Any medication for moderate Microalbuminuria other than tight control of HTN. DM with diet exercise like acetylcysteine Taurine?

Possibly. There appears to be some data supporting the use of acetylcysteine taurine for this purpose. You are already taking the usually recommended medication to prevent kidney damage in diabetes, i.e. telmisartan, an angiotensin receptor blocker. These drugs, along with ACE inhibitors, are the standard of care. Notable side effects of acetylcysteine are reported including rash. Review with your doc.
