It is available as a powder for oral suspension, which must be mixed with water or other fluids before consumption. The most commonly reported side effect of cholestyramine is constipation.
Cholestyramine may also cause other side effects, including muscle pain. However, muscle pain is less common than other adverse reactions such as abdominal discomfort, flatulence, nausea, vomiting, and diarrhoea.

Other less common side effects include tongue irritation, irritation of the perianal area, abdominal pain, bloating, belching, gallstones, weight loss, excessive gas, and discoloured teeth.

It may also cause allergic reactions, including severe constipation
Cholestyramine is a medication used to treat high cholesterol and itching due to partial bile obstruction. It works by increasing bile acid removal from the body, thereby decreasing cholesterol levels. While cholestyramine can be an effective treatment, it may cause certain side effects, including allergic reactions and constipation.
Allergic reactions to cholestyramine can be serious and require immediate medical attention. Symptoms of a severe allergic reaction may include hives, difficulty breathing, and swelling of the face, lips, tongue, or throat. If you experience any of these symptoms, it is crucial to stop taking cholestyramine and seek medical help right away.
Constipation is a common side effect of cholestyramine. It is more likely to occur in older adults and individuals taking higher doses of the medication. To prevent and manage constipation, it is recommended to stay hydrated, increase fibre intake, and follow the prescribed dosing schedule. Severe constipation can lead to hospitalisation and may worsen haemorrhoids.
In addition to allergic reactions and constipation, cholestyramine may cause other side effects. These can include teeth discolouration, enamel erosion, tongue irritation, abdominal discomfort, nausea, and weight changes. Some animal studies have suggested that cholestyramine may cause tumours, but its effect on humans is unknown. It is important to consult a healthcare professional before taking cholestyramine to weigh the benefits against the potential risks and side effects.

Cholestyramine can cause high acid levels, which can lead to nausea and vomiting
Cholestyramine is a medication used to treat high cholesterol and relieve itching caused by bile duct blockage. It works by increasing bile acid removal from the body, thereby reducing cholesterol levels. While cholestyramine is effective in lowering cholesterol, it can also cause various side effects, one of which is high acid levels.
High acid levels can occur as a less common side effect of cholestyramine, affecting 0.1% to 1% of people taking the medication. This condition, known as hyperchloremic acidosis, can lead to an array of unpleasant symptoms, including nausea and vomiting.
Nausea is a common symptom of hyperchloremic acidosis, and it can range from mild discomfort to a more severe and persistent feeling of sickness. It can be accompanied by other gastrointestinal issues such as abdominal pain, bloating, and diarrhoea, all of which are known side effects of cholestyramine.
Vomiting is another potential consequence of high acid levels induced by cholestyramine. It can be sporadic or frequent and may be accompanied by other symptoms such as dizziness and chest pain. In some cases, vomiting may be a sign of a more serious reaction to the medication.
It is important to consult a healthcare professional if you experience any of these side effects, especially if they persist or become severe. They may recommend adjusting the dosage or provide guidance on managing these side effects. Additionally, staying adequately hydrated and consuming enough fibre can help alleviate some of these issues.

It may interfere with the absorption of vitamins K, A, and D, and folate
Cholestyramine is a prescription drug used to treat high cholesterol and itching caused by partial bile obstruction. It is available as a powder for oral suspension and should always be mixed with water or other fluids before consumption.
Cholestyramine works by increasing bile acid removal from the body. Bile acid is produced by the liver and helps with food digestion. Removing bile acid also decreases cholesterol levels in the body.
Cholestyramine may interfere with the absorption of certain vitamins, including vitamins K, A, and D, as well as folate (a form of vitamin B). Low levels of these vitamins can have negative health consequences. For example, vitamin K deficiency can lead to bleeding tendencies and an increased risk of bruising. Vitamin A deficiency can result in night blindness, while vitamin D deficiency can cause osteoporosis. Folate deficiency can lead to changes in red blood cells and cause anemia.
It is important for individuals taking cholestyramine to be aware of these potential vitamin deficiencies. Consulting with a healthcare provider is essential to determine if additional vitamin supplementation is necessary to maintain adequate vitamin levels in the body.
