After the occurrence of adverse drug reactions should immediately stop the drug, observe the vital signs, active treatment, make a good record, and promptly report to the hospital. Before using drugs, we should first understand the indications and contraindications of drugs, and master the principle of drug use. When an adverse drug reaction occurs, the first step is to stop the drug immediately. Measure and record vital signs, including respiration, pulse, temperature and blood pressure. If the patient’s symptoms are not serious, give appropriate treatment; if the patient’s symptoms are serious, timely rescue treatment, and actively take anti-shock treatment. Record the name, batch number, model, production date, expiration date and patient’s symptoms of the drug that had an adverse reaction, and report it to the Clinical Drug Monitoring Center. At the same time, make records and report to the hospital.
