Disulfiram is a drug that inhibits the enzyme acetaldehyde dehydrogenase in the liver, resulting in a toxic reaction from the conversion of ethanol to acetaldehyde. Disulfiram is commonly seen as a life-threatening manifestation of dizziness, nausea, and vomiting caused by alcohol consumption after taking oral cephalosporins and other drugs. Self-treatment is to stop drinking immediately, induce vomiting, lie flat on a hard bed, and keep warm. It is recommended to go to the hospital for oxygen and monitoring to maintain vital signs. In addition, in the event of a life-threatening situation in the hospital, doctors can make every effort to resuscitate the patient and ensure the safety of life.
