Thank you for asking!  Hep c and use of heroine increase the staying in the system time for this Chat Doctor.  One reason is these medicines are metabolized in the liver and liver compromised is not efficient enough to process them in time. Next thing is that you might be on anti retrovirus, and they also increase their inside system time by blocking their metabolism further by inhibiting cytochrome enzymes. So all is explained. Hep c with a compromised liver and use of heroine is a resulting in its delay clearance. You can use naloxone to reverse the effects if any. Take care
