Toxic reactions are usually caused by overdose or prolonged use of drugs, resulting in adverse reactions in tissues and organs in the body, or in some cases, by exposure to inappropriate foods and substances. There are many symptoms of toxic reactions, such as rash, fever, cough, pain and other symptoms, and in severe cases, liver and kidney failure, which may even endanger life. When there is a significant discomfort in the body, it is necessary to go to the hospital as soon as possible to improve the relevant examination and give relevant treatment. During the treatment period, patients should pay attention to their living habits, such as not to drink alcoholic beverages, not to eat too spicy food, and not to eat pickled food, which may further aggravate the disease, and to increase the intake of water, fresh fruits and green vegetables, as well as to increase rest.
