If you take traditional Chinese medicine or proprietary Chinese medicine, and the ingredients in it are not toxic, usually the adverse reactions will gradually disappear after a period of rest after stopping the medicine. If you take western medicine, it must depend on the severity of its symptoms. If the symptoms are mild, there will generally be digestive discomfort, stomach discomfort such as nausea or abdominal pain, you must wait for a period of observation after stopping the medication. If the symptoms slowly get better, it is fine. But if there are more serious allergic symptoms, with a generalized rash, hives, and in severe cases, cold sweat and pale face, or in more serious cases, shock and coma, this situation should be immediately taken to the hospital for regular treatment.
