Bile acids are created in the liver,&nbsp; using cholesterol as a primary building block. The acids are secreted into the intestines to help the body digest and absorb fats from food. Once they have completed their task, bile acids are reabsorbed and returned to the liver for reuse.<\/p>\n\n\n\n<p>By binding to (or sequestering) the bile acids, colesevelam creates a large molecular cluster that is too large for the bloodstream to reabsorb. Instead, the cluster passes through the stool. When the liver senses a shortage in bile acids, cholesterol is pulled out of the bloodstream to produce more acids. This process helps lower the concentration of cholesterol in the patient&#8217;s blood.&nbsp;<\/p>\n\n\n\n<p>Colesevelam&#8217;s role in managing high blood sugar is less well defined, though current research suggests the drug signals glucagon-like peptide-1 (GLP-1) and other gut peptides. By influencing these pathways, colesevelam helps the body regulate insulin secretion after meals and improves blood sugar levels over time.<\/p>\n\n\n\n<div class=\"quick-facts-card\">\n  <table class=\"quick-facts-table\">\n    <colgroup>\n      <col\/>\n      <col\/>\n    <\/colgroup>\n\n    <thead>\n      <tr>\n        <th colspan=\"2\">Quick Facts<\/th>\n      <\/tr>\n    <\/thead>\n\n    <tbody>\n      <tr>\n        <td><strong>Common Brands<\/strong><\/td>\n        <td>Welchol<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Drug Class<\/strong><\/td>\n        <td>Bile acid sequestrant (bile acid resin)<\/td>\n      <\/tr>\n\n      <tr>\n        <td><strong>Generic Status<\/strong><\/td>\n        <td>Generic version available<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Availability<\/strong><\/td>\n        <td>Prescription only<\/td>\n    <\/tbody>\n  <\/table>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-dosing\">Dosing<\/h2>\n\n\n\n<p>Per standard guidelines, colesevelam requires consistency to maintain sufficient levels to sequester bile acid throughout the day. Colesevelam comes as an oral tablet or powder.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Oral tablets: <\/strong>Standard guidelines suggest a daily dosage of 3.75 grams. Guidelines state that you should swallow the tablets whole.<\/li>\n\n\n\n<li><strong>Oral suspension: <\/strong>As with the oral tablet, the recommended daily dosage for colesevelam oral suspension is 3.75 grams. Patients can get the dosage they need by mixing one 3.75-gram powder packet once daily. Mix the powder with water, fruit juice, or a diet soft drink.<\/li>\n\n\n\n<li><strong>Dosage timing: <\/strong>Take each colesevelam dose with a meal and 8 ounces of liquid. This method helps ensure the medication moves through the digestive system and reduces the risk of an upset stomach.<\/li>\n<\/ul>\n\n\n\n<p><em><strong>Note:<\/strong> Dosing information below is educational only.

Serious side effects from taking colesevelam can include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hypertriglyceridemia: <\/strong>In some patients, colesevelam can cause triglyceride levels to increase rather than stabilize. For this reason, providers generally avoid recommending the medication for people whose triglyceride levels are already high.<\/li>\n\n\n\n<li><strong>Pancreatitis: <\/strong>An excessive spike in triglyceride levels after taking colesevelam can trigger severe pancreatic inflammation. Symptoms include severe abdominal pain that radiates to the back, with or without\u00a0 nausea and vomiting.<\/li>\n\n\n\n<li><strong>Bowel obstruction: <\/strong>Since the medication creates a bulky mass from binding to bile acid, those with a history of bowel surgery or severe constipation are at a higher risk of developing bowel blockage if they take colesevelam. Symptoms include the inability to pass gas or stool and a hard, swollen abdomen.<\/li>\n\n\n\n<li><strong>Vitamin deficiency: <\/strong>By binding to bile acids, colesevelam can indirectly interfere with the absorption of fat-soluble vitamins such as vitamins A, D, E, and K.<\/li>\n<\/ul>\n\n<\/div>\n\n\n\n<p class=\"has-muted-color has-text-color\" style=\"font-size:0.875rem\"><em>Call your doctor immediately if you experience any concerning or prolonged symptoms.