welcome to HCM!
Hepatic side effects are very rare for Flomax
,only isolated instances of elevated liver
function tests have been associated with the use of Flomax.
especially when taken alone and not in combination therapy is hepatotoxic and may cause rise in liver function ,your AST, ALT and bilirubin
may have taken a jump due to this medicine.The level will return to normal once you stop this.
hope this will help!
