Hospital inpatient substance abuse rehabilitation is performed in a hospital setting and is supervised by doctors and other medical staff. Hospital inpatient treatment is sometimes necessary in the beginning stages of abstinence when the person may encounter the onset of life threatening withdrawal symptoms, which is sometimes the case when quitting alcohol as well as a category of prescription drugs known as benzodiazepines which must be monitored very carefully by medical professionals to minimize ant dangerous health complications. Hospital inpatient treatment is also administered to individuals who choose to undergo medication assisted withdrawal, as is the case with individuals who are addicted to opiates and wish to use this type of detoxification technique to manage the severe withdrawal symptoms associated with heroin or other opiate withdrawal. This type of opiate detox is not considered full rehabilitation and these individuals will need further counseling and therapy to entirely recover from addiction.
