Hospital inpatient substance abuse rehabilitation is carried out 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 the case when quitting alcohol as well as a category of prescription drugs known as benzodiazepines which must be monitored 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 detoxification approach to avoid the harsh withdrawal symptoms associated with heroin or other opiate withdrawal. This type of opiate detoxification is not treatment in itself however, and these individuals will require further counseling and therapy to entirely recover from addiction.
