The long-term use of Colestyramine Powder
may cause:

prescribe vitamin K to help prevent this
• hyperchloraemic acidosis (acidic blood)
particularly in children and smaller patients
or if you have a kidney disorder or if you are
volume depleted (dehydrated)

Important Information about some of the
Ingredients of Colestyramine Powder
Colestyramine Powder contains Sunset Yellow
(E110) and Aspartame. Sunset Yellow may
cause allergic reactions. Aspartame is a source
of phenylalanine, which may be harmful for
people with phenylketonuria.

Colestyramine Powder is a sachet containing 4 g
of the active ingredient colestyramine.
Colestyramine is used to lower your body's
level of cholesterol (a type of fat). Colestyramine
works in the digestive tract to absorb the
cholesterol-containing bile acids, which then
pass out through the body in the faeces.
Colestyramine Powder is used to:
• Prevent heart disease in men aged
35-59 years of age who have raised
cholesterol levels that have not been
reduced by dieting and other methods.
• Reduce cholesterol in patients who have
raised cholesterol levels, either alone or with
diet, exercise, or statins (other types of
cholesterol lowering drugs).
• Relieve pruritus (itching), a symptom in
patients with biliary cirrhosis or partial
obstruction (inflammation or blockage of the
bile duct in the liver).
• Relieve diarrhoea caused by: ileal resection
(removal of part of the ileum in the digestive
tract), Crohn's disease (inflammation of the
digestive tract), vagotomy (removal of a
nerve to reduce stomach acid), and diabetic
vagal neuropathy (disease of the same
nerve caused by diabetes).
Always take Colestyramine Powder exactly as
• Control of diarrhoea caused by radiation.
your doctor has told you. You should check with
your doctor or pharmacist if you are not sure.

• Your dose will be increased over 3-4 weeks
to the usual dose. The usual daily dose for
the prevention of heart disease and to reduce
cholesterol is 3-6 sachets (12 to 24 grams). The
maximum daily dose is 9 sachets (36 grams).
The daily dose can be taken in single or
divided doses up to 4 times a day.
• For the relief of diarrhoea, the usual daily
dose is 3-6 sachets (12 to 24 grams). If your
doctor has told you that you also suffer from
bile acid malabsorption (causing weight loss
and foul-smelling stools), and you have
seen no improvement in 3 days, talk to your
doctor, who will start another treatment.
• For the relief of pruritus, the usual daily
dose is 1-2 sachets (4-8 grams).
Children aged 6 to 12 years
The starting dose depends on the child's
weight. The adult dose is multiplied by the
child's weight (in kilograms) and divided by 70.

children under 6 years of age.
Patients may need a reduced dose.

your medicine. If you or someone else takes too
many sachets all together, contact your doctor,

easier identification of the medicine.

If you forget to take a dose, take it as soon as

make up for a forgotten dose if it is almost
time for your next dose.
