Hospital inpatient drug or alcohol rehabilitation is carried out in a hospital setting and is overseen 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 must be monitored 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 individuals who are addicted to opiates and wish to use this type of detox technique to avoid the severe withdrawal symptoms associated with heroin or other opiate withdrawal. This type of opiate detox is not treatment in itself however, and these individuals will require additional counseling and therapy to fully recover from addiction.
