Hospital inpatient drug or alcohol rehabilitation is performed in a hospital or similar setting and is supervised 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 true when quitting alcohol as well as a category of prescription drugs known as benzodiazepines which should be monitored very carefully by medical professionals to minimize ant dangerous health complications. Hospital inpatient treatment is also administered to those who choose to undergo medication assisted withdrawal, as is the case with opiate addicted individuals who wish to use this type of detoxification technique to manage the severe withdrawal symptoms associated with heroin or other opiate withdrawal. This type of opiate detoxification is not considered full rehabilitation and these people will require additional counseling and therapy to fully recover from addiction.
