Medication-assisted treatment is the use of medications, in combination with counseling and behavioral therapies, to provide a “whole-patient” approach to the treatment of substance use disorders. MAT is primarily used to treat opioids such as heroin or prescription pain relievers that contain opiates. The sole purpose of the medication in MAT is to normalize brain chemistry, block the euphoric effects of opioids, relieve physiological cravings, and normalize body functions without the adverse effects of the abused drug. Fortunately, the medications that MAT uses are all approved by the U.S. Food and Drug Administration (FDA), and each program is tailored to meet the specific needs of each client. Using these medications in conjunction with anxiety medications can have grave consequences; these medications include benzodiazepines like Xanax or Valium.
