We do not publish dosing. How much of this medicine to take, how often, and for how long depends on your age, weight, kidney and liver function, other conditions and other medicines.

What it is used to treat

INDICATIONS AND USAGE Since no drug is innocuous, strict attention should be paid to the indications and contraindications, particularly when selecting drugs for chronic long-term use. COLESTID Granules and FLAVORED COLESTID Granules are indicated as adjunctive therapy to diet for the reduction of elevated serum total and low-density lipoprotein (LDL) cholesterol in patients with primary hypercholesterolemia (elevated low density lipoproteins [LDL] cholesterol) who do not respond adequately to diet. Generally, COLESTID and FLAVORED COLESTID have no clinically significant effect on serum triglycerides, but with its use triglyceride levels may be raised in some patients. Therapy with lipid-altering agents should be a component of multiple risk factor intervention in those individuals at significantly increased risk for atherosclerotic vascular disease due to hypercholesterolemia. Treatment should begin and continue with dietary therapy (see NCEP guidelines ). A minimum of six months of intensive dietary therapy and counseling should be carried out prior to initiation of drug therapy. Shorter periods may be considered in patients with severe elevations of LDL-C or with definite CHD. According to the NCEP guidelines, the goal of treatment is to lower LDL-C, and LDL-C is to be used to initiate and assess treatment response. Only if LDL-C levels are not available, should the Total-C be used to monitor therapy. The NCEP treatment guidelines are shown below. LDL-Cholesterol mg/dL (mmol/L) Definite Atherosclerotic Disease Coronary heart disease or peripheral vascular disease (including symptomatic carotid artery disease). Two or More Other Risk Factors Other risk factors for coronary heart disease (CHD) include: age (males: ≥45 years; females: ≥55 years or premature menopause without estrogen replacement therapy); family history of premature CHD; current cigarette smoking; hypertension; confirmed HDL-C <35 mg/dL (0.91 mmol/L); and diabetes mellitus. Subtract one risk factor if HDL-C is ≥60 mg/dL (1.6 mmol/L). Initiation Level Goal No No ≥190 (≥4.9) <160 (<4.1) No Yes ≥160 (≥4.1) <130 (<3.4) Yes Yes or No ≥130 (≥3.4) ≤100 (≤2.6)

About this medicine

DESCRIPTION COLESTID Granules and FLAVORED COLESTID Granules contain colestipol hydrochloride, which is a lipid lowering agent for oral use. Colestipol hydrochloride is an insoluble, high molecular weight basic anion-exchange copolymer of diethylenetriamine and 1-chloro-2, 3-epoxypropane, with approximately 1 out of 5 amine nitrogens protonated (chloride form). It is a light yellow water-insoluble resin which is hygroscopic and swells when suspended in water or aqueous fluids. COLESTID is tasteless and odorless. Inactive ingredient: silicon dioxide. One dose (1 packet or 1 level teaspoon) of COLESTID contains 5 grams of colestipol hydrochloride. FLAVORED COLESTID is orange flavored and light orange in color. One dose (1 packet or 1 level scoopful) of FLAVORED COLESTID is approximately 7.5 grams powder which contains 5 grams of colestipol hydrochloride. This product also contains the following inactive ingredients: aspartame, beta carotene, citric acid, flavor (natural and artificial), glycerine, maltol, mannitol, and methylcellulose.

Who should not take it

CONTRAINDICATIONS COLESTID Granules and FLAVORED COLESTID Granules are contraindicated in those individuals who have shown hypersensitivity to any of its components.

Warnings

WARNINGS TO AVOID ACCIDENTAL INHALATION OR ESOPHAGEAL DISTRESS, COLESTID GRANULES AND FLAVORED COLESTID GRANULES SHOULD NOT BE TAKEN IN ITS DRY FORM. ALWAYS MIX COLESTID AND FLAVORED COLESTID WITH WATER OR OTHER FLUIDS BEFORE INGESTING. PHENYLKETONURICS: FLAVORED COLESTID CONTAINS 18.2 MG PHENYLALANINE PER 7.5-GRAM DOSE.

