      Calcium

      Replenish Depleted Nutrients

      Bile acid sequestrants, including colestipol, may prevent absorption of folic acid and the fat-soluble vitamins A, D, E, K. 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.

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

      Milk Thistle

      Reduce Side Effects

      Milk thistle’s (Silybum marianum) major flavonoids, known collectively as silymarin, have shown synergistic actions with the chemotherapy drugs cisplatin and doxorubicin (Adriamycin®) in test tubes. Silymarin also offsets the kidney toxicity of cisplatin in animals. Silymarin has not yet been studied in humans treated with cisplatin. There is some evidence that silymarin may not interfere with some chemotherapy in humans with cancer.
