... taking 2 6mg tablets a day for the last three week. In that time I have had 2 urine test. Neither of the tests showed any of the drug in my system. I am trying to understand why the drug doesn’t appear to be metabolizing in my system. If my body is not metabolizing the drug then I am concerned that it’s build up in my blood to toxic levels that could cause even more complications. Any input would be appreciated.

Thanks
