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 encounter the onset of life threatening withdrawal symptoms, which is sometimes true when quitting alcohol as well as a category of prescription drugs known as benzodiazepines which must be supervised very carefully by medical professionals in case of any complications. Hospital inpatient treatment is also delivered to individuals who desire a medication assisted withdrawal, as is the case with opiate addicted individuals who wish to use this type of detoxification technique to manage the harsh 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 entirely recover from addiction.
