Questran (cholestyramine) for Oral Suspension is used to lower high levels of cholesterol in the blood, especially low-density lipoprotein (LDL) ("bad" cholesterol). Questran powder is also used to treat itching caused by a blockage in the bile ducts of the gallbladder. It is a cholesterol-lowering agent. The brand name Questran is discontinued in the U.S. Generic forms may still be available. Common side effects include constipation, stomach/abdominal pain, gas, nausea, and vomiting.

The recommended starting adult dose for all cholestyramine powdered products is one packet or one level scoopful once or twice a day. The recommended maintenance dose is 2 to 4 packets or scoopfuls daily (8-16 grams anhydrous cholestyramine resin) divided into two doses. Cholestyramine may interact with blood thinners, digoxin, propranolol, diuretics (water pills), thyroid hormones, birth control pills or hormone replacement, seizure medicines, or antibiotics. Tell your doctor all medications you use. During pregnancy, cholestyramine should be used only when prescribed. It may affect the absorption of certain nutrients.

Questran FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

The most common adverse reaction is constipation. When used as a cholesterol-lowering agent predisposing factors for most complaints of constipation are high dose and increased age (more than 60 years old). Most instances of constipation are mild, transient, and controlled with conventional therapy. Some patients require a temporary decrease in dosage or discontinuation of therapy.

Less Frequent Adverse Reactions: Abdominal discomfort and/or pain, flatulence, nausea, vomiting, diarrhea, eructation, anorexia, and steatorrhea, bleeding tendencies due to hypoprothrombinemia (Vitamin K deficiency) as well as Vitamin A (one case of night blindness reported) and D deficiencies, hyperchloremic acidosis in children, osteoporosis, rash and irritation of the skin, tongue and perianal area. Rare reports of intestinal obstruction, including two deaths, have been reported in pediatric patients.

Occasional calcified material has been observed in the biliary tree, including calcification of the gallbladder, in patients to whom QUESTRAN (cholestyramine) has been given. However, this may be a manifestation of the liver disease and not drug related.

One patient experienced biliary colic on each of three occasions on which he took QUES-TRAN. One patient diagnosed as acute abdominal symptom complex was found to have a “pasty mass”in the transverse colon on x-ray.

Other events (not necessarily drug related) reported in patients taking QUESTRAN (cholestyramine) include: Gastrointestinal-GI-rectal bleeding, black stools, hemorrhoidal bleeding, bleeding from known duodenal ulcer, dysphagia, hiccups, ulcer attack, sour taste, pancreatitis, rectal pain, diverticulitis.
