Naltrexone 50 mg has become a topic of interest for people looking to manage weight and curb cravings. While traditionally prescribed for opioid or alcohol dependence, many are now exploring its potential for weight loss.
With so many conflicting reviews online, it can be confusing to know whether Naltrexone 50 mg actually works for shedding pounds. Some users report noticeable weight loss and reduced appetite, while others see minimal results or experience side effects.
This article dives deep into Naltrexone 50 mg weight loss reviews, examining real user experiences, how the medication works, expected results, and potential risks.
By understanding the science behind Naltrexone, its dosage, and how it interacts with lifestyle factors like diet and exercise, you can make an informed decision.
If you’re curious about trying Naltrexone for weight loss or just want to see if it’s worth the hype, this guide provides a comprehensive overview.
What Is Naltrexone 50 Mg?
Naltrexone is a medication primarily known as an opioid antagonist, meaning it blocks the effects of opioids in the brain. It is traditionally prescribed to help people manage alcohol or opioid dependence by reducing cravings and preventing relapse. In recent years, Naltrexone has gained attention for its off-label use in weight loss, especially at a 50 mg daily dose.
At 50 mg, Naltrexone works by targeting the brain’s reward pathways, specifically affecting opioid receptors and dopamine release. This action can reduce cravings for high-calorie foods and help individuals feel less hungry, making it easier to stick to a diet and manage weight. While it is not FDA-approved as a standalone treatment for weight loss, Naltrexone is sometimes prescribed off-label by doctors who believe it can support appetite control and improve long-term weight management.
It’s important to note that Naltrexone 50 mg differs from low-dose Naltrexone (typically 4.5 mg), which is used for other purposes, such as inflammation or autoimmune support. The 50 mg dose is the standard strength most commonly discussed for weight-related benefits. While some users report moderate weight loss and improved eating habits, results vary widely depending on factors like diet, exercise, metabolism, and adherence to the regimen.
Is Naltrexone Approved for Weight Loss?
Naltrexone by itself is not officially approved by the FDA for weight loss. Its primary use is for treating opioid and alcohol dependence. However, Naltrexone has gained attention in the weight loss community due to its effect on appetite and cravings, especially when prescribed at the 50 mg dosage. While some healthcare providers may recommend it off-label for weight management, it is important to understand the regulatory distinction.
Contrave combines Naltrexone’s appetite-suppressing effects with Bupropion’s influence on the brain’s reward system and energy balance. This combination has been shown in clinical trials to support moderate weight loss over several months when combined with diet and exercise.
People taking Naltrexone 50 mg alone for weight loss are using it off-label, meaning the effectiveness and safety for this purpose have not been officially confirmed in large-scale studies. Doctors may prescribe it cautiously, monitoring side effects and progress closely. Users should be aware that results can vary, and taking Naltrexone without professional supervision can carry risks, especially for those with liver issues, opioid use history, or other medical conditions.
How Naltrexone 50 Mg Works for Weight Loss
Naltrexone 50 mg helps with weight loss primarily by affecting the brain’s reward and appetite pathways. It works as an opioid receptor antagonist, meaning it blocks certain receptors in the brain that are linked to cravings and pleasure. Normally, eating high-calorie foods triggers these receptors, releasing dopamine and creating a sense of reward. Naltrexone reduces this response, making food less “rewarding” and helping individuals control overeating.
In addition to appetite suppression, Naltrexone may also influence the hypothalamus, the part of the brain that regulates hunger and energy balance. By acting on this area, it can help reduce feelings of hunger, making it easier to stick to a calorie-controlled diet. This dual effect—reducing cravings and suppressing appetite—is why some users report moderate weight loss while taking Naltrexone 50 mg.
It’s important to note that Naltrexone alone is usually less effective than when combined with Bupropion (as in Contrave). Bupropion enhances energy expenditure and further reduces cravings, which is why the combination is FDA-approved for weight loss. Nevertheless, some users do see results with Naltrexone alone, especially when paired with consistent lifestyle changes like exercise and a balanced diet.
While Naltrexone 50 mg is not a magic solution, understanding how it works highlights why some people experience real weight loss. Its effectiveness depends on proper dosing, commitment to healthy habits, and careful monitoring for side effects.
Real Naltrexone 50 Mg Weight Loss Reviews
Many people turn to Naltrexone 50 mg for weight loss after reading mixed reviews online. Real user experiences highlight both the potential benefits and the limitations of this medication.
