Is ursofalk effective to take to dissolve a 1cm gallstone?

Not really: It depends on what you consider effective. These types of medications work very slowly, and the stones will return. Best treatment is surgical removal of the gallbladder entirely to remove the stones and prevent then from returning. Hope this helps!

Ursodiol is: sometimes effective in dissolving small cholesterol gallstones in a functioning gallbladder. But dissolution takes a while, many months to years, and side effects include liver toxicity. Given these limitations, cholecystectomy is usually advised for patients who have symptomatic gallstones and are acceptable surgical/anesthesia risk.

Not usually.: Ursodiol is used to dissolve gallstones only in certain circumstances, namely small stones, which are buoyant, which appear to be completely cholesterol stones. A 1 cm stone normally would not be attempted for dissolution therapy, unless the patient were at such a high risk for surgery that it could not be attempted. In your situation, it doesn't appear to be a good solution. Good luck.
