How Does Methadone Work?

Methadone binds with brain receptors activated by other opioids like heroin and morphine. It reduces cravings and withdrawal symptoms.

Opioid-dependent people who take methadone don’t experience the same kind of euphoria. One of methadone’s benefits is its long duration of action, allowing it to have a slow onset and prolonged effect.
