📖 What it is MedlinePlus · NLM

Colesevelam is used to decrease the amount of cholesterol (a fat-like substance that can build up in blood vessels leading to heart attack or strokes or other medical conditions) control blood sugar levels in adults with type 2 diabetes (condition in which the body does not use insulin normally leading to high blood sugar) Colesevelam is in a class of medications called bile acid sequestrants. It works by binding bile acids in your intestines to form a product that is removed from the body.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🗺️ Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for 00713-0879-81, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.
📅 Q1 2025 – Q4 2025 · 4 quarters of data

💵 About the dollar figures: “reimbursed” is what Medicaid paid pharmacies before confidential manufacturer rebates, so the program’s real net cost is lower than these numbers.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Welchol — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Welchol. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

What does the discontinued status mean for this NDC?
The labeler reported a marketing end date (or the listing was delisted), so this specific package is no longer actively marketed. Remaining stock may still be dispensed for a time, and the NDC stays valid for historical records and claims — but data feeds (pricing, labeling) typically stop updating for it. Other package sizes or other manufacturers' versions of the same medication may still be marketed — see the equivalents section where available.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 0713-0879-81, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 00713-0879-81, written without dashes as 00713087981. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 00713-0879-81, the first segment (00713) is the labeler code FDA assigned to Cosette Pharmaceuticals, Inc.; the middle segment (0879) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (81) identifies this exact package size and type. Together they name one specific package of one specific product.
Who lists this product with the FDA?
Cosette Pharmaceuticals, Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.

Instruct patients to discontinue WELCHOL and seek prompt medical attention if the symptoms of acute pancreatitis occur ( 5.1 ). Gastrointestinal Obstruction: Cases of bowel obstruction have occurred. WELCHOL is not recommended in patients with gastroparesis, other gastrointestinal motility disorders, and in those who have had major gastrointestinal tract surgery and who may be at risk for bowel obstruction ( 5.2 ).

Vitamin K or Fat-Soluble Vitamin Deficiencies: WELCHOL may decrease absorption of fat-soluble vitamins. Patients with a susceptibility to deficiencies of vitamin K (e.g., patients on warfarin, patients with malabsorption syndromes) or other fat-soluble vitamins may be at increased risk. Patients on oral vitamin supplementation should take their vitamins at least 4 hours prior to WELCHOL ( 5.3 ).

Drug Interactions: Due to the potential for decreased absorption of other drugs that have not been tested for interaction, consider administering at least 4 hours prior to WELCHOL ( 5.4 , 7 , 12.3 ). Risks in Patients with Phenylketonuria (PKU): Phenylalanine can be harmful to patients with phenylketonuria. WELCHOL for oral suspension contains 27 mg phenylalanine per 3.75 gram packet ( 5.5 , 11 ).

5.1Hypertriglyceridemia and Pancreatitis WELCHOL, like other bile acid sequestrants, can increase serum TG concentrations. Hypertriglyceridemia can cause acute pancreatitis. WELCHOL had effects on serum TG (median increase 5% compared to placebo) in trials of patients with primary hyperlipidemia.

In trials in patients with type 2 diabetes, greater increases in TG levels occurred when WELCHOL was used as monotherapy (median increase 9.7% compared to placebo) and when WELCHOL was used in combination with pioglitazone (median increase 11% compared to placebo in combination with pioglitazone), sulfonylureas (median increase 18% compared to placebo in combination with sulfonylureas), and insulin (median increase 22% compared to placebo in combination with insulin) [see Adverse Reactions (6.1) ]. Obtain lipid parameters, including TG levels, before starting WELCHOL and periodically thereafter.

WELCHOL is contraindicated in patients with TG levels >500 mg/dL or patients with a history of hypertriglyceridemia-induced pancreatitis [see Contraindications (4) ] . Patients with TG levels greater than 300 mg/dL could have greater increases in serum TG levels with WELCHOL and may require additional TG monitoring. Instruct patients to discontinue WELCHOL and seek prompt medical attention if the symptoms of acute pancreatitis occur (e.g., severe abdominal pain with or without nausea and vomiting).

Discontinue WELCHOL if TG levels exceed 500 mg/dL [see Adverse Reactions (6.1) ] .

