Some patients, with the guidance of a medical provider, intentionally take naltrexone only one to two hours before they know they will have a drink (sometimes referred to as “The Sinclair Method”). Whether your goal is to remain abstinent from alcohol or just naltrexone side effects manage your relationship with alcohol, it’s important to follow your medical provider’s guidance should you be prescribed the medication. Side effects are generally mild and often diminish over time (Exhibit 4-2), although less common reactions and some potentially serious reactions have been reported (Exhibit 4-3). However, in clinical studies side effects were rarely cited by patients as reasons for discontinuing treatment with naltrexone. Naltrexone’s duration of action (which is greater than 24 hours) allows a variety of flexible dosing schedules. Naltrexone may afford people with AUDs a measure of control that can prevent a slip from becoming a full-blown relapse.
- It’s designed to be used after you’re clear of opioids in your system and are past the withdrawal phase of recovery.
- He earned an MD degree in 2008 and later completed Harvard Medical School’s lifestyle medicine training in 2012, before obtaining a PhD in holistic health and an ScD in sports nutrition.
- This formulation provided a new option for patients struggling with daily medication adherence, as it only needed to be administered once a month.
- As with this full guide, the following is not medical advice, but rather guidance from our research and experience.
How does naltrexone compare with naloxone?
Research has shown that naltrexone decreases reactivity to drug-conditioned cues and decreases craving. Extended-release naltrexone should be part of a comprehensive management program that includes psychosocial support. First developed 60 years ago, naltrexone is a once-daily pill (or monthly injection) that is approved by the FDA to treat both alcohol use disorders (AUDs) and opioid use disorders (OUDs). It works by targeting the brain’s opioid system, a key part of the reward pathway that makes alcohol and opioids feel rewarding. When someone drinks or uses drugs, the brain releases chemicals like dopamine, which produce feelings of pleasure and reduce both physical and emotional discomfort. Naltrexone blocks these effects, dulling the sense of reward that comes from substance use.
- Medication for AUD, like naltrexone, can be an effective treatment, as well as counseling, therapy, and mutual support groups.
- Researchers found that Naltrexone effectively blocked the effects of opioids and helped reduce cravings, making it a promising option for preventing relapse after detoxification.
- By precisely targeting the opioid system, Naltrexone offers a powerful tool in the fight against addiction.
- Other research has found naltrexone leads to fewer thoughts about alcohol, less interest in daily drinking and heavy drinking, and reduced appeal of alcohol.

He received his undergraduate degree from the University of Michigan-Ann Arbor and M.D. By boosting endorphin production, LDN may contribute to improved emotional resilience, mental clarity, and restorative sleep. Many users describe feeling more balanced, energized, and grounded within weeks of starting. If you’re exploring options for sustained energy, better sleep, or long-term well-being, LDN is a gentle, research-backed option worth learning about.

Naltrexone For Alcohol Use Disorder

It’s also worth noting that naltrexone can interact with other medications, particularly opioids. If you’re taking any prescription painkillers, be sure to discuss this with your doctor before starting naltrexone. So you may have a raised risk of liver problems if you drink alcohol while taking naltrexone. You should avoid drinking alcohol during treatment with naltrexone. Opioids are powerful, addictive drugs that have high risks of misuse and dependence. The Food and Drug Administration (FDA) approves prescription drugs such as naltrexone to treat certain conditions.
We’re not designed to change our habits overnight, but research shows that focusing on small, tiny, manageable changes can lead to big changes. Combining something like 10 minutes of movement every day, or adding a serving of veggies to every dinner, can become a part of an overall healthier lifestyle. It might sound small, but that’s your best bet for long-term results. The easier the health habit is, the more likely you are to stick with it. Monitoring your behavior makes you more likely to achieve your goals. Sunnyside uses the latest science-backed strategies to help you track your drinks and stay motivated.

The injectable form improved treatment adherence and ensured consistent medication levels, reducing the risk of relapse. In 1984, the FDA approved Naltrexone for the treatment of opioid dependence, marking a significant milestone in addiction medicine. This approval came after substantial evidence demonstrated its effectiveness in preventing relapse for individuals who had already undergone detoxification. Building on the success of Naloxone, researchers at Endo Laboratories (now part of DuPont) aimed to develop a longer-acting opioid antagonist suitable for ongoing addiction treatment. This led to the synthesis of Naltrexone in 1969, which had a longer half-life and could provide extended effects, making it more suitable for treating substance use disorders.
Naltrexone Interactions: What You Should Know Before Starting Treatment
A 2010 study specifically on non-abstainers showed promising results. A total of 952 alcohol-dependent men and women participated in a 16-week trial. People who drank more regularly seemed to benefit most from naltrexone, supporting The Sinclair Method theory. However, this may mostly apply to a small subgroup of very regular drinkers to reduce heavy drinking days. This method was developed by neuroscientist Dr. David Sinclair https://khatiz.online/7-rappers-that-struggle-with-addiction/ back in the 1990s.
As we continue to unravel the intricacies of Naltrexone’s action, new possibilities emerge for addiction treatment and other medical fields. The journey of discovery with Naltrexone is far from over, with exciting developments on the horizon in addiction medicine and neuropsychopharmacology. The mechanism of action of Naltrexone is a testament to the complexity of human biology and the advancements in medical science.
Animal studies conducted in the 1980s established that naltrexone decreased alcohol consumption through its action at the opiate receptors. Naltrexone is an FDA-approved medication used to treat alcohol use disorder (AUD). When you drink alcohol, it releases endorphins that activate opioid receptors in your brain. This process creates feelings of pleasure and relaxation, reinforcing the urge to drink. Used to treat both opioid use disorder and alcohol use disorder, naltrexone is prescribed in addition to therapy for addiction recovery. Naltrexone is available as a pill for alcohol use disorder or as an extended-release intramuscular injectable for either opioid or alcohol use disorder.
Oral Naltrexone vs. Injectable Naltrexone: Which is Best?
That’s because it binds to your opioid receptors, stopping them from activating and releasing the chemicals. That means naltrexone dampens the feel-good effects of alcohol, so you start craving alcohol less. Your reward system starts to learn that alcohol doesn’t actually offer any benefits, and instead, you may notice its negative effects. Scientists were looking for ways to block opioid receptors in the brain so that the drug didn’t have such an intense impact. Once they realized it also worked on alcohol, the narrative from Alcohol Use Disorder as a “personal failure” to a chemical issue could start to shift.
Naltrexone can also be administered via an implant, an unregistered form of naltrexone treatment which is yet to be supported by high quality evidence. It can be accessed in Australia under the TGA Special Access Scheme. Should you wish to stop naltrexone, call your healthcare provider. Do not take naltrexone unless it has been prescribed to you by a healthcare provider.
