Methadone 5mg is a prescription medication used to help manage chronic pain and to support treatment programs for opioid dependence. It works by acting on specific receptors in the nervous system, reducing pain signals and easing withdrawal symptoms in a controlled way. Because methadone has a long-lasting effect and carries risks such as sedation, respiratory depression, and dependence, it must be taken only with close medical supervision. A licensed healthcare professional determines the proper dose and monitors treatment to ensure safe, effective use.