5.2Gastrointestinal Obstruction Postmarketing cases of bowel obstruction have occurred with WELCHOL [see Adverse Reactions (6.2) ] . Because of its constipating effects, WELCHOL is not recommended in patients with gastroparesis, other gastrointestinal motility disorders, and in those who have had major gastrointestinal tract surgery and who may be at risk for bowel obstruction. WELCHOL is contraindicated in patients with a history of bowel obstruction [see Contraindications (4) ] .

Instruct patients to promptly discontinue WELCHOL and seek medical attention if severe abdominal pain or severe constipation occurs. Because of the tablet size, WELCHOL tablets can cause dysphagia or esophageal obstruction. For patients with difficulty swallowing tablets, use WELCHOL for oral suspension.

5.3Vitamin K or Fat-Soluble Vitamin Deficiencies WELCHOL may decrease the absorption of fat-soluble vitamins A, D, E, and K. Patients with a susceptibility to deficiencies of vitamin K (e.g., patients on warfarin, patients with malabsorption syndromes) or other fat-soluble vitamins may be at increased risk when taking WELCH…

6.1Clinical Studies Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in clinical studies of another drug and may not reflect the rates observed in practice. Primary Hyperlipidemia In 7 double-blind, placebo-controlled clinical trials, 807 patients with primary hyperlipidemia (age range 18-86 years, 50% women, 90% Caucasians, 7% Blacks, 2% Hispanics, 1% Asians) and elevated LDL-C were treated with WELCHOL 1.5 g/day to 4.5 g/day from 4 to 24 weeks (total exposure 199 patient-years).

Table 1 Clinical Studies of WELCHOL for Primary Hyperlipidemia: Adverse Reactions Reported in ≥ 2% of Patients and More Commonly than in Placebo WELCHOL N=807 Placebo N=258 Constipation 11.0% 7.0% Dyspepsia 8.3% 3.5% Nausea 4.2% 3.9% Accidental injury 3.7% 2.7% Asthenia 3.6% 1.9% Pharyngitis 3.2% 1.9% Flu syndrome 3.2% 3.1% Rhinitis 3.2% 3.1% Myalgia 2.1% 0.4% Pediatric Patients 10 to 17 Years of Age In an 8-week double-blind, placebo-controlled study, boys and post-menarchal girls, 10 to 17 years of age, with HeFH (n=194), were treated with WELCHOL tablets (1.9-3.8 g, daily) or placebo tablets.

Table 2 Clinical Study of WELCHOL for Primary Hyperlipidemia in HeFH Pediatric Patients: Adverse Reactions Reported in ≥2% of Patients and More Commonly than in Placebo WELCHOL N=129 Placebo N=65 Nasopharyngitis 6.2% 4.6% Headache 3.9% 3.1% Fatigue 3.9% 1.5% Creatine Phosphokinase Increase 2.3% 0.0% Rhinitis 2.3% 0.0% Vomiting 2.3% 1.5% The reported adverse reactions during the additional 18-week open-label treatment period with WELCHOL 3.8 g per day were similar to those during the double-blind period and included headache (7.6%), nasopharyngitis (5.4%), upper respiratory tract infection (4.9%), influenza (3.8%), and nausea (3.8%).

Type 2 Diabetes Mellitus In 5 add-on combination and 1 monotherapy double-blind, 12- to 26-week, placebo-controlled clinical trials in patients with type 2 diabetes mellitus, 1022 patients were treated with WELCHOL. The mean exposure duration was 20 weeks (total exposure 393 patient-years). Patients were to receive 3.8 grams of WELCHOL per day.

The mean age of patients was 55.7 years, 52.8 percent of the population was male and 61.9% were Caucasian, 4.8% were Asian, and 15.9% were Black or African American. At baseline the population had a mean hemoglobin A1c (HbA1c) of 8.2%, and 26% had past medical history suggestive of microvascular complications of diabetes. Table 3 shows adverse reactions associated with the use of WELCHOL in patients with type 2 diabetes.

These adverse reactions were not present at baseline, occurred more commonly on WELCHOL than on placebo, and occurred in at least 2% of patients treated with WELCHOL.

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary WELCHOL is not absorbed systemically following oral administration, and maternal use is not expected to result in fetal exposure to the drug. Limited available data on the use of WELCHOL are insufficient to determine a drug-associated risk of major congenital malformations or miscarriage. In animal reproduction studies, no evidence of either maternal or fetal toxicity was found in rats or rabbits exposed to colesevelam hydrochloride during the period of fetal organogenesis at 8 and 5 times, respectively, the maximum recommended human dose (MRHD) of 3.75 g/day, based on body surface area (mg/m 2 ).

