Naltrexone is an evidence-based medication approved for the treatment of both opioid use disorder (OUD) and alcohol use disorder (AUD). Unlike opioid agonist medications, naltrexone works by blocking opioid receptors, reducing the rewarding effects of opioids and alcohol, and helping support recovery. It is available in both oral and extended-release injectable forms and offers several advantages, including the absence of physical dependence and diversion potential. However, despite its effectiveness for many individuals, naltrexone has consistently demonstrated lower rates of treatment initiation and higher rates of discontinuation compared to other medications for opioid use disorder. The requirement for complete detoxification before starting treatment, challenges during early recovery, ongoing cravings, access barriers, and difficulties maintaining long-term engagement all contribute to these outcomes. Understanding the reasons behind these treatment challenges is essential for improving access, increasing retention, and supporting successful recovery outcomes.
Naltrexone: Low Rates of Initiation and High Rates of Discontinuation
Introduction
Naltrexone is an FDA-approved medication used to treat both opioid use disorder (OUD) and alcohol use disorder (AUD). It works by blocking opioid receptors in the brain, preventing opioids from producing euphoric effects and reducing the rewarding effects of alcohol. Naltrexone is available as a daily oral medication and as a long-acting monthly injection known as Vivitrol. Despite its effectiveness for some individuals, naltrexone has historically experienced lower treatment initiation rates and higher discontinuation rates compared to other medications for opioid use disorder, such as Buprenorphine and Methadone. Understanding these challenges is important for improving treatment engagement and long-term recovery outcomes.
Why Are Initiation Rates Low?
Requirement for Complete Detoxification
One of the biggest barriers to starting naltrexone is that individuals must be fully detoxified from opioids before treatment begins. Starting naltrexone too soon can trigger severe precipitated withdrawal symptoms.
This means patients often must:
- Stop opioid use completely
- Remain opioid-free for 7–10 days or longer
- Successfully complete withdrawal before receiving the medication
Many individuals struggle to complete this detoxification period.
Difficulty During Early Recovery
The period immediately after opioid cessation is often associated with:
- Intense cravings
- Withdrawal symptoms
- Anxiety
- Sleep disturbances
- Increased relapse risk
Many individuals return to opioid use before becoming eligible for naltrexone treatment.
Limited Access to Detoxification Services
Some communities have:
- Limited detoxification programs
- Long waitlists
- Transportation barriers
- Insurance challenges
Without access to medically supervised withdrawal services, initiating naltrexone becomes more difficult.
Why Are Discontinuation Rates High?
Reduced Motivation Over Time
As individuals begin feeling better, some may:
- Stop attending appointments
- Believe they no longer need medication
- Underestimate relapse risk
Reduced motivation can contribute to treatment discontinuation.
Craving Management Challenges
Unlike buprenorphine and methadone, naltrexone does not relieve opioid withdrawal symptoms or provide opioid agonist effects. Some individuals continue to experience:
- Cravings
- Emotional distress
- Recovery challenges
This may affect treatment retention.
Injection and Appointment Barriers
For extended-release injectable naltrexone:
- Monthly appointments are required
- Transportation issues may arise
- Scheduling conflicts can occur
- Missed doses increase relapse risk
Side Effects
Some patients discontinue treatment because of:
- Injection site reactions
- Nausea
- Fatigue
- Headaches
- Sleep disturbances
Although many side effects are manageable, they can affect adherence.
Impact on Recovery Outcomes
Low initiation and high discontinuation rates can lead to:
- Increased relapse risk
- Reduced treatment effectiveness
- Greater overdose vulnerability after discontinuation
- Increased healthcare utilization
- Interrupted recovery progress
The period following discontinuation can be particularly dangerous because opioid tolerance decreases, increasing overdose risk if opioid use resumes.
Strategies to Improve Initiation
Healthcare systems can:
- Expand access to detoxification services
- Improve care coordination
- Provide rapid treatment referrals
- Offer patient education about treatment options
- Reduce insurance and financial barriers
Patient Education
Patients may benefit from understanding:
- How naltrexone works
- Treatment expectations
- Potential side effects
- The importance of medication adherence
Strategies to Improve Retention
Strong Recovery Supports
Retention improves when individuals have:
- Counseling services

- Family involvement
- Mental health treatment
- Recovery support groups
Ongoing Follow-Up
Regular follow-up appointments help:
- Monitor progress
- Address concerns
- Manage side effects
- Reinforce recovery goals
Individualized Treatment Planning
Not every medication works equally well for every person. Shared decision-making can help match individuals with the treatment that best fits their needs and preferences.
Comparison With Other OUD Medications
Advantages of Naltrexone
- Non-addictive
- No physical dependence
- No diversion potential
- Monthly injectable option available
- Effective for both OUD and AUD
Challenges Compared With Other Medications
- Requires complete detoxification before starting
- Higher initiation barriers

Conclusion
Although naltrexone is an effective treatment option for opioid and alcohol use disorders, its clinical impact is often limited by low rates of treatment initiation and high rates of discontinuation. The requirement for complete opioid detoxification before starting treatment presents a major barrier, while ongoing challenges with cravings, motivation, side effects, and treatment engagement can contribute to early discontinuation. Improving access to detoxification services, strengthening recovery supports, enhancing patient education, and providing individualized treatment planning can help increase both initiation and retention rates. By addressing these barriers, healthcare providers and communities can improve treatment outcomes and support long-term recovery for individuals affected by substance use disorders.
