologic: Dizziness occurred in a human exposure to 10 g of dbp. Polyneuritis was reported in one soviet study. There have been several animal and laboratory tests done on the possible teratogenic effect of DBP. The results have been mixed. Studies done on Salmonella cultures have shown mildly positive mutagenic responses. DBP appears to affect females more than males, at least in the rodent studies performed.
Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause central nervous system depression.
Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Causes respiratory tract irritation.
May cause skin irritation.
Produces irritation, characterized by a burning sensation, redness, tearing, inflammation, and possible corneal injury.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
