Erlanger, a place with a 2019 estimated population of 19,246, is a home rule-class city in Kentucky. Although it is not one of the most populous cities, it is one that has consistently recorded an increase in population, which increases its chances of being home to a number of people suffering from opioid use disorder. The city has a total area of 22.1 km² of which 1.19% is water. Anyone around Erlanger who wants to treat opioid use disorder may visit any Erlanger methadone clinic for medication-assisted treatment. Although they are specialists in the dispensing of drugs to assist people who rely psychologically or physically on opioids, some methadone clinics in Kentucky offer additional services. Methadone makes the body calm, relieves pains, and reduces cravings. All these make it a very good opioid agonist. It has become an important drug so much that it has been included on the World Health Organization’s list of essential medications. Despite its effects, methadone is only available in certified methadone clinics. This is to avoid diversion into the illicit market and to make sure the side effects are rightly managed by the health provider. A short term methadone maintenance usually lasts about a year but some patients may need it for several years. It could go on indefinitely too.
