colesevelam hydrochloride: clinical details
Prescribing considerations
- Exclude and manage secondary causes of hypercholesterolaemia before initiation.
- Use caution with raised triglycerides, dysphagia, severe gastrointestinal motility disorders, inflammatory bowel disease, liver failure, major gastrointestinal surgery or significant constipation.
- Safety and efficacy have not been established in children and adolescents.
- Consider whether the tablet size and need to swallow it whole are suitable for the patient.
Contraindications and cautions
- Hypersensitivity to colesevelam hydrochloride or an excipient
- Bowel obstruction
- Biliary obstruction
Monitoring
- Check total cholesterol, LDL cholesterol and triglycerides to assess response and detect triglyceride elevation.
- Monitor anticoagulation closely with warfarin or similar agents.
- Monitor ciclosporin concentrations when colesevelam is started or stopped.
- For patients susceptible to malabsorption or deficiency, consider vitamins A, D and E and vitamin K status through coagulation parameters.
Clinical pharmacology
Colesevelam is a non-absorbed polymeric bile acid sequestrant. Interruption of enterohepatic bile acid recycling increases hepatic conversion of cholesterol to bile acids and LDL-receptor activity, increasing LDL clearance; triglycerides may rise.
Formulation and product differences
- The selected product is an off-white to light-yellow, capsule-shaped film-coated tablet.
- The tablets must remain intact and are supplied in a moisture-protective bottle containing an oxygen-absorber sachet.

colesevelam hydrochloride interactions
Colesevelam can bind medicines in the gut or otherwise alter their exposure. Confirm timing and monitoring requirements with a pharmacist or prescriber.
Levothyroxine
Colesevelam can reduce levothyroxine absorption.
Oral contraceptive pills
Taking them together can reduce hormone exposure.
Warfarin and similar anticoagulants
Reduced vitamin K absorption may alter anticoagulation, requiring closer monitoring.
Ciclosporin
Colesevelam lowers ciclosporin exposure; blood concentrations require monitoring when either medicine is started or stopped.
