About Cholestyramine 5g Sachet
Buy Cholestyramine 5 g Sachet online. Each sachet contains 5 g of cholestyramine resin, a bile acid sequestrant used to lower high cholesterol, relieve itching caused by a partial blockage of the bile ducts and treat diarrhoea caused by bile acids. It contains the same active ingredient as the reference brands Questran and Prevalite. In the USA and UK it is a prescription medicine, so a valid prescription is needed for your order. See today's price above and add it to your cart.
The powder is mixed with water or another drink and is not absorbed into the body. It works inside the gut, so it can also bind other medicines, and timing matters. Approved uses and legal status differ between countries, so this page covers the USA, UK, Australia, the UAE and Russia.

How it works
Cholestyramine is a resin that is not absorbed into the blood. In the gut it binds bile acids and carries them out in the stool. To replace the lost bile acids, the liver uses cholesterol from the blood, so LDL cholesterol falls. Binding bile acids in the bowel also reduces itching and diarrhoea caused by bile acids.
Uses
High cholesterol: cholestyramine is used alongside diet to lower raised LDL cholesterol, particularly when a statin alone is not enough or is not suitable.
Itching from bile duct blockage: in partial biliary obstruction, bile acids build up in the skin and cause itching. Cholestyramine binds them in the gut and eases the itch.
Bile acid diarrhoea: it is used for diarrhoea caused by too many bile acids reaching the bowel, for example after surgery on the ileum or in Crohn's disease. It is also used in specialist care to speed removal of leflunomide and teriflunomide from the body.
Dosage and how to take it
Empty each 4 g sachet into a glass or cup, add about 150 ml of water, juice or another drink, stir well and drink. Never take the powder dry, as it can be inhaled or cause a blockage. You can also mix it into soft food such as apple sauce. Take it with meals as directed.
The UK product information describes a starting dose of 4 g a day for high cholesterol, which is increased gradually to the dose your prescriber chooses, usually divided into one or two doses. The US label describes a similar build-up. Take other medicines at least one hour before or four to six hours after cholestyramine, as it can bind them. Always follow the leaflet in the pack and the advice of your prescriber or pharmacist.
Storage Instructions
Store the sachets in their original pack at room temperature, away from moisture, following any instructions on the pack. Keep out of the reach of children and do not use after the expiry date. Use a mixed dose straight away.
Possible side effects
- Constipation
- Bloating and wind
- Stomach discomfort or pain
- Nausea or vomiting
- Heartburn or indigestion
- Diarrhoea
- Loss of appetite
- Rash or skin irritation
- Gritty or unpleasant taste
Seek urgent medical help for severe stomach pain, constipation that does not clear, black or bloody stools, unusual bleeding or bruising, or swelling of the face, lips or throat. Long-term use can lower levels of vitamins A, D, E and K, so your doctor may advise supplements.
Safety
- Mix with liquid: never swallow the powder dry. Take it with plenty of fluid.
- Other medicines: cholestyramine reduces absorption of many medicines, including warfarin, digoxin, thyroxine, thiazide diuretics, propranolol and the contraceptive pill. Take them at least one hour before or four to six hours after the sachet.
- Biliary obstruction: do not use if there is a complete blockage of the bile ducts.
- Constipation: drink plenty of fluids, eat enough fibre and tell your doctor if you are very constipated, as it can worsen haemorrhoids or bowel problems.
- Vitamin levels: long-term use can cause low levels of fat-soluble vitamins and, rarely, bleeding. Your doctor may check your blood.
- Triglycerides: cholestyramine can raise triglycerides. It is not suitable if you have very high triglycerides.
- Pregnancy and breastfeeding: the medicine is not absorbed, but vitamin levels matter. Ask your prescriber before use.
- Allergy and phenylketonuria: do not use if you are allergic to cholestyramine. Check whether your product contains aspartame.
- Children: use only on a doctor's advice, with the dose set by weight.

How do I buy cholestyramine sachets online?

How do I take cholestyramine powder?
Empty the sachet into a glass, add about 150 ml of water or juice, stir and drink, or mix it into soft food. Never take it dry. Take it with meals as directed, and keep other medicines apart from it.
Why do I need to separate cholestyramine from other medicines?
Cholestyramine can bind other medicines in the gut and stop them being absorbed. Take other medicines at least one hour before, or four to six hours after, the sachet. Your pharmacist can plan the timing with you.
How long does cholestyramine take to lower cholesterol?
Cholesterol usually starts to fall within a few weeks, and the full effect may take a month or longer. Itching and diarrhoea can improve within days to a couple of weeks. Keep taking it as prescribed.
Does cholestyramine cause constipation?
Yes, constipation is the most common side effect. Drinking plenty of fluids and eating enough fibre helps. The dose is usually built up slowly. Tell your prescriber if constipation is severe or does not settle.
Can I take cholestyramine with warfarin or the contraceptive pill?
These medicines can be bound by cholestyramine, so timing is important. Take them at least one hour before or four to six hours after the sachet. Tell your prescriber, who may adjust doses or arrange extra checks.
Is cholestyramine safe long term?
It is used for long periods, but vitamin levels may fall, so your doctor may check your blood and advise supplements. Do not stop or change your treatment without your prescriber's advice.
