If the symptoms of nicotine poisoning are relatively mild, such as dizziness, headache, nausea, vomiting or poor mental concentration and mental state, the treatment is usually symptomatic and can be based on rest, oxygen intake and drinking more water to produce urine and speed up the metabolism of nicotine in the body. Generally the half-life of nicotine metabolism in the blood is about two hours, after the metabolism is completed, the symptoms are generally relieved. If the symptoms are more serious, in addition to nausea, vomiting, dizziness, headache and other symptoms, there will also be a poor state of consciousness, or even coma, convulsions, central respiratory depression, etc. In the case of stabilization of vital signs, we must urgently apply for hemodialysis detoxification treatment.
