Reducing high cholesterol levels. It may be used alone or with other medicines, in addition to diet and exercise. It is also used along with other medicines to control blood sugar in patients with type 2 diabetes.
Welchol is a bile acid sequestrant. It works by increasing the removal of bile acids from the body. As the body loses bile acids, it replaces them by converting cholesterol from the blood to bile acids. This causes the blood level of cholesterol to decrease.
