Diarrhea: Assess frequency, amount, and consistency of stools.

Lab Test Considerations:

Serum cholesterol and triglyceride levels should be evaluated before initiating, frequently during first few mo and periodically throughout therapy. Discontinue medication if paradoxical increase in cholesterol level occurs.
- May cause an increase in AST, ALT, phosphorus, chloride, and alkaline phosphatase and a decrease in serum calcium, sodium, and potassium levels.
- May also cause prolonged prothrombin times.

Parenteral or water-miscible forms of fat-soluble vitamins (A, D, and K) and folic acid may be ordered for patients on chronic therapy.
PO: Administer before meals.
- Scoops for powdered preparations may not be exchangeable between products.
- Administer other medications 1 hr before or 4–6 hr after the administration of this medication.

Instruct patient to take medication exactly as directed; do not skip doses or double up on missed doses.
Instruct patient to take medication before meals. Mix cholestyramine with 4–6 oz water, milk, fruit juice, or other noncarbonated beverages. Shake vigorously. Slowly stir in a large glass. Rinse glass with small amount of additional beverage to ensure all medication is taken. May also mix with highly fluid soups, cereals, or pulpy fruits (applesauce, crushed pineapple). Allow powder to sit on fluid and hydrate for 1–2 min before mixing. Do not take dry. Variations in the color of cholestyramine do not alter stability.
Advise patient that this medication should be used in conjunction with dietary restrictions (fat, cholesterol, carbohydrates, alcohol), exercise, and cessation of smoking.
Explain that constipation may occur. Increase in fluids and bulk in diet, exercise, stool softeners, and laxatives may be required to minimize the constipating effects. Instruct patient to notify health care professional if constipation, nausea, flatulence, and heartburn persist or if stools become frothy and foul smelling.
Advise patient to notify health care professional if unusual bleeding or bruising; petechiae; or black, tarry stools occur. Treatment with vitamin K may be necessary.
Rep: Advise females of reproductive potential to notify health care professional if pregnancy is planned or suspected or if breastfeeding. May interfere with absorption of fat-soluble vitamins in pregnant women and in infants of women breastfeeding.

Decrease in serum low-density lipoprotein cholesterol levels. Therapy is usually discontinued if the clinical response remains poor after 3 mo of therapy.
Decrease in severity of pruritus. Relief usually occurs 1–3 wk after therapy is initiated.
Decrease in frequency and severity of diarrhea.
