Block the Opioid Effect. Reduce Cravings. Create Time for Recovery.
Opioid addiction can create a relentless cycle of craving, use, temporary relief, withdrawal and returning to opioids. At DeBinge, opioid-dependent patients do not need to arrive having completed a separate opioid-free waiting window. The clinical team uses a medically supervised 4-to-5-day buprenorphine transition, with implantation typically around day 4 or 5 when clinically appropriate. Naltrexone then provides a fundamentally different form of medication support: it occupies opioid receptors rather than activating them.
Why Can Opioids Become So Difficult to Stop?
Heroin, fentanyl and prescription opioids act on opioid receptors involved in pain, reward and other essential body functions. Repeated exposure can produce tolerance and physical dependence, while craving and learned behavior can make returning to opioids difficult to resist even after someone genuinely wants to stop.
Tolerance
Over time, a person may need larger or more frequent doses to produce the effects previously achieved with less opioid. Higher exposure can increase the risk of serious harm.
Physical Dependence
When the body has adapted to regular opioid exposure, stopping can produce withdrawal symptoms. Avoiding withdrawal can itself become a powerful reason to continue using.
Craving & Learned Triggers
Stress, emotions, people, places and routines can become strongly associated with opioid use. Those triggers can remain even after the acute withdrawal period has ended.
Naltrexone Works Differently From an Opioid.
Naltrexone is an opioid receptor antagonist. This means it attaches to opioid receptors without producing the opioid effect that heroin, fentanyl, oxycodone or morphine produce.
Once a patient is appropriately detoxified and naltrexone is active, those receptors are occupied and opioids have substantially less ability to activate them.
Naltrexone itself is not an opioid and does not produce an opioid-type high.
Naltrexone Occupies the Receptor
The medication binds strongly to opioid receptors, creating a pharmacological blockade while sufficient medication remains active.
Opioids Produce Less Effect
Heroin and other opioids cannot activate occupied receptors normally, so their euphoric and sedating effects can be substantially reduced.
Cravings May Reduce
Naltrexone can reduce opioid craving. Response differs between individuals, so it should not be presented as guaranteeing that every urge disappears.
Recovery Gets More Space
A period of medication-supported stability can be used to focus on counseling, relationships, work, routines and rebuilding everyday life.
The Goal Is Not Simply to Stop the Drug for a Few Days. It Is to Interrupt the Cycle Long Enough to Build Something Different.
Someone can complete withdrawal and genuinely intend never to use opioids again — yet later encounter craving, stress, an old contact, a familiar environment or a difficult emotional situation.
Naltrexone adds a pharmacological barrier during that vulnerable period. While the medication is adequately active, taking an opioid does not produce its usual effect in the normal way.
That does not automatically repair the life surrounding the addiction. This is why DeBinge combines long-acting medication support with one year of professional counseling.
Create a Longer Window Between the Patient and the Opioid Reward.
With oral naltrexone, protection depends on continuing to take medication as prescribed. A sustained-release formulation is intended to release naltrexone gradually over an extended period, reducing reliance on making a new medication decision every morning.
During that period, the aim is not for the patient to simply wait for the medication to end. The aim is to use the time actively: addressing triggers, restoring relationships, improving physical health, rebuilding routines and developing a recovery plan that can continue beyond medication.
The Difference Is Also About Medication Adherence.
Naltrexone can be delivered in different forms. One of the practical challenges with daily medication is that continuing treatment requires another decision every day.
Medication That Must Be Taken Consistently
Oral naltrexone can provide opioid receptor blockade, but its effectiveness depends heavily on adherence.
If a patient stops taking the medication, the pharmacological protection does not continue indefinitely.
Medication Designed to Work in the Background
A sustained-release implant is designed to deliver naltrexone gradually rather than requiring daily tablets.
Exact duration and medication levels depend on the implant formulation and individual clinical circumstances. Your DeBinge doctor explains the specific implant used, expected duration and follow-up requirements.
Who Is the Naltrexone Implant For?
Because naltrexone rapidly blocks opioid receptors, administering it too soon after opioid use can trigger sudden and potentially severe precipitated withdrawal.
There is no requirement to arrive at DeBinge having already completed a separate opioid-free waiting window. For opioid-dependent patients, DeBinge uses a medically supervised 4-to-5-day buprenorphine transition, and the O’Neil Long-Acting Naltrexone Implant is typically inserted around day 4 or 5 when the treating team determines it is clinically appropriate. Timing still depends on what the patient has been taking, the duration of use and other clinical factors. Short-acting opioids and longer-acting medications such as methadone or buprenorphine require different preparation.
The treating medical team determines when it is safe to proceed. Patients should never attempt to accelerate this process themselves.
Naltrexone Is One Evidence-Based Option — Not the Only One.
Methadone, buprenorphine and naltrexone are established medication options for opioid use disorder. The best choice depends on the patient's circumstances, treatment history, preference and ability to complete the opioid-free period required for naltrexone.
Assessment. Detox Preparation. Implant. Long-Term Recovery Work.
Free Consultation
Tell us which opioids you use, how frequently you use them, previous treatment history and what happens when you attempt to stop.