Reported side effects

ADVERSE REACTIONS Gastrointestinal The most common adverse reactions are confined to the gastrointestinal tract. To achieve minimal GI disturbance with an optimal LDL-cholesterol lowering effect, a gradual increase of dosage starting with one dose/day is recommended. Constipation is the major single complaint and at times is severe. Most instances of constipation are mild, transient, and controlled with standard treatment. Increased fluid intake and inclusion of additional dietary fiber should be the first step; a stool softener may be added if needed. Some patients require decreased dosage or discontinuation of therapy. Hemorrhoids may be aggravated. Other, less frequent gastrointestinal complaints consist of abdominal discomfort (abdominal pain and cramping), intestinal gas, (bloating and flatulence), indigestion and heartburn, diarrhea and loose stools, and nausea and vomiting. Bleeding hemorrhoids and blood in the stool have been infrequently reported. Peptic ulceration, cholecystitis, and cholelithiasis have been rarely reported in patients receiving colestipol hydrochloride granules, and are not necessarily drug related. Transient and modest elevations of aspartate aminotransferase (AST, SGOT), alanine aminotransferase (ALT, SGPT) and alkaline phosphatase were observed on one or more occasions in various patients treated with colestipol hydrochloride. The following non-gastrointestinal adverse reactions have been reported with generally equal frequency in patients receiving COLESTID Granules, FLAVORED COLESTID Granules, or placebo in clinical studies: Cardiovascular Chest pain, angina, and tachycardia have been infrequently reported. Hypersensitivity Rash has been infrequently reported. Urticaria and dermatitis have been rarely noted in patients receiving colestipol hydrochloride granules. Musculoskeletal Musculoskeletal pain, aches and pains in the extremities, joint pains, arthritis, and backache have been reported. Neurologic Headache, migraine headache and sinus headache have been reported. Other infrequently reported complaints include dizziness, light-headedness, and insomnia. […]

Interactions with other medicines

Drug Interactions Since colestipol hydrochloride is an anion exchange resin, it may have a strong affinity for anions other than the bile acids. In vitro studies have indicated that colestipol hydrochloride binds a number of drugs. Therefore, COLESTID and FLAVORED COLESTID resin may delay or reduce the absorption of concomitant oral medication. The interval between the administration of COLESTID and FLAVORED COLESTID and any other medication should be as long as possible. Patients should take other drugs at least one hour before or four hours after COLESTID and FLAVORED COLESTID to avoid impeding their absorption. Repeated doses of colestipol hydrochloride given prior to a single dose of propranolol in human trials have been reported to decrease propranolol absorption. However, in a follow-up study in normal subjects, single dose administration of colestipol hydrochloride and propranolol and twice-a-day administration for 5 days of both agents did not effect the extent of propranolol absorption, but had a small yet statistically significant effect on its rate of absorption; the time to reach maximum concentration was delayed 30 minutes. Effects on the absorption of other beta-blockers have not been determined. Therefore, patients on propranolol should be observed when COLESTID or FLAVORED COLESTID is either added or deleted from a therapeutic regimen. Studies in humans show that the absorption of chlorothiazide as reflected in urinary excretion is markedly decreased even when administered one hour before colestipol hydrochloride. The absorption of tetracycline, furosemide, penicillin G, hydrochlorothiazide, and gemfibrozil was significantly decreased when given simultaneously with colestipol hydrochloride; these drugs were not tested to determine the effect of administration one hour before colestipol hydrochloride. No depressant effect on blood levels in humans was noted when colestipol hydrochloride was administered with any of the following drugs: aspirin, clindamycin, clofibrate, methyldopa, nicotinic acid (niacin), tolbutamide, phenytoin or warfarin. […]

If too much is taken

OVERDOSAGE Overdosage of COLESTID Granules or FLAVORED COLESTID Granules has not been reported. Should overdosage occur, however, the chief potential harm would be obstruction of the gastrointestinal tract. The location of such potential obstruction, the degree of obstruction and the presence or absence of normal gut motility would determine treatment.