No adverse effects on offspring survival and development were observed in rats administered 5 times the MRHD (see Data ). WELCHOL may decrease the absorption of fat-soluble vitamins [see Warnings and Precautions (5.3) ]. There are no data available on the effect of colesevelam hydrochloride on the absorption of fat-soluble vitamins in pregnant women.

If the patient becomes pregnant while taking WELCHOL, the patient should be advised of the lack of known clinical benefit with continued use during pregnancy. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data Human Data There are no adequate and well-controlled studies of colesevelam hydrochloride use in pregnant women. In the postmarketing setting there have been infrequent reports of pregnancy with use of WELCHOL and a causal association with congenital anomalies has not been established. Animal Data In pregnant rats given dietary doses of 0.3, 1.0, 3.0 g/kg/day colesevelam hydrochloride from gestation days 7 through 17, no teratogenic effects were observed.

Exposures at 3.0 g/kg/day were 8 times the human exposure at 3.75 g/day MRHD, based on body surface area (mg/m 2 ). In pregnant rabbits given oral gavage doses of 0.1, 0.5, 1.0 g/kg/day colesevelam hydrochloride from gestation days 6 through 18, no teratogenic effects were observed. Exposures at 1.0 g/kg/day were 5 times the human exposure at 3.75 g/day MRHD, based on body surface area (mg/m 2 ).

In pregnant rats given oral gavage doses of 0.1, 0.3, 1.0 g/kg/day colesevelam hydrochloride from gestation day 6 through lactation day 21 (weaning), no adverse effects on survival and development were observed. Exposures at 1.0 g/kg/day were 5 times the human exposure at 3.75 g/day MRHD, based on body surface area (mg/m 2 ).

8.2Lactation Risk Summary WELCHOL is not absorbed systemically by the mother following oral administration, and breastfeeding is not expected to result in exposure of the child to WELCHOL.

8.3Females and Males of Reproductive Potential Contraception Use of WELCHOL may reduce the efficacy of oral contraceptives. Advise patients to take oral contraceptives at least 4 hours prior to taking WELCHOL [see Drug Interactions (7) ].

8.4Pediatric Use Primary Hyperlipidemia The safety and effectiveness of WELCHOL to reduce LDL-C levels in boys and postmenarchal girls 10 to 17 years of age with HeFH who are unable to reach LDL-C target levels despite an adequate trial of dietary therapy and lifestyle modification have been established. Use of WELCHOL for this indication is supported by a study in 129 WELCHOL-treated pediatric patients aged 10 to 17 years with HeFH [see Clinical Studies (14.1) ] . Adverse reactions commonly observed in pediatric patients compared to placebo, but not in adults, included headache (3.9%), creatine phosphokinase increase (2.3%), and vomiting (2.3%) [see Adverse Reactions (6.1) ] .

🧓 Geriatric Use 138 words

8.5Geriatric Use Primary Hyperlipidemia Of the 1350 patients enrolled in the hyperlipidemia clinical studies, 349 (26%) were ≥65 years old, and 58 (4%) were ≥75 years old. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Type 2 Diabetes Mellitus Of the 2048 patients enrolled in the six diabetes studies, 397 (19%) were ≥65 years old, and 36 (2%) were ≥75 years old.

In these trials, WELCHOL 3.8 g/day or placebo was added onto background anti-diabetic therapy. No overall differences in safety or effectiveness were observed between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Primary Hyperlipidemia : Colesevelam hydrochloride, the active pharmaceutical ingredient in WELCHOL, is a non-absorbed, lipid-lowering polymer that binds bile acids in the intestine, impeding their reabsorption. As the bile acid pool becomes depleted, the hepatic enzyme, cholesterol 7-α-hydroxylase, is upregulated, which increases the conversion of cholesterol to bile acids. This causes an increased demand for cholesterol in the liver cells, resulting in the dual effect of increasing transcription and activity of the cholesterol biosynthetic enzyme, HMG-CoA reductase, and increasing the number of hepatic LDL receptors.

These compensatory effects result in increased clearance of LDL-C from the blood, resulting in decreased serum LDL-C levels. Serum TG levels may increase or remain unchanged. Type 2 Diabetes Mellitus : The mechanism by which WELCHOL improves glycemic control is unknown.

