I think so - at least for heroin. Although a few years ago he ended up in the emergency room after his eyes turned a great shade of yellow - his tests did not indicate hepatitus at the time and he says he didn't take it seriously. He is still very interested in getting on Naltrexone - but is also a little worried that if his enzymes go down far enough so he can take it, that the drug itself will further harm his liver. I would really appreciate any nutrituional guidelines I can get. Again, as MDawson pointed out earlier in this forum - much cheaper than heroin.
Persistence always pays off.
I can tell you why doctors are concerned about high liver function tests when deciding whether or not to prescribe naltrexone. Your liver is composed of mostly liver cells. Basically, these cells provide many different functions unique to the liver. As a result, the liver cells contain specific enzymes and other proteins not found in other cells such as muscle, brain, and nerves. If your liver is exposed to any insult that results in damage to liver cells, the enzymes and proteins within the cells are released into the blood.
