If hypercholesterolemia is not combined with diabetes mellitus, hypertension, coronary heart disease, etc., the drug can be discontinued as appropriate when the blood lipids return to normal, otherwise it needs to be taken for a long time. If the patient’s condition is without cardiovascular risk factors such as coronary heart disease, diabetes mellitus, hypertension and other cardiovascular risk factors, and only simple dyslipidemia, then when the patient’s blood lipids return to normal after using the medication and is able to maintain the normal level of blood lipids by adjusting the lifestyle, he/she can consider discontinuing the use of the medication under the guidance of the doctor. However, if the patient’s dyslipidemia is serious and accompanied by cardiovascular risk factors or comorbidities, the patient should use lipid-lowering drugs for life to reduce the risk of myocardial infarction and other complications. At the same time, they should pay attention to develop healthy dietary habits, such as choosing vegetable oils as much as possible and minimizing the consumption of animal fats and saturated fatty acids. The use of specific drugs should be under the guidance of a doctor.
