I should double check the bilirubin numbers to be sure.
I wonder if Gilbert’s can cause buildup of fin overtime. If we had poor phase 2 detoxification (i.e. Gilbert’s), it could be that this caused finasteride to build up. From my research finasteride appears to slow down UGT1A4. Gilbert’s deals with UGT1A1 but I’m sure this forces compensation on the other glucuronidation enzymes. Also, finasteride impairs glutathione, so there goes that phase 2 enzyme. Finasteride is reduced after phase 1 to something that is like 20% potency of a 5-ar inhibitor, but if there is reduced phase 2 detoxification going on that would still be able to build up significantly over time.
