Low Dose Naltrexone for Weight Loss: Dosage, Benefits, and Side Effects

Contrave, the FDA-approved medication for obesity, also contains bupropion, adding to the list of naltrexone side effects for weight loss. Naltrexone in isolation is not FDA approved as a weight loss medication, with the combination of naltrexone and bupropion as Contrave being a chronic weight management drug. All four studies demonstrated statistically significant and clinically meaningful weight loss following up to 52 weeks of treatment with naltrexone/bupropion compared with placebo. Naltrexone, originally developed as a medication to treat opioid addiction, has demonstrated potential as a weight loss aid due to its intriguing effects on the body. Factors such as individual health conditions, medication interactions, and potential side effects should be carefully evaluated and discussed with healthcare professionals before embarking on naltrexone treatment. We next examined the effects of NTX on HR recovery following a bout of FSw. Anesthesia was induced using 3% isoflurane and followed by a maintenance dose at 1–2% of ISO and adjusted to keep each mouse’s respiratory rate between 80 and 100 breaths per minute. Following acclimatization, mice were challenged with a 50-min bout of swimming/wading, an adequate time shown to induce opioid-mediated hyperphagia 5,17. By dampening the reward response to these foods, naltrexone can help individuals regain control over their eating habits. Naltrexone is classified as an opioid receptor antagonist, meaning it blocks the effects of opioids in the brain. This holistic approach has captivated the attention of individuals who have struggled with conventional weight loss methods or have faced challenges in controlling their food intake. Naltrexone has emerged as an intriguing candidate due to its unique properties and mechanisms of action, offering a new avenue for individuals striving to achieve their weight loss goals.

Naltrexone has been shown to reduce inflammation in various studies, which could, in turn, aid in weight loss. In the 1980s, naltrexone was also approved for the treatment of alcohol dependence, as it helps reduce cravings and the pleasurable effects of alcohol. This mechanism of action makes it an effective medication for treating opioid addiction and dependence. Before diving into the weight loss aspect, it’s essential to understand what naltrexone is and how it works. One reason for this is that many obese patients have health issues related to their weight including diabetes and hypertension. Unfortunately, Zepbound often has dose-dependent side effects. ​If they do not have side effects or have settled after at least 4 weeks on the 2.5 mg dose, it can be increased.

Patients with psychosis, dementia, andsecondary psychiatric diagnoses were excluded from these studies. Naltrexone appears to have extra-hepatic sites of drug metabolism and its major metabolite undergoesactive tubular secretion (see Metabolism). Although this is a hypothesis that would need to be validated in another study, if found to be true, the much briefer smoking protocol used in the present study could be used by primary care providers to address smoking cessation in weight concerned smokers. Even so, the same overall theoretical rationale was employed, in which dieting was explicitly discouraged, and this may have led to less weight gain for both study groups. Another related plausible explanation is the counseling protocol implemented in conjunction with the medications regimen. The most likely reason for the overall low weight gain in this sample relates to the study population (i.e., weight-concerned smokers).

• If the patients are not on an opiate pain medication, the combination drug can be used with the caveat that it will block antinociceptive effects of opiates if they are required in future.
• The inherent heterogeneity in study designs, populations, and outcome measures further complicates the process.
• In addition, the subgroup analysis showed that changes in weight loss and WC after receiving bupropion together with naltrexone were more compared to bupropion alone (Supplementary Table).

Moreover, 41.5% of NB32 + BMOD participants lost ≥10% of initial weight and 29.1% lost ≥15%, as compared to values of 20.2 and 10.9%, respectively, for participants who received placebo + BMOD (as determined by the modified-ITT analysis). In general, the remaining study drug discontinuations due to an AE in the first month were attributable to the same AEs shown in Table 4. Two serious AEs occurred in the NB32 + BMOD group that were considered possibly related to study drug. This amount of weight loss is clinically significant and can lead to improvements in health markers such as blood pressure, blood sugar levels, and cholesterol. Research on naltrexone and weight loss shows that weight loss outcomes tend to be moderate, but they can still be meaningful when combined with other lifestyle changes. Here’s what to know about setting achievable goals and understanding how naltrexone can support a gradual, sustainable weight loss journey. Naltrexone for weight loss is not a quick fix, and results can vary depending on individual factors such as metabolism, lifestyle habits, and adherence to a healthy diet and exercise regimen. While naltrexone can be a helpful tool in achieving weight loss, it’s essential to have realistic expectations regarding its effectiveness and timeline. The manufacturer’s dosing recommendations are based on data for naltrexone and bupropion individually (Table 1). The drug has not been evaluated in patients with renal or hepatic impairment. If this result is not attained within 12 weeks, then naltrexone/bupropion should be discontinued because it is unlikely that the patient will derive benefit from it. Dosing recommendations are based on the number of tablets, which contain 8 mg of naltrexone and 90 mg of bupropion. Initially, Contrave was rejected by the FDA in February 2011 because of the need for long-term clinical trials evaluating the cardiovascular effects of the drug.6 Contrave was finally approved in September 2014 after subsequent clinical trials demonstrated its safety and efficacy.7

