Cedar Rapids, the county seat of Linn County, is the second-largest city in the U.S. state of Iowa. Its 2018 population estimated at 133,174 means the city could be home to a number of people experiencing opioid dependency. Such people may contact a medication-assisted treatment practitioner at any Cedar Rapids methadone clinic. Cedar Rapids has a total area of 186.7 km² and a number of methadone clinics. There are different methods of overcoming opioid dependency, but methadone is one of the three approved drugs for medically treated opioid dependency. Methadone has been used by medication-assisted treatment experts over the years to correct the physical and psychological effects of opioids. Its level of effectiveness has given it a place on the World Health Organization’s list of essential medications. Ideally, doses of methadone are only available at methadone clinics certified by the Substance Abuse and Mental Health Services Administration to run an opioid treatment program. Doses are available in various forms including powder, diskettes, and liquid. Before doses are given to program enrollee, the health practitioner considers their full health history and informs the patients about the possible side effects. All methadone clinics in Iowa are required to register with the Drug Enforcement Administration before the dispensing of medication.
