A: Stener® is a medication containing Ursodeoxycholic Acid, a naturally occurring bile acid. It is used to treat primary biliary cirrhosis, a condition that causes damage to the bile ducts in the liver. Stener® is also effective in dissolving radiolucent cholesterol gallstones in patients who have a functioning gallbladder. However, it is not suitable for all types of gallstones, such as those that are radio-opaque.

A: For Primary Biliary Cirrhosis: The recommended dosage is 13–15 mg per kilogram of body weight per day, divided into four doses. It should be taken with food for the best absorption and to minimize stomach upset. For Dissolving Gallstones: The recommended dosage is 6–12 mg per kilogram of body weight per day. You can take it as a single nighttime dose or divide it into smaller doses throughout the day, based on your doctor’s advice. Your doctor will determine the exact dosage depending on your condition and weight. Always follow their instructions closely.

A: Stener® is not suitable for everyone. You should not take it if: You are allergic to Ursodeoxycholic Acid or any of the ingredients in Stener®. You have gallstones that are radio-opaque (visible on X-rays) or if your gallbladder is not functioning. Always inform your doctor about your full medical history before starting this medication.

A: There are no adequate studies on the use of Stener® in pregnant women, so it should only be used during pregnancy if clearly necessary. If you are pregnant or planning to become pregnant, consult your doctor to weigh the benefits and risks. For breastfeeding mothers, it is not known whether Stener® passes into breast milk. If you need to take this medication while nursing, your doctor may advise you to stop breastfeeding or monitor your baby closely.

A: While Stener® is generally well-tolerated, some patients may experience side effects, including: Common side effects: Nausea, vomiting, diarrhea, and pruritus (itching). Rare side effects: Calcification (hardening) of gallstones, which may affect treatment effectiveness. If you notice severe or unusual side effects, contact your doctor immediately.

A: Yes, Stener® can interact with certain medications. For example: Oestrogenic hormones and contraceptives: These can increase cholesterol secretion in the liver, making gallstone formation more likely and potentially reducing the effectiveness of Stener®. Clofibrate: This can counteract the effects of Stener® by encouraging gallstone formation. Always inform your doctor about all medications, supplements, or herbal products you are taking to avoid potential interactions.

A: Storage: Keep Stener® in a dry place at a temperature not exceeding 30°C. Protect it from light and moisture, and always store it out of reach of children. Overdose: Taking too much Stener® may cause diarrhea. If this happens, stop taking the medication and treat the symptoms (e.g., stay hydrated). In severe cases, contact your doctor immediately. Regular monitoring of liver function tests may also be necessary in the event of an overdose.
