Naltrexone (or ‘blocker’) is a narcotic antagonist; it blocks the effects of heroin (and all other opiates like methadone, subutex, substitol...) by blocking the opiate receptors within the brain. Naltrexone is extremely effective in blocking opiates. It works by binding to some of the drug receptors in one’s brain, preventing opiates from attaching. If opiates are taken, they simply will have no effect and therefore are a waste of money. Except for that, there is a risk of heroin overdoses along with an absence of having chemical pleasure (getting high).

Beginning with Naltrexone relapse prevention is only possible after a high quality detoxification. After the detox is finished, the patient is tested to opiate drugs otherwise, the withdrawal symptoms might begin.

Invented in the late 60-ees, Naltrexone is being implemented for more than 40 years in clinical practice. It is studied and tested thoroughly by FDA for the treatment of drugs and alcohol addictions.

Naltrexone in 50mg tablets or capsules for oral reception is issued under the trading name Revia, Nalorex, Antaxon and others. One capsule of Naltrexone blocks access to opiate receptors for not less than 24h.

Advantages of Naltrexone blocker:

  • Simple for implementation in outpatient treatment

Disadvantages of Naltrexone pills:

  • Daley reception is required in the period of few months without one single day missed
  • After a short while, a patient might start feeling strong enough to be able to stay clean without taking the Naltrexone pills. He or she might leave home without their stock of medication. He or she might forget taking the medicine. At the end, he or she might change their mind and refuse to take the pills. Soon after that, relapse happens in the majority of cases.
  • A person is forced to make a decision (consciously or subconsciously) on daily bases whether or not to take medicine, whether or not to take heroin instead. This constant internal struggle of motives depends on the mood swings. What will happen tomorrow?
  • For guaranteed regular reception of Naltrexone a long and intense control by relatives is required. As a result - mistrust, insults of the patient, new conflicts, suspicions. In fact, everyone in the family got tired of struggling and quarrels during the long period of illness.