<\/em><\/p>\n\n\t<\/div>\n<\/section>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pharmacist-tips\">Pharmacist Tips<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-follow-the-4-hour-rule-for-other-medications\">Follow The 4-Hour Rule For Other Medications<\/h3>\n\n\n\n<p>Standard guidelines recommend that patients take many other oral medications at least 4 hours before their colesevelam dose. By binding the bile acids in the gut, colesevelam can accidentally trap other medications and prevent them from working properly. Check with your pharmacist or doctor if you are taking other medications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-hydration-is-key\">Hydration Is Key<\/h3>\n\n\n\n<p>To reduce the risk of constipation, patients are advised to drink plenty of water throughout the day while taking colesevelam.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-fiber-is-your-friend\">Fiber Is Your Friend<\/h3>\n\n\n\n<p>Incorporating more fiber into your diet can help your digestive tract functions efficiently while you&#8217;re taking colesevelam.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-some-mixers-work-better-than-others\">Some Mixers Work Better Than Others<\/h3>\n\n\n\n<p>If you are using colesevelam oral powder, mixing with hot liquids or carbonated beverages can produce an unpleasant aftertaste. Many patients find that chilled fruit juice is more palatable because it masks the gritty texture of the powder.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-check-the-label\">Check the Label<\/h3>\n\n\n\n<p>Some forms of colesevelam contain aspartame, which breaks down into the amino acid phenylalanine. People with phenylketonuria are unable to break down phenylalanine, so they should check with their pharmacist to ensure the colesevelam formulation they choose is safe for them to consume.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-drug-interactions\">Drug Interactions<\/h2>\n\n\n\n<p>Colesevelam binds to many things it encounters in the intestine. This significantly increases the chances of interaction with other medications. Known interactions with colesevelam include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Thyroid medications: <\/strong>Colesevelam can easily bind to levothyroxine and other thyroid hormones. This can lead to hypothyroidism if the doses of these medications are not separated.<\/li>\n\n\n\n<li><strong>Oral birth control: <\/strong>If taken too close to a colesevelam dose, some oral contraceptives may lose their effectiveness.<\/li>\n\n\n\n<li><strong>Diabetes medications: <\/strong>Although colesevelam can help manage high blood sugar, it can also interfere with the absorption of diabetes medications like glimepiride and glipizide.<\/li>\n\n\n\n<li><strong>Blood thinners: <\/strong>Colesevelam can affect levels of blood thinners like warfarin, which may necessitate more frequent blood monitoring from a medical provider.<\/li>\n\n\n\n<li><strong>Vitamins: <\/strong>Per standard guidelines, you should take multivitamins and supplements containing fat-soluble vitamins at least 4 hours before taking colesevelam. This timing helps your body properly absorb the vitamins.<\/li>\n<\/ul>\n\n\n\n<p>Always give your doctor and pharmacist a complete list of all your medications, vitamins, and supplements to check for potential interactions.<\/p>\n\n\n\n<section class=\"telyrx-faq-section\" data-toc-title=\"FAQs\">\n\t<h2 class=\"telyrx-faq-heading\">FAQs<\/h2>\n\t\t<div class=\"telyrx-faq-items\">\n\t\t\n\n<details class=\"telyrx-faq-item\">\n\t<summary class=\"telyrx-faq-question\">\n\t\t<span class=\"telyrx-faq-question-text\">Why did my doctor prescribe a cholesterol drug to help lower my blood sugar for type 2 diabetes?<\/span>\n\t\t<svg class=\"telyrx-faq-chevron\" width=\"20\" height=\"20\" viewBox=\"0 0 20 20\" fill=\"none\" aria-hidden=\"true\">\n\t\t\t<path d=\"M5 7.5L10 12.5L15 7.5\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\/>\n\t\t<\/svg>\n\t<\/summary>\n\t<div class=\"telyrx-faq-answer\">\n\t\t\n\n<p>Colesevelam has a unique dual-action mechanism that makes it effective for both lowering cholesterol and managing high blood sugar in people with type 2 diabetes.
