At MAT Recovery Centers, we understand the challenges of addiction and the importance of effective treatment options.
Naltrexone for cravings has emerged as a scientifically proven support for those struggling with substance use disorders.
This medication has shown remarkable success in reducing cravings and preventing relapse, particularly for alcohol and opioid addictions.
How Naltrexone Works in Addiction Treatment
The Science Behind Naltrexone
Naltrexone is thought to block endogenous opioids triggered by alcohol and has been found to reduce craving and help prevent relapse to heavy drinking. This medication blocks the brain’s opioid receptors, which reduces cravings and diminishes the pleasurable effects associated with alcohol and opioids.
When taken as prescribed, Naltrexone occupies the opioid receptors in the brain, preventing opioids or alcohol from activating these receptors. This blockade significantly reduces the euphoric effects typically experienced when using these substances, making it easier for individuals to resist cravings and maintain sobriety.
The FDA approved Naltrexone for the treatment of opioid dependence in 1984 and for alcohol use disorder in 1994. This approval was based on extensive clinical trials that demonstrated its efficacy in reducing cravings and preventing relapse.
Oral Naltrexone vs. Vivitrol: Choosing the Right Form
Naltrexone comes in two forms: oral tablets and an injectable version called Vivitrol. Each has its advantages, and the choice between them often depends on individual patient needs and preferences.
Oral Naltrexone requires daily intake, typically in a 50mg dose. This form offers flexibility and allows for quick adjustments if needed. However, it requires consistent daily adherence, which can challenge some patients.
Vivitrol, on the other hand, is a monthly injection of 380mg of Naltrexone. This extended-release formulation ensures continuous medication coverage for 30 days, eliminating the need for daily pills. However, long-acting injectable naltrexone (Vivitrol) does not decrease the likelihood of any relapse or relapse to heavy drinking compared with placebo.
Personalized Treatment Approaches
At MAT Recovery Centers, we work closely with each patient to determine the most suitable form of Naltrexone for their specific situation. Factors we consider include lifestyle, adherence history, and personal preferences. Our goal is to provide a treatment plan that not only works effectively but also fits seamlessly into our patients’ lives.
The choice between oral Naltrexone and Vivitrol often depends on individual circumstances. For example, professionals with demanding schedules might prefer the convenience of a monthly Vivitrol injection, while others might opt for the flexibility of daily oral medication.
Effectiveness in Different Substance Use Disorders
While Naltrexone is primarily known for its use in alcohol and opioid addiction treatment, research suggests it may also be effective for other substance use disorders. Some studies (albeit limited) have shown promising results in treating methamphetamine and cocaine addictions.
As we explore the effectiveness of Naltrexone in reducing cravings, it’s important to understand how this medication fits into a comprehensive treatment plan. Let’s examine the scientific studies supporting Naltrexone’s efficacy and compare its success rates with other medication-assisted treatments.
How Effective Is Naltrexone in Reducing Cravings?
Naltrexone has shown significant promise in reducing cravings and preventing relapse for individuals struggling with alcohol and opioid use disorders. Let’s explore the scientific evidence supporting Naltrexone’s effectiveness and how it compares to other treatment options.
Scientific Evidence Supporting Naltrexone
A study published in the Journal of the American Medical Association (JAMA) found that Naltrexone reduced the rate of heavy drinking by 17% compared to placebo-treated patients. This research demonstrates Naltrexone’s ability to decrease alcohol consumption.

For opioid addiction, a study in Norway showed that extended-release injectable Naltrexone (XR-NTX) was safe, effective, and tolerable in an opioid withdrawal and induction procedure. This research underscores the potential of Naltrexone in maintaining long-term sobriety for those recovering from opioid addiction.
Success Rates in Alcohol and Opioid Addiction Treatment
When it comes to alcohol use disorder, Naltrexone has demonstrated impressive success rates. A meta-analysis published in Addiction in 2014 found that Naltrexone reduced the risk of return to heavy drinking by 83% compared to placebo. This translates to a number needed to treat (NNT) of just 12, meaning that for every 12 people treated with Naltrexone, one additional person will benefit compared to placebo.
For opioid addiction, success rates are equally encouraging. A study in the American Journal of Psychiatry reported that 62% of participants receiving extended-release Naltrexone remained in treatment after 24 weeks (compared to only 32% of those receiving placebo). This highlights Naltrexone’s potential not only in reducing cravings but also in improving treatment retention.
Naltrexone vs. Other Medication-Assisted Treatments
While Naltrexone has proven highly effective, it’s essential to understand how it compares to other medication-assisted treatments (MAT). Methadone and buprenorphine are two commonly used medications for opioid addiction treatment.
A 2017 study in The Lancet compared extended-release Naltrexone to buprenorphine-naloxone for opioid use disorder. The study found that both medications were equally effective in maintaining abstinence once treatment was initiated. However, Naltrexone had a significant advantage in that it’s non-addictive and doesn’t carry the risk of misuse or diversion associated with opioid agonist treatments like methadone or buprenorphine.
For alcohol use disorder, Naltrexone has shown superior efficacy compared to other FDA-approved medications like acamprosate and disulfiram. A 2014 meta-analysis published in Addiction found that Naltrexone was more effective than acamprosate in reducing heavy drinking days and cravings.
Personalized Treatment Approaches
Medical professionals work closely with each client to determine the most appropriate medication and dosage, ensuring optimal results in reducing cravings and preventing relapse. This personalized approach takes into account individual factors such as medical history, severity of addiction, and lifestyle considerations.
The effectiveness of Naltrexone in reducing cravings is clear, but it’s important to understand how this medication fits into a comprehensive treatment plan. The next section will explore the implementation of Naltrexone alongside other therapeutic interventions for a holistic approach to addiction recovery.
Integrating Naltrexone into Your Recovery Plan
Synergy of Medication and Therapy
At MAT Recovery Centers, we implement a comprehensive approach to addiction treatment. Naltrexone serves as a powerful tool in the maintenance treatment of addiction, particularly when combined with psychosocial interventions. Cognitive Behavioral Therapy (CBT) and Motivational Enhancement Therapy (MET) have demonstrated particularly strong results when paired with Naltrexone. This combined approach addresses both the psychological and physiological aspects of addiction.
We customize our therapy programs to complement the effects of Naltrexone. For instance, CBT sessions focus on identifying and altering thought patterns that lead to substance use, while Naltrexone helps reduce physical urges.
Medical Supervision: An Essential Component
Proper medical supervision plays a critical role when using Naltrexone. Our medical team conducts thorough initial assessments, including liver function tests, as Naltrexone can affect liver enzymes in some patients. We then establish a monitoring schedule, typically involving regular check-ins and periodic blood tests.
Regular monitoring allows us to adjust dosages, address side effects promptly, and ensure the medication works effectively for each individual. This personalized approach has resulted in improved treatment adherence among our patients.
Managing Side Effects and Contraindications
While patients generally tolerate Naltrexone well, some may experience side effects. The most common include nausea, headache, and dizziness. We’ve developed a proactive management strategy:

It’s important to note that Naltrexone is contraindicated for individuals currently using opioids or in acute opioid withdrawal. We conduct thorough screenings to ensure patient safety. For those transitioning from opioid use, we have a specialized protocol to safely initiate Naltrexone treatment after a period of opioid abstinence.
