While both naltrexone and Suboxone reduce opioid cravings, they do so in very different ways.
Suboxone is an opiate blocker, but it also contains an opiate (buprenorphine) to help detox individuals addicted to heroin and other opioids.
As an opiate, there are addiction, withdrawal, and euphoria concerns associated with Suboxone.
Naltrexone, on the other hand, is solely an opiate blocker, so it is not addictive, does not cause a high, and has little to no withdrawal symptoms.
As such, naltrexone is prescribed to individuals who are no longer after the “high” and want to focus on recovery.
Both medications can be prescribed by a doctor and monitored in a doctor’s office.
