Intervention and Treatment

Medication Assisted Treatment

Medication-assisted treatment, including opioid treatment programs, combines behavioral therapy and medications to treat substance use disorders. The Illinois Department of Human Services, Division of Alcoholism and Substance Abuse (IDHS/DASA) is the state's lead agency for addressing the profound personal, social and economic consequences of alcohol and other drug abuse through oversight of a network of community based alcohol and other drug treatment programs. The treatment system provides assessment, diagnosis, treatment, continuing care and recovery services to individuals with substance use disorders.

Naloxone is a medication used to prevent overdose by opioids by reversing the toxic effects of drugs such as heroin, morphine, and oxycodone. The medication can be given by intranasal spray, intramuscular (into the muscle), subcutaneous (under the skin), or intravenous injection. It is legal in Illinois for non-medical persons to administer Naloxone to another individual in order to prevent an opioid/heroin overdose from becoming fatal. Naloxone has been successfully prescribed and distributed to heroin users, their families and friends in several areas of the United States including Chicago. The IDHS/DASA has established and authorizes programs to distribute Naloxone through the Drug Overdose Prevention Program.
