From what I understand, the dose depends on your weight/height. I take 75 mg. I don't notice any side effects except for sometimes loss of appetite. It has been fine on my liver even though I drink a lot of alcohol.
It's helped me but I still have some urgency first thing in the morning. I've been flaring for about a year and it hasn't worked to stop the bleeding.
