Opioid Dependence

Opioid dependence develops when the brain adapts to repeated exposure to opioids, including heroin, opioid painkillers, or synthetic opioids, and can no longer regulate mood, pain, and motivation without them. It is recognised as a chronic medical condition, not a failure of willpower. Stopping abruptly triggers withdrawal: sweating, cramps, agitation, and intense cravings that make unassisted recovery extremely difficult.

Blocking cravings to support recovery

Once a person has cleared opioids from their system, the main risk is relapse. Naltrexone works by blocking opioid receptors entirely, so that taking an opioid produces no reward. This makes it a useful maintenance tool for motivated individuals who have already completed detoxification. It is used alongside counselling and peer support rather than as a stand-alone fix. Full addiction recovery programmes combining medication with behavioural therapy consistently show better outcomes than either approach alone.
