Ursodeoxycholic acid and Bile duct necrosis - a phase IV clinical study of FDA data

Summary:

Bile duct necrosis is reported as a side effect among people who take Ursodeoxycholic acid (ursodiol), especially for people who are female, 60+ old, and have Skin infection.

The phase IV clinical study analyzes which people have Bile duct necrosis when taking Ursodeoxycholic acid. It is created by eHealthMe based on reports of 7,467 people who have side effects when taking Ursodeoxycholic acid from the FDA, and is updated regularly.
