Methadone is a synthetic opioid medication primarily used to treat opioid use disorder and manage chronic pain. It works by binding to the same receptors in the brain as other opioids, helping to reduce withdrawal symptoms and cravings without producing the same intense high. Methadone is typically administered in a controlled setting, such as a methadone clinic, to ensure proper dosage and monitoring. It is important for patients to follow their healthcare provider's instructions closely, as misuse can lead to serious health risks, including overdose.
