You should not stop taking ezetimibe suddenly. Ezetimibe is mainly used for the treatment of primary hypercholesterolemia and pure familial hypercholesterolemia. Ezetimibe reduces the level of cholesterol in the blood by inhibiting the absorption of cholesterol in the small intestine. It also attaches itself to the brush border of the villous epithelium of the small intestine, thus inhibiting the absorption of cholesterol. Long-term treatment with this medication is usually required. If the drug is stopped suddenly, it may lead to an increase in blood lipids, thus failing to achieve the desired lipid-lowering effect. It is necessary to maintain a low-quality diet while taking the medication, either on an empty stomach or with food. Ezetimibe may cause abdominal pain, diarrhea, cough, hot flashes, fatigue and other unpleasant symptoms after taking it. People who are allergic to the components of this drug, active liver disease need to be prohibited from taking it. Caution should also be exercised for pregnant and breastfeeding women, as well as for those who use the anticoagulant drug cyclosporine. If you need to take Ezetimibe due to a medical condition, it is recommended to consult a doctor, who will decide on the dosage of the drug and learn the precautions after a comprehensive assessment of the condition.
