I took it for a few years, No really side effect other than some GI upset the first few weeks and then an outbreak of acne from hell, I was 43 or so , that was BS.

Few months into it I had no problems are all. The highest dose I was able to tolerate was 900mgdaily. It does come with the need for routine blood work, yes, if your on it, increase your fluids, a lot.

I have since stopped taking it.
