What this medicine information covers
Colesevelam is a prescription-only medicine licensed for certain adults with primary hypercholesterolaemia, used alongside diet and in specified treatment arrangements with or without other cholesterol medicines. It is not a first-choice treatment for everyone with raised cholesterol. The prescriber decides the treatment plan. This guide does not recommend a medicine for another condition or encourage a new prescription.
Confirm both the tablet count and the days of supply
A pack quantity and a month's supply are not necessarily the same thing. The pharmacist needs the prescribed quantity and the current labelled directions to interpret an availability enquiry. If you have an older bottle at home, check its label date before copying details from it. Mention any named product on the current prescription rather than assuming that every colesevelam product can be supplied in the same way.
Details to check on your current prescription
- The medicine name and 625 mg tablet strength.
- Any brand or manufacturer's name specified on the prescription.
- The prescribed number of tablets and current labelled directions.
- The number of days left, rather than only whether a bottle is nearly empty.
- Who issued the prescription and whether it has already been sent to a pharmacy.
Keep the original wording available. You do not need to upload a prescription or disclose a diagnosis to read this guide. If records are needed for a pharmacy discussion, the team will explain how to provide them.
A repeat request is for the wrong quantity
A patient may copy the size of the last pack into a message even though the prescriber has changed the quantity. Start with the actual issued prescription, then explain how much remains. If the repeat list and label appear inconsistent, ask for clarification before supply is arranged. A pharmacy should not have to guess whether a request concerns a pack size, a daily tablet count or a new treatment instruction.
Organising the next repeat
If treatment comes from more than one prescribing team, keep an up-to-date medicine list for the pharmacist to check. When arranging collection or delivery, agree the deadline after the exact prescription has been identified. Questions about how medicines should be spaced belong in a pharmacist discussion: they should not be resolved by changing your routine based on a general online answer or a different-looking pack.
Safety and clinical advice
When a clinical conversation comes first
Constipation and wind are common adverse effects. Colesevelam can affect absorption of other medicines, including thyroid medicines, some anticoagulants and oral contraceptives. Ask the pharmacist about your actual medicine list and timing; do not adopt a universal spacing rule from this guide. Tell the prescriber about swallowing problems or significant bowel symptoms. Read the leaflet for the complete precautions.

Prescription questions people ask
Is colesevelam a medicine for everyone with high cholesterol?
No. The licensed treatment arrangements are specific and the prescriber must assess suitability. The fact that a medicine is listed here is not a treatment recommendation.
Can this page tell me how to space colesevelam and my other medicines?
Not individually. Ask the pharmacist to review your actual medicines, including non-prescription products, before changing timings.
Does a large pack always last a month?
No. Days of supply depend on your current prescribed directions. Give the pharmacy both the quantity and the label details.
Can I change the quantity to reduce delivery frequency?
The supply must follow an appropriate prescription. Discuss any practical difficulty with the pharmacist and prescriber rather than changing the request yourself.
My specialist prescribed it for a reason not discussed here. What should I do?
Follow the agreed clinical plan and ask your specialist about that use. This page deliberately describes licensed product information and does not replace their advice.
Can I make an enquiry before changing my nominated pharmacy?
Yes. Asking a question does not change your nomination or move an existing prescription.
UK prescription questions
Understanding supply and repeat arrangements in the UK
A UK colesevelam prescription enquiry
Have the strength, form and prescribed quantity from your current label available. Tell the pharmacy whether a repeat is awaiting authorisation, has been issued or is already being prepared elsewhere. These situations need different next steps, even if the medicine name in the enquiry is the same.
Keep the care plan with the supply discussion
People may arrive here after discussions with different clinical teams. This page cannot establish the reason for your prescription or advise a treatment change. For a supply problem, agree who is checking availability and when they will update you. Questions about use, tolerability or taking it alongside other medicines should go to your pharmacist or prescriber.
