Hospital inpatient substance abuse rehabilitation is done 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 experience the onset of medically dangerous withdrawal symptoms, which is sometimes true when quitting alcohol as well as a category of prescription drugs known as benzodiazepines which should be supervised very carefully by medical professionals in case of any complications. Hospital inpatient treatment is also administered to individuals who choose to undergo medication assisted withdrawal, as is the case with opiate addicted individuals who wish to use this type of detoxification approach to avoid the harsh withdrawal symptoms associated with heroin or other opiate withdrawal. This type of opiate detox is not considered full rehabilitation and these people will need further counseling and therapy to completely recover from addiction.
