[Case] Mr. Li, 40, was diagnosed with schizophrenia six months ago and was given antipsychotic medication by his doctor. Two months ago, the patient’s family stopped Mr. Li’s antipsychotic medication because they were afraid that the medication would have side effects, especially because they heard that antipsychotic medication would cause the formation of blood clots and make him prone to stroke. Now Mr. Li’s abnormal psychiatric symptoms have gradually worsened and violent behavior has appeared. Through this case, experts reminded that schizophrenia is a disease that is very harmful to society, families and the patients themselves, and early diagnosis and early treatment are very important factors to improve the efficacy and complete recovery. Therefore, timely treatment should be given after a diagnosis of schizophrenia is confirmed. Otherwise, the effectiveness of the treatment will be affected and the disease will be prolonged, which will seriously affect the social function of the patient. Experts also point out that any drug has different degrees of side effects, and antipsychotics are no exception. Antipsychotics include both typical and atypical drugs. Long-term use of both can cause varying degrees of weight gain, abnormal blood glucose and lipid metabolism, and can be easily complicated by diabetes, hyperlipidemia, hypertension, and atherosclerosis, which are all risk factors for blood clots. Reduce the risk of thrombosis 1. Use the lowest effective drug dose. Because any drug side effects are related to the drug dose, the higher the drug dose, the greater the side effects, weight gain, and the more significant the degree of abnormalities in glucose metabolism and lipid metabolism. For doctors, the dose of drugs must be controlled to the lowest effective dose, thus reducing risk factors. 2.Regular weighing, blood pressure measurement, blood glucose and lipid testing, any abnormal findings can be promptly treated symptomatically. 3, develop good lifestyle habits. Quit smoking, moderate exercise, small amount of alcohol, balanced diet and weight control can keep us away from the risk factors that cause blood clots and avoid the formation of blood clots. 4.Keep a good state of mind. Excessive anger, joy, thought, grief and fear, especially rage, are the most common triggers of thrombosis.
