HOW DOES IT WORK?

Opizone (naltrexone) works by blocking the opiate receptors in the brain, thereby preventing the euphoric effect you get from taking opiates (eg heroin, methadone) so there is no point using. In other words, Opizone helps to prevent relapse by acting as a ‘safety net’ to help you while you are adjusting to life without opiates.

Opiates are unable to bind to receptors due to Opizone blockade
and therefore have no effect

Important: Opizone only blocks the effects of opiates
You should never take opiates after taking Opizone. Although Opizone will normally block the effects completely, you should never try to 'test' this blockade as it could lead to overdose, which could be fatal.

As Opizone only blocks the effects of opiates you should be aware of the risks of starting or increasing the use of other substances.
