Hospital inpatient drug or alcohol rehabilitation is carried out in a hospital or similar 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 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 delivered to those 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 manage the harsh withdrawal symptoms associated with heroin or other opiate withdrawal. This type of opiate detox is not treatment in itself however, and these people will need further counseling and therapy to entirely recover from addiction.
