Chenodeoxycholic Acid is a medication used to dissolve certain types of gallstones and treat liver and bile-related conditions. It works by reducing cholesterol production in the liver and increasing bile flow. This bile acid treatment is commonly prescribed for gallstones, cholestatic liver disease, and primary biliary cholangitis. Always consult your healthcare provider before starting or adjusting your dosage.

Administration Instructions for Chenodeoxycholic Acid
Take Chenodeoxycholic Acid with food to reduce the risk of stomach upset. Swallow the tablet whole with a glass of water. Do not crush or chew the tablet. If you miss a dose, take it as soon as you remember, but skip it if it’s almost time for your next dose. Do not double up on doses. Always follow your doctor’s instructions carefully.
Contraindications for Chenodeoxycholic Acid
A contraindication is a specific condition where a medication should not be used because it may cause harm. It’s important to know if you have any contraindications before starting a new medication. Below are the contraindications for Chenodeoxycholic Acid:
Liver Disease: If you have severe liver disease, taking Chenodeoxycholic Acid can worsen liver function and lead to serious complications. This medication is processed by the liver, and if the liver is not functioning properly, it can cause toxicity.
Gallbladder Issues: Patients with a non-functioning gallbladder or gallbladder obstruction should not take Chenodeoxycholic Acid. It works by dissolving gallstones, but if your gallbladder is not functioning, the medication will not be effective and may cause harm.
Pregnancy: Chenodeoxycholic Acid is contraindicated during pregnancy because it may harm the developing fetus. It is classified as a Category X medication, meaning it should not be used during pregnancy.
Allergy to Chenodeoxycholic Acid: If you have had an allergic reaction to Chenodeoxycholic Acid or any of its ingredients, you should not take this medication. Allergic reactions can range from mild to severe, including anaphylaxis.
Drug to Drug Interactions
Chenodeoxycholic Acid can interact with other medications, which may reduce its effectiveness or increase the risk of side effects. Be sure to inform your healthcare provider of all the medications you are taking. Below are some known drug interactions:
Cholestyramine (Questran): Cholestyramine can bind to Chenodeoxycholic Acid in the intestines, reducing its absorption and effectiveness.
Colestipol (Colestid): Like cholestyramine, colestipol can interfere with the absorption of Chenodeoxycholic Acid, making it less effective.
Aluminum-based antacids (Maalox, Gaviscon): These antacids can reduce the absorption of Chenodeoxycholic Acid, decreasing its ability to dissolve gallstones.
Estrogen-containing medications (birth control pills, hormone replacement therapy): Estrogen can increase cholesterol levels in bile, which may counteract the effects of Chenodeoxycholic Acid in dissolving gallstones.
Chenodeoxycholic Acid in Pregnancy
Is it safe to take Chenodeoxycholic Acid when pregnant?
No, Chenodeoxycholic Acid is not considered safe during pregnancy. It is classified as a Category X medication, which means it has been shown to cause harm to the developing fetus and should not be used by pregnant women. If you are pregnant or planning to become pregnant, it is essential to consult with one of our healthcare providers through telemedicine to discuss safer alternatives.
Chenodeoxycholic Acid while Breastfeeding
Is it safe to take Chenodeoxycholic Acid while breastfeeding?
There is limited information on whether Chenodeoxycholic Acid passes into breast milk. Due to the lack of sufficient studies, it is generally recommended to avoid using this medication while breastfeeding. If you are breastfeeding and require treatment, consult one of our healthcare providers to explore safer options for you and your baby.
Estimated Cost of Chenodeoxycholic Acid
The cost of a 30-day supply of Chenodeoxycholic Acid can vary depending on your location and the pharmacy you use. Without insurance, the estimated cost with a GoodRX coupon typically ranges from $1,000 to $1,500 for a 30-day supply. It’s always a good idea to check with your local pharmacy for the most accurate pricing.
Possible Alternatives to Chenodeoxycholic Acid
If Chenodeoxycholic Acid is not suitable for you, there are alternative treatments and lifestyle changes that may help manage your condition. It’s important to discuss these alternatives with your healthcare provider before making any changes to your treatment plan. Our telemedicine providers are available to help you explore these options.
Gallstones
Alternatives include ursodeoxycholic acid (Actigall) or surgical removal of the gallbladder (cholecystectomy). Dietary adjustments, such as reducing fat intake, may also help prevent the formation of gallstones.
Cholestatic Liver Disease
Ursodeoxycholic acid is often used as an alternative treatment. In more advanced cases, a liver transplant may be necessary. Lifestyle changes, such as avoiding alcohol and maintaining a healthy weight, can also be beneficial in managing the condition.
Primary Biliary Cholangitis
Ursodeoxycholic acid is typically the first-line treatment for this condition. Obeticholic acid (Ocaliva) may also be prescribed in some cases. Lifestyle modifications, including a low-sodium diet and regular exercise, can help manage symptoms and improve overall health.
Familial Hypercholesterolemia
Statins (e.g., atorvastatin, simvastatin) are commonly prescribed to lower cholesterol levels. Dietary changes, such as reducing saturated fats and increasing fiber intake, can also play a significant role in managing cholesterol levels.
Bile Acid Malabsorption
Cholestyramine (Questran) or colesevelam (Welchol) may be used to manage symptoms of bile acid malabsorption. Additionally, following a low-fat diet can help reduce symptoms and improve quality of life.
Nonalcoholic Fatty Liver Disease
Weight loss, regular physical activity, and a healthy diet are the primary treatments for nonalcoholic fatty liver disease. In some cases, medications such as pioglitazone or vitamin E may be prescribed to help manage the condition.
Cholesterol Gallstones
Ursodeoxycholic acid or surgical removal of the gallbladder may be considered as treatment options. Reducing cholesterol intake through dietary changes can also help prevent the formation of gallstones.
Liver Cirrhosis
Treatment for liver cirrhosis focuses on managing symptoms and preventing complications. This may include medications to reduce fluid buildup, avoiding alcohol, and maintaining a healthy diet. In severe cases, a liver transplant may be necessary.
Hyperlipidemia
Statins, fibrates, and niacin are commonly used to manage high cholesterol levels. Dietary changes, such as reducing saturated fats and increasing fiber intake, are also important in controlling cholesterol levels.
Cystic Fibrosis
For individuals with cystic fibrosis, pancreatic enzyme supplements and a high-calorie diet are often recommended to manage symptoms. Ursodeoxycholic acid may also be used to improve liver function in patients with cystic fibrosis-related liver disease.
Recent Updates on Chenodeoxycholic Acid Research
Recent studies are investigating the potential use of Chenodeoxycholic Acid in treating other liver-related conditions beyond gallstones. Researchers are exploring its role in managing certain types of cholestatic liver diseases and bile acid malabsorption. However, more clinical trials are needed to confirm its safety and effectiveness in these areas.
Additionally, ongoing research is examining the combination of Chenodeoxycholic Acid with other bile acids, such as ursodeoxycholic acid, to improve treatment outcomes for patients with complex liver conditions. As new findings emerge, it’s important to stay informed and discuss any potential changes to your treatment with your healthcare provider. If you have questions about the latest research, our telemedicine providers are available to help you understand how these developments may impact your care.
