The problem is that Subutex itself, being a partial opioid agonist, has addictive potential and prolonged use of which inevitably leads to addiction. Uncontrolled intake of Subutex causes typical opioid dependence, which in its turn requires a second detox.
The person may get rid of heroin addiction but become a subutex addictinstead. Characteristics of Subutex addiction are pretty much the the same of any other opioid addiction. Subutex is a long-acting opioid. It remains effective in the body for up to 48 hours.
Subutex Withdrawal symptoms are comparable to those from other opioids: muscle pain, headache, cold sweats, stomach pain, diarrhea, fever, insomnia, emotional disturbances such as depression and rapid mood swing. Intensity of subutex withdrawal usually is less than that of other opioids, but it lasts much longer (up to several weeks), making the process of detoxification excruciating, very annoying for the patient.
