I'm interested in this also. Ive become intolerant to almost all meds.
I feel my liver takes too long to metabolize medications, I'm taking a liver clean cocktail, also hepato Thera forte, and just started taking SAM-e.
My liver enzymes are all in check now, but still having trouble with taking medications.
Examples for me are, I take a anti- estrogen med(I'm on testosterone therapy), before I had issues with my liver, I used to be able to take up to 1 mg a day of it, now if I even take as small an amount as .1 mg, it will drive my estrogen too low.
