Does Avodart (Dutasteride) cause negative or harmful effects on the liver?

I've been taking Avodart (Dutasteride) twice a day for 6 and half months and now I'm planning to take it one pill every other day. I've been wondering if it causes any negative or harmful effects on the liver since the leaflet only stated that people who hav liver problems should be cautious in taking this drug, nothing was stated about it causing liver damage on healthy livers. I don't drink alcohol, soft drinks, eat junk food, fast foods. Just water and real food.