Some users report positive results, noting reduced appetite and cravings for sweets or high-calorie foods. These individuals often share that Naltrexone helped them stick to a healthier diet, leading to moderate weight loss of 5–15 pounds over a few months. Many also mention that pairing the medication with regular exercise enhanced their results. Success stories often emphasize the psychological benefit—feeling more in control of eating habits and less preoccupied with food.
On the other hand, some users experience minimal weight loss despite consistent use. This is often linked to lifestyle factors, metabolism, or individual response to the medication. Others report side effects such as nausea, headaches, or insomnia, which sometimes lead to discontinuation. A smaller group expresses frustration over off-label use, noting that the results were slower or less noticeable than expected.
Overall, user feedback suggests that Naltrexone 50 mg can work for weight loss, but results vary widely. Positive outcomes are generally tied to commitment to diet, exercise, and lifestyle changes, while negative experiences often stem from unrealistic expectations or side effects. Understanding both the successes and limitations helps set realistic expectations before considering this medication for weight management.
How Much Weight Can You Lose on Naltrexone 50 Mg?
One of the most common questions people ask is: “How much weight can I realistically lose on Naltrexone 50 mg?” The answer varies widely depending on factors such as diet, exercise, metabolism, and how strictly the medication is taken.
Based on real user reviews, many people experience moderate weight loss, often ranging between 5 to 15 pounds over 2–3 months. Some individuals report losing slightly more when Naltrexone is combined with consistent exercise and a calorie-controlled diet. However, it’s important to understand that Naltrexone alone is not a miracle solution—it works best as a tool to support healthier eating habits and curb cravings rather than as a standalone weight loss method.
Clinical data from the FDA-approved combination of Naltrexone and Bupropion (Contrave) shows that users can lose an average of 5–10% of their initial body weight over several months. While Naltrexone 50 mg alone may produce slightly less weight loss, real-world reviews suggest that even modest results can be motivating and help build sustainable lifestyle changes.
Factors that influence weight loss on Naltrexone 50 mg include:
- Diet quality: Lower-calorie, nutrient-rich meals improve results.
- Exercise habits: Regular physical activity enhances fat burning.
- Metabolism and genetics: Some individuals respond better than others.
- Consistency: Missing doses or irregular use reduces effectiveness.
How Long Does It Take to See Results?
When using Naltrexone 50 mg for weight loss, one of the most common concerns is the timeframe for noticeable results. Unfortunately, there’s no one-size-fits-all answer, as individual responses vary widely based on metabolism, lifestyle, and adherence to the medication.
Most users report seeing initial changes within 2–4 weeks. These early results often include reduced cravings for high-calorie foods, smaller portion sizes, and slightly less snacking between meals. However, actual weight loss may be slower, typically becoming more noticeable after 6–12 weeks of consistent use. Many users report moderate weight reduction of 5–10 pounds during this period, particularly when Naltrexone is paired with a balanced diet and regular exercise.
It’s important to remember that Naltrexone is not a rapid weight loss solution. Users who expect dramatic results in the first few weeks may feel discouraged. The medication works by supporting appetite control and healthier eating habits, which leads to gradual, sustainable weight loss rather than immediate shedding of pounds.
Consistency is key. Skipping doses or neglecting lifestyle changes can delay results. Tracking progress, such as weekly weigh-ins or keeping a food diary, can help users monitor improvements and stay motivated.
In summary, while some changes may be felt within a few weeks, significant and lasting weight loss generally takes 2–3 months or longer. Patience and commitment to healthy habits are essential to maximize the benefits of Naltrexone 50 mg.
Dosage & Usage Guidelines
For weight loss purposes, Naltrexone 50 mg is typically prescribed as a once-daily oral tablet. This dosage is considered standard for adults using Naltrexone off-label to help manage appetite and cravings. However, it is crucial to follow a doctor’s guidance, as individual needs and medical history can influence the appropriate dose.
Many healthcare providers start patients at a lower dose, such as 25 mg, to assess tolerance, and then gradually increase to 50 mg if well-tolerated. This step-up approach helps minimize common side effects, including nausea, headaches, or insomnia. Users should take Naltrexone at the same time each day, with or without food, as directed by their doctor.
Consistency is key to effectiveness. Skipping doses or irregular use may reduce appetite suppression and slow weight loss progress. Additionally, Naltrexone is not recommended for individuals currently using opioids, as it can precipitate withdrawal symptoms. Patients with liver disease or certain psychiatric conditions should also avoid use or proceed under strict medical supervision.
Lifestyle factors significantly enhance results. Combining Naltrexone 50 mg with a balanced diet, portion control, and regular exercise is essential for noticeable weight loss. Drinking plenty of water, avoiding alcohol, and maintaining healthy sleep patterns also support the medication’s effectiveness.
