Acute inpatient detoxification is the highest level of intensity available. Patients admitted at this level of care are severely addicted to drugs or alcohol and have recently, usually within the last 24 hours, used the substance to which they are addicted. They are commonly still under the influence of the substance upon intake to the facility. It is also common for patients to begin experiencing severe withdraw symptoms prior to intake. A medically managed program is the safest approach. Patients in this first phase of recovery need access to the full continuum of behavioral health care, and often need 24 hour monitoring to properly address acute withdrawal symptoms as well as to administer prescribed medications in order to detoxify the body of the substance.
