There are actually no studies of accidental or intentional overdosage with ursodiol. One oral doses of ursodiol at 10 g/kg in mice and puppies, and five g/kg in rats weren't lethal. There might be other Unintended effects of ursodiol that aren't outlined here. Speak to your Health care supplier https://jaidencmswz.tinyblogging.com/about-urso-fofo-80943560