Medical Assessment & Preparation
The clinical team reviews your health, medications, opioid dependence and the opioid-free period required before naltrexone can be considered.
Naltrexone Implant
Once medically cleared, the sustained-release implant is placed subcutaneously using an appropriate clinical procedure and anesthesia.
One Year of Counseling
The longer recovery period focuses on triggers, relationships, behavior, work, structure and creating a plan for life beyond opioid use.
Blockade Is Not a License to Test Opioids.
Naltrexone can block opioid effects while adequate levels are active, but this should never be described as making overdose impossible.
Patients and families need to understand how overdose risk changes during and after treatment.
What Naltrexone Can Add to Opioid Recovery
Opioid Receptor Blockade
Adequate naltrexone levels block opioid receptors and can substantially reduce the euphoric and sedative effects associated with opioids.
Reduced Opioid Craving
Naltrexone can reduce opioid cravings in suitable patients, although individual response varies.
No Opioid-Type High
Naltrexone is an antagonist rather than an opioid agonist and does not produce an opioid-type euphoric effect.
No Daily Tablet Routine
Sustained-release delivery reduces dependence on remembering or choosing to take an oral naltrexone tablet every day.
No Opioid Withdrawal When Naltrexone Stops
Naltrexone itself does not create opioid physical dependence. It does not need to be tapered for opioid withdrawal in the way an opioid agonist medication may require.
A Window for Behavioral Recovery
Medication support can create time to work on the psychological, social and practical factors that contributed to repeated opioid use.
Naltrexone Can Be Particularly Relevant for People Who Want an Opioid-Free Medication Approach.
The decision should be made with a qualified clinician. The patient must also be able to complete the required opioid-free period safely before naltrexone treatment begins.
Blocking the Drug Is Only One Part of Recovery. Building a Different Life Is the Bigger Part.
Opioid addiction can become connected with stress, trauma, pain, relationships, loneliness, boredom, identity and daily routine.
A medication cannot automatically change those things. What long-acting medication can potentially provide is a period of greater stability in which those issues can be addressed more consistently.
DeBinge includes one year of professional counseling so that the patient can work on triggers, coping strategies, relationships, routines and the practical decisions required for longer-term recovery.
Step Away From the Environment Where Opioid Use Became Normal.
People, places, routines and everyday pressures can become deeply connected with opioid use. Traveling to Nassau creates temporary physical distance from many of those triggers.
The Bahamas does not cure addiction. What the environment can offer is privacy, time and a different setting in which treatment and recovery become the immediate priority.
Once medically stable, some patients may also choose additional time in Nassau before returning home, using the period to establish healthier routines and prepare for the environment they will return to.
Opioids, Heroin & Naltrexone FAQ
Does naltrexone block heroin?
While sufficient naltrexone levels are active, it occupies opioid receptors and can substantially block the euphoric and sedative effects of heroin and other opioids. Patients must never test or attempt to overcome the blockade.
Does naltrexone reduce opioid cravings?
Yes. Naltrexone can reduce opioid craving, although the degree of benefit varies between individuals. Counseling and broader recovery support remain important.
Is naltrexone an opioid?
No. Naltrexone is an opioid receptor antagonist. It does not create an opioid-type high and does not produce opioid physical dependence.
Can I receive naltrexone immediately after using heroin?
No. A patient who remains physically dependent on opioids must complete an appropriate opioid-free interval first. Starting naltrexone too early can trigger severe precipitated withdrawal.
What if I take methadone or buprenorphine?
Tell the medical team before treatment. Transitioning from methadone or buprenorphine to naltrexone can require a longer opioid-free interval than short-acting opioids, and the timing must be medically supervised.
Does naltrexone make opioid overdose impossible?
No. It is dangerous to describe naltrexone as making overdose impossible. Attempting to overcome the blockade with large quantities of opioids can cause serious injury or death. Overdose risk can also be significant after treatment as opioid tolerance has fallen.
Is naltrexone better than buprenorphine or methadone?
There is no single medication that is best for everyone. Methadone, buprenorphine and naltrexone are established options for opioid use disorder. Treatment should reflect the patient's clinical needs, preferences and previous treatment experience.
Does the implant replace counseling?
No. Medication addresses one part of opioid use disorder. DeBinge includes one year of professional counseling because long-term recovery also requires attention to behavior, triggers, relationships, environment and daily life.
Evidence-Based Information About Naltrexone and Opioid Use Disorder
We encourage patients and families to understand how opioid use disorder medications work, what their benefits are and what safety considerations need to be understood.
Find Out Whether Long-Acting Naltrexone Could Be an Option for You.
Tell us what opioid you are using, when you last used, whether you take methadone or buprenorphine, what treatment you have tried before and what you want your recovery to look like.
This page provides general educational information and does not replace individual medical advice. Naltrexone must not be initiated in a person who remains physically dependent on opioids because it can precipitate severe withdrawal. Opioid overdose remains possible, particularly if someone attempts to overcome receptor blockade or returns to opioids after tolerance has fallen. Naltrexone itself is an established medication for opioid use disorder; regulatory status, evidence and duration differ between oral, injectable and individual sustained-release implant formulations. Treatment suitability must be determined by qualified healthcare professionals.
