Indications

Cholestyramine Resin (Olestar) is used alongside diet and exercise to bring down raised serum cholesterol in people with primary hypercholesterolemia, which means high low-density lipoproteins. Lowering the cholesterol this way may reduce the risk of atherosclerotic coronary artery disease and myocardial infarction. It may also help lower raised cholesterol in people who have combined hypercholesterolemia and hypertriglyceridemia. But it is not indicated where hypertriglyceridemia is the main concern. Cholestyramine Resin is also used for symptomatic control of bile acid-induced diarrhea due to short bowel syndrome. And it is used to relieve pruritus associated with partial biliary obstruction.

⚠️ Always consult a registered physician before taking any medicine.

Pregnancy & Breastfeeding

Pregnancy

Cholestyramine resin is not absorbed into the body, so it isn't expected to harm the baby when it is taken in the recommended doses during pregnancy. But there are no adequate and well controlled studies in pregnant women. The resin is also known to interfere with the absorption of fat soluble vitamins, and this may be harmful even when vitamins are given as supplements.

Nursing mothers

Be careful when giving cholestyramine resin to a nursing mother. The possible poor absorption of vitamins, described under pregnancy above, may affect a breastfed infant. In pregnancy or breastfeeding, the doctor must weigh the possible benefits of the treatment against the possible harm to the mother and the child.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Dosage Reference

⚠️ Reference ranges from official sources only. Consult your doctor for personalized dosing.

Adults: Start every course of Cholestyramine Resin Light Powder with one dose a day. This helps the patient get used to the powder and keeps stomach and bowel side effects down. Within a day or two, the dose is raised to the level needed for good control. Patients need to be motivated to carry on with the prescribed regimen even if they have gastrointestinal problems. Encouragement and supervision from the physician are essential for successful management. The recommended adult dose is 4 grams of cholestyramine resin, one to six times daily. Doses may be adjusted as the patient requires. A pediatric dosage schedule has not been established.
