Hospital inpatient drug rehabilitation is performed 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 client may encounter the onset of medically dangerous withdrawal symptoms, which is sometimes the case 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 opiate addicted individuals who 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 considered full rehabilitation and these individuals will need additional counseling and therapy to entirely recover from addiction.
