Hospital inpatient substance abuse rehabilitation is carried out in a hospital setting and is supervised by doctors and other medical staff. Hospital inpatient treatment is often 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 should be monitored very carefully by medical professionals to minimize ant dangerous health complications. Hospital inpatient treatment is also delivered 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 approach to avoid the severe withdrawal symptoms associated with heroin or other opiate withdrawal. This type of opiate detoxification is not considered full rehabilitation and these people will require further counseling and therapy to completely recover from addiction.
