Hospital inpatient drug or alcohol rehabilitation is carried out in a hospital or similar setting and is supervised by doctors and other medical staff. Hospital inpatient treatment is sometimes necessary in the beginning stages of abstinence when the client 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 supervised very carefully by medical professionals to minimize ant dangerous health 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 harsh withdrawal symptoms associated with heroin or other opiate withdrawal. This type of opiate detoxification is not considered full rehabilitation and these people will need additional counseling and therapy to fully recover from addiction.
