Naltrexone FAQ

What is Naltrexone?

Naltrexone is a pure opiate antagonist because it attaches to the opiate receptors in the brain and blocks them 100%.

This means that if you try to use any kind of opiate drugs while being on Naltrexone, you will not feel the effects because all of the receptors are fully blocked. While Naltrexone is in the body, it is virtually impossible to relapse.

Naltrexone FAQ page will answer your questions about Naltrexone therapy.

When was Naltrexone developed?

Naltrexone has been available as an oral tablet since the late 1970s. However, Naltrexone tablet only works  24 to 48 hours and in practice, it has been found that most patients either forget or purposefully choose not to take their medicine.

As a result, in a short period of time ex heroin users go back to using heroin.

Higher success rates have been achieved when patients are forced to take their medicine, either by concerned family members, or by a court system such as probation or parole.

For this reason, we strongly recommend Naltrexone chip.

We believe that Naltrexone therapy should be given for 12 months. This gives ex opiate user a chance to have their brain’s rewarding system physically recover from the damage from the opiate drugs.

It also gives the patient an excellent chance to begin on the road to recovery.

Naltrexone FAQ

How does the Naltrexone protect from a drug addiction relapse?

Naltrexone (or ‘heroin blocker’) is a narcotic antagonist. It blocks the effects of heroin (and all other opiates like methadone, suboxone…) by blocking the opiate receptors within the brain.

Naltrexone works by binding to some of the drug receptors in your brain, preventing opiates from attaching. If opiates are taken, they simply will have no effect and therefore are a waste of money.

When you have Naltrexone chip under your skin, you are protected from relapse. You have more confidence and there is no craving like when being opiate free without Naltrexone.

When is the right time to start with Naltrexone therapy?

Immediately after the tests confirm that the body is 100% opiate free.

It means that there will not be any withdrawal reaction to a Naltrexone chip or Naltrexone injection. Everything will go smoothly.

How long should you be on Naltrexone therapy?

We believe strongly that patients should be on Naltrexone therapy for at least twelve months. This prevents them from relapsing back to narcotic use and gives the patients a chance for their brain rewarding system to recover and to start making changes in their lives.

Does Naltrexone chip stay under the skin after its working is over?

Yes, the biopolymers in the implant dissolve longer than Naltrexone. Therefore, the blocker stays under the skin a few months longer after the Naltrexone is released. That means that a new Naltrexone chip must be inserted before the old one is disappeared

What recommendations must be followed after the Naltrexone pellet insertion?

1. To visit a medical institution for a regular strangulation and surgical check ups
2. Keep your dressing clean and dry. Do NOT soak in a bath/tub. If you shower, you must cover the wound with plastic to keep dry.
3. Not to carry or lift heavy objects for at least 4 weeks after the implantation
4. To take the stitches out on time (normally on the 10th day)
5. To visit a doctor in the case there is slightest doubt about possible complications