12.2Pharmacodynamics A maximum therapeutic response to the lipid-lowering effects of WELCHOL was achieved within 2 weeks and was maintained during long-term therapy. In the diabetes clinical studies, a therapeutic response to WELCHOL, as reflected by a reduction in HbA1c, was initially noted following 4-6 weeks of treatment and reached maximal or near-maximal effect after 12-18 weeks of treatment.

12.3Pharmacokinetics Absorption Colesevelam hydrochloride is a hydrophilic, water-insoluble polymer that is not hydrolyzed by digestive enzymes and is not absorbed. Distribution Colesevelam hydrochloride is not absorbed, and therefore, its distribution is limited to the gastrointestinal tract. Elimination Metabolism Colesevelam hydrochloride is not metabolized systemically and does not interfere with systemic drug-metabolizing enzymes such as cytochrome P450.

Excretion In 16 healthy volunteers, an average of 0.05% of administered radioactivity from a single 14 C-labeled colesevelam hydrochloride dose was excreted in the urine. Drug Interaction Studies Drug interactions between colesevelam and concomitantly administered drugs were screened through in vitro studies and confirmed in in vivo studies. In vitro studies demonstrated that cephalexin, metformin, and ciprofloxacin had negligible binding to colesevelam hydrochloride.

Therefore, an in vivo pharmacokinetic interaction of WELCHOL with these drugs is unlikely. WELCHOL was found to have no significant effect on the bioavailability of aspirin, atenolol, digoxin, enalapril, fenofibrate, lovastatin, metoprolol, phenytoin, pioglitazone, quinidine, rosiglitazone, sitagliptin, valproic acid, and warfarin. The results of additional in vivo drug interactions of WELCHOL are presented in Table 6.

📋 Description ~2 min read

11 DESCRIPTION WELCHOL (colesevelam hydrochloride) is a non-absorbed, polymeric, lipid-lowering and glucose-lowering agent for oral administration. Colesevelam hydrochloride is a high-capacity bile acid-binding molecule. Colesevelam hydrochloride is poly(allylamine hydrochloride) cross-linked with epichlorohydrin and alkylated with 1-bromodecane and (6-bromohexyl)-trimethylammonium bromide.

The chemical name (IUPAC) of colesevelam hydrochloride is allylamine polymer with 1-chloro-2,3-epoxypropane, [6-(allylamino)-hexyl]trimethylammonium chloride and N-allyldecylamine, hydrochloride. The chemical structure of colesevelam hydrochloride is represented by the following formula: wherein (a) represents allyl amine monomer units that have not been alkylated by either of the 1-bromodecane or (6-bromohexyl)-trimethylammonium bromide alkylating agents or cross-linked by epichlorohydrin; (b) represents allyl amine units that have undergone cross-linking with epichlorohydrin; (c) represents allyl amine units that have been alkylated with a decyl group; (d) represents allyl amine units that have been alkylated with a (6-trimethylammonium) hexyl group, and m represents a number ≥100 to indicate an extended polymer network.

A small amount of the amines are dialkylated and are not depicted in the formula above. No regular order of the groups is implied by the structure; cross-linking and alkylation are expected to occur randomly along the polymer chains. A large amount of the amines are protonated.

The polymer is depicted in the hydrochloride form; a small amount of the halides are bromide. Colesevelam hydrochloride is hydrophilic and insoluble in water. WELCHOL tablets are off-white, oval, film-coated, solid tablets each containing 625 mg colesevelam hydrochloride.

In addition, each tablet contains the following inactive ingredients: magnesium stearate, microcrystalline cellulose, silicon dioxide, HPMC (hydroxypropyl methylcellulose), and acetylated monoglyceride. The tablets are imprinted using a water-soluble black ink (<5 calories per 6 tablets). WELCHOL for oral suspension is a citrus-flavored, white to pale yellow powder containing yellow granules packaged in a packet containing 3.75 gram colesevelam hydrochloride.

In addition, each packet contains the following inactive ingredients: lemon flavor, orange flavor, propylene glycol alginate, simethicone, aspartame, citric acid, medium chain triglycerides, and magnesium trisilicate (<5 calories per 3.75 gram single-dose packet). PHENYLKETONURICS: WELCHOL for oral suspension contains 27 mg phenylalanine per 3.75 gram dose. Chemical Structure
