Eflornithine is usually an insecticide, and the poisoning is mainly contact poisoning, which is usually manifested by contact with the mucous membrane of the scalp or the skin. If it is accidentally taken orally, it must be sent to the hospital immediately to give gastric lavage and diarrhea treatment, so that the poison can be discharged from the body as soon and as much as possible. If the symptoms of poisoning are very serious, leading to coma, convulsions and shock, then under the condition of stabilizing the vital signs, application for blood purification should be given to detoxify the poison. If the symptoms are mild, such as dizziness, headache, nausea and vomiting, it is fine to give accelerated rehydration and then induce diarrhea and symptomatic treatment.
