At 3 1/2 years on gleevec 400mg. Have been <.oo1 for the past year. Last months test was .030 . Doc wants monthly pcr's for next 3 months is this overly aggressive or just conservative? Have BC insurance and saw threads about them not wanting to pay for PCR testing. Is .03 still mmr? The choice was mine yesterday to stay at 400mg doc would have upped dose or switched drugs. I have tolerated 400mg well. The heart warnings scare the crap out of me as I had cardiomyopathy and still take beta blockers for that condition. Any help would be appreciated.
