You should not take this medication if you are allergic to colestipol, or if you have a blockage in your intestines.
Before taking colestipol, tell your doctor if have trouble swallowing, constipation or hemorrhoids, a stomach or intestinal disorder, liver disease, a thyroid disorder, a bleeding disorder, a history of major stomach or bowel surgery, or if you have a vitamin A, D, E, or K deficiency.

Colestipol is only part of a complete program of treatment that also includes diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.
Do not take other medications at the same time you take colestipol. Taking colestipol can make it harder for your body to absorb certain drugs, making them less effective. Take your other medications at least 1 hour before or 4 hours after you take colestipol.
Avoid constipation by drinking 8 to 12 full glasses (8 ounces each) every day while taking this medication. Ask your doctor before using a laxative or stool softener.
Call your doctor at once if you have severe constipation or stomach pain.
To be sure colestipol is helping your condition, your blood will need to be tested often. This will help your doctor determine how long to treat you with colestipol. Do not miss any scheduled appointments.
