Hospital inpatient substance abuse rehabilitation is done 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 must be monitored very carefully by medical professionals to minimize ant dangerous health complications. Hospital inpatient treatment is also delivered to individuals 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 avoid 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 further counseling and therapy to entirely recover from addiction.
