Hospital inpatient substance abuse treatment is performed 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 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 individuals who are addicted to opiates and 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 treatment in itself however, and these individuals will require additional counseling and therapy to fully recover from addiction.
