Colestipol

Also indexed as: Colestid

Colestipol is a bile acid sequestrant (prevents absorption of bile acids in the digestive system). Bile acids may facilitate the absorption of cholesterol. Colestipol is one of many drugs used to lower cholesterol levels in people with high blood cholesterol.

Interactions with Dietary Supplements

Vitamins
Bile acid sequestrants, including colestipol, may prevent absorption of folic acid and the fat-soluble vitamins A, D, E, K.¹ ² People taking colestipol should consult with their doctor about vitamin malabsorption and supplementation. People should take other drugs and vitamin supplements one hour before or four to six hours after colestipol to improve absorption.³

Animal studies suggest calcium and zinc may be depleted by taking cholestyramine, another bile acid sequestrant. ⁴ Whether these same interactions would occur with colestipol is not known.

Carotenoids
Use of colestipol for six months has been shown to significantly lower blood levels of carotenoids including beta-carotene.⁵

Interactions with Foods and Other Compounds

Water
Bile acid sequestrants should be taken with plenty of water before meals.⁶