In summary, Naltrexone 50 mg can be effective for weight management when taken correctly, but medical supervision, adherence to dosage, and healthy lifestyle habits are critical for safe and successful results.
Side Effects and Risks of Naltrexone 50 Mg
While Naltrexone 50 mg can support weight loss and help control cravings, it is not without potential side effects and risks. Users should be aware of these before starting the medication and report any adverse reactions to their healthcare provider.
The most common side effects include nausea, headaches, dizziness, insomnia, and fatigue. Some users may experience dry mouth, constipation, or mild stomach upset. These symptoms are usually temporary and may decrease as the body adjusts to the medication. Starting with a lower dose and gradually increasing to 50 mg can help minimize these effects.
More serious risks, although less common, include liver toxicity. Individuals with pre-existing liver conditions should avoid Naltrexone or use it only under strict medical supervision. Naltrexone can also interact with other medications, particularly opioids, leading to withdrawal symptoms or reduced effectiveness of pain medications.
Certain populations should not use Naltrexone, including pregnant or breastfeeding women, individuals currently using opioids, and those with uncontrolled psychiatric conditions. Close monitoring is essential for people with depression, anxiety, or a history of seizures.
Despite these risks, many users tolerate Naltrexone 50 mg well, and side effects often subside after the first few weeks. Understanding these potential risks and following doctor-recommended dosing and monitoring guidelines ensures the safest and most effective experience when using Naltrexone for weight loss.
Pros and Cons Based on Reviews
When evaluating Naltrexone 50 mg for weight loss, it’s helpful to consider real user experiences to weigh the benefits and drawbacks. Reviews from forums, health blogs, and patient testimonials provide insight into what people can realistically expect.
Pros:

- Moderate weight loss: Users often achieve modest results, typically between 5–15 pounds over a few months, especially when combined with diet and exercise.
- Psychological support: Some individuals feel more in control of their eating habits and experience less stress around food choices.
- Convenience: A once-daily pill is easy to incorporate into a routine.
Cons:
- Side effects: Nausea, headaches, insomnia, and fatigue are common, especially in the first few weeks.
- Off-label use: Naltrexone alone is not FDA-approved for weight loss, meaning results can be inconsistent and medically unsupervised use carries risk.
- Slow results: Weight loss is gradual, which can frustrate users expecting rapid changes.
- Individual variability: Effectiveness varies widely due to metabolism, lifestyle, and adherence to healthy habits.
Overall, reviews suggest that Naltrexone 50 mg can be helpful for weight management, but it works best as a support tool alongside diet and exercise rather than a standalone solution. Understanding both the advantages and limitations allows users to make informed decisions and set realistic expectations before starting treatment.
Naltrexone vs Contrave for Weight Loss
When it comes to weight loss medications, it’s important to understand the difference between Naltrexone 50 mg alone and Contrave, the FDA-approved combination of Naltrexone and Bupropion. While both influence appetite and cravings, their effectiveness and approved usage differ significantly.
Naltrexone alone works by blocking opioid receptors in the brain, which reduces cravings for high-calorie foods and supports appetite control. Some users report moderate weight loss, typically between 5–15 pounds over several months, especially when combined with diet and exercise. However, because it is not FDA-approved for weight loss on its own, results can be inconsistent, and its use is considered off-label.
Contrave, on the other hand, combines Naltrexone with Bupropion, a medication that helps regulate mood and energy balance. This combination targets the brain’s reward system more comprehensively, leading to more significant weight loss outcomes. Clinical studies show that adults using Contrave, along with diet and exercise, can lose an average of 5–10% of their initial body weight over six months, often more than with Naltrexone alone.
Other differences include cost and accessibility. Contrave is typically more expensive and requires a prescription specifically for weight loss, whereas Naltrexone 50 mg may be more accessible but still requires medical supervision.
In summary, while Naltrexone 50 mg can support modest weight loss, Contrave tends to be more effective for significant, clinically proven results. The choice depends on individual goals, medical history, and consultation with a healthcare provider.
Who Should and Should Not Use Naltrexone
Understanding who can safely use Naltrexone 50 mg is essential for both effectiveness and safety. While it can help some individuals manage appetite and support weight loss, it is not suitable for everyone.

- Those with uncontrolled psychiatric conditions such as severe depression or seizure disorders.
- Individuals with a history of hypersensitivity or allergic reactions to Naltrexone.
Even for eligible users, it is crucial to follow a doctor’s guidance regarding dosage, monitoring, and lifestyle integration. Naltrexone works best as part of a comprehensive weight loss plan, and medical supervision ensures that potential risks are minimized while maximizing effectiveness.
