What to Expect Using Naltrexone for Alcohol Use

Breaking free from the grip of alcohol use isn’t just about willpower. It’s about giving your brain a fighting chance to heal. If you’ve been searching for a smarter, science-backed approach to drinking less or quitting altogether, Naltrexone could be the catalyst you’ve been missing. This medication doesn’t shame or shock you into sobriety. It subtly rewires the reward system that keeps you locked in the cycle. Curious about what that feels like? Whether you’re starting treatment or just exploring your options, understanding what to expect when using Naltrexone for alcohol use could be the first step toward reclaiming control. Let’s dive in.

What qualifies as alcohol use disorder

Alcohol use disorder isn’t just about drinking too much. It’s a chronic condition marked by an inability to control or stop drinking despite negative consequences. It can range from mild to severe and may include symptoms like a strong craving for alcohol, continued use despite problems at work or in relationships, and withdrawal symptoms when trying to cut back. Diagnosing AUD often involves both self-assessment and medical evaluation, using tools like the DSM-5 criteria or the AUDIT screening test.

Why is it so hard to drink less without help

Alcohol affects the brain’s reward system, releasing dopamine and creating a powerful sense of pleasure and relaxation. Over time, the brain becomes dependent on alcohol to trigger these feelings, making it difficult to stop without experiencing emotional and physical distress. Triggers, stress, and environmental cues make quitting even more complex. That’s why going it alone often leads to relapse because the struggle isn’t just psychological; it’s neurochemical.

What Is Naltrexone and How Does It Work

Naltrexone is an opioid antagonist. That means it blocks the brain’s opioid receptors, the same receptors activated by alcohol to produce euphoria. By doing so, Naltrexone diminishes the pleasurable effects of drinking. You may still drink, but it won’t feel the same, and over time, this blunted reward response can lead to reduced cravings and less frequent drinking. Think of it as turning down the volume on the urge to drink.

Forms of Naltrexone: Pills vs. Injections

Naltrexone is available in two primary forms: daily oral tablets and a monthly intramuscular injection.

• Oral Tablets (ReVia or generic)
  This is the most commonly prescribed form. Taken once a day, it offers flexibility and is easy to discontinue if needed. However, it requires consistency. Missing doses can weaken the effect and increase relapse risk.

• Extended-Release Injection (Vivitrol)
  Given once a month by a healthcare professional, this form ensures steady levels of the medication in your system. It’s ideal for those who struggle with daily pill adherence, but it comes with a higher price tag and the need for monthly clinic visits.

Both forms are effective, and the right one depends on lifestyle, access, and medical history.

Who Can Benefit from Naltrexone

Naltrexone is best suited for individuals who want to reduce or stop drinking but may not be ready or willing to commit to full abstinence. It’s especially helpful for people with moderate to severe AUD, those with repeated relapses, or anyone looking for a medication-assisted approach to reduce cravings. Unlike abstinence-only treatments, Naltrexone offers a flexible path toward recovery, which is key for people seeking a harm-reduction strategy.

When Naltrexone may not be recommended

Naltrexone isn’t for everyone. It should not be used by people currently dependent on opioids or those taking opioid pain medications, as it can trigger severe withdrawal. Individuals with acute hepatitis or significant liver dysfunction may also need alternative options due to the risk of liver toxicity. A full medical history and liver function tests are standard before starting Naltrexone to ensure safety and suitability.

Tracking your cravings and alcohol intake

Self-awareness is essential when using Naltrexone. Many people find that keeping a simple journal or using mobile apps to log cravings, drinking patterns, and emotional triggers helps identify progress and pinpoint setbacks. Tools like sunnyside apps, mood diaries, or even voice notes can offer insight into how your relationship with alcohol is shifting over time.

Why Naltrexone doesn’t require total abstinence

One of the most misunderstood aspects of Naltrexone is that it doesn’t require you to quit drinking entirely before starting. This is intentional. The medication is designed to be effective even if you continue to drink, because over time, it reduces the brain’s association between alcohol and pleasure. 

Combining Naltrexone with Therapy and Support

Medication alone isn’t a silver bullet. The best outcomes come when Naltrexone is paired with behavioral support. Cognitive Behavioral Therapy (CBT), motivational interviewing, and participation in peer support groups like the one Sunnyside offers reinforce progress. Therapy helps uncover the root causes of drinking behavior, while Naltrexone handles the physiological cravings together; they’re a potent combination.

Common Side Effects and How to Manage Them

Most people tolerate Naltrexone well, but like any medication, it can cause side effects. The most commonly reported include nausea, headaches, dizziness, and fatigue. These typically fade within a few days to a week. Less common but more serious side effects, like liver issues, should be monitored with regular lab tests. Staying hydrated, eating with your dose, and easing into the medication can help reduce initial discomfort.

Conclusion

Choosing to use Naltrexone for alcohol use is a courageous and informed step toward recovery. While it’s not a miracle cure, it’s a powerful tool that, when combined with support and commitment, can shift the way you relate to alcohol. Whether your goal is to drink less or quit altogether, Naltrexone can help make that path a little clearer and a lot more achievable.