The possibility of naltrexone binding at some other additional binding sites was also detected, but its minimum energy cluster showed the highest binding affinity for the main active site. The negative binding energy shows the spontaneous binding of naltrexone at the active site of SIRT1. The docked complex of naltrexone binds to the main active site of SIRT1 with low binding energy of −10.94 kcal. We performed a blind docking experiment to investigate the possibility of naltrexone interactions with SIRT1. Taken together, these results indicate that LDN specifically blocks hyperinsulin-stimulated nuclear localization of NF-κB p65, which is required for optimal p65-mediated transactivation potential of NF-κB and the LDN-stimulated anti-inflammatory phenotype depends on SIRT1. Naltrexone/bupropion has not been compared with other pharmacologic approaches. Both components are excreted in breast milk and the medication should not be taken by breastfeeding mothers.1 Because it may raise blood pressure and heart rate, it should not be used in patients with uncontrolled high blood pressure. Also, he showed that naltrexone-induced changes in pain were correlated with depression scores . Improvement in eating symptoms was observed between 4 and 24 weeks.

Always keep your healthcare provider informed about any changes in your health or medication regimen. If side effects persist or worsen, it's important to contact your healthcare provider immediately. An opioid-free interval of a minimum of 7 to 10 days is recommended forpatients previously dependent on short-acting opioids. Any attempt by a patient to overcome the antagonism by taking opioids is especially dangerousand may lead to life-threatening opioid intoxication or fatal overdose. This poses a potential risk to individualswho attempt, on their own, to overcome the blockade by administering large amounts of exogenousopioids. Naltrexone is a medication originally used to treat opioid and alcohol dependence. Naltrexone weight loss is gaining attention as a promising option for shedding pounds. CONTRAVE (naltrexone HCl and bupropion HCl) prescribing information. Contrave may increase the risk of low blood sugar in individuals with Type 2 diabetes who are using it for weight loss.

How Does Naltrexone Work in Weight Loss?

Taking naltrexone for weight loss can be effective, but timing matters. Consider how your body reacts to medications. Everyone’s body processes medications differently. The FDA says to take 32 mg of naltrexone and 360 mg of bupropion daily. They are found in Contrave, a drug approved for obesity. Naltrexone helps with weight loss by changing how we feel hunger. When paired with bupropion, it tackles weight gain from different angles. Using Naltrexone wisely can greatly improve weight loss efforts. However, it has the effect of making your weight loss “sticky.” This concept of the body set point is believed to be one of the reasons why only 1% of people can lose weight and maintain it. Your body controls your weight within a very specific range using hormones, metabolism, and hunger signals. Initially intended to treat alcoholism, naltrexone was developed as an opioid agonist. Conversely, a 30-year-old male reported minimal weight change despite consistent LDN use, highlighting the variability in individual responses. These improvements may be attributed to other lifestyle factors, placebo effect, or coincidental occurrences. We will examine specific case studies, analyze existing research, and address common misconceptions surrounding its use. With both forms, you’ll start at a low dose that increased over several months. That’s why Wegoy is started at a low dose that’s gradually increased over several months. But keep in mind that much smaller doses of semaglutide, sometimes called “microdoses,” haven’t been studied and may not provide the same results. If you can’t tolerate the recommended maintenance dose of Wegovy, your prescriber may have you stay on a lower dose if it’s working for you. Ask your healthcare professional how you should dispose of any medicine you do not use. The dose of this medicine will be different for different patients.

Therefore, we aim to monitor treatment compliance by also using riboflavin as a urinary tracer, which is strongly florescent under UV light. Although pill count is one of the most common methods to monitor treatment compliance, it lacks objectivity . Thus, we expect a similarly high dropout rate for the current study. Work with your health care provider to evaluate the potential benefits and risks of Alli or any other weight-loss drugs. No, Mysimba should be used as part of a comprehensive weight loss program that includes healthy eating habits and regular exercise. Different weight loss medications carry varying levels of thyroid-related precautions based on mechanism and preclinical data. This article reviews available data, compares risks across medications, and offers guidance for informed discussions with healthcare providers. Some studies proposed that bupropion causes significant weight gain 9, 10, some studies proposed that it cause significant weight loss 11, 12 and some stated no significant change in weight 13, 14. In conclusion, the addition of combination therapies like bupropion and naltrexone to lifestyle modifications including diet would cause significant weight loss. In addition, changes in weight loss and WC after receiving bupropion together with naltrexone were more compared to bupropion alone. The purpose of this search was to uncover controlled trials that examined the impact of bupropion, either as a standalone intervention or in combination with naltrexone, on weight loss outcomes. LDN is believed to modulate the immune system and may have anti-inflammatory properties, potentially influencing various health conditions, including weight management. Herein we investigated the functional expression of TRPV1 and TRPA1 in human keratinocytes and fibroblasts and assessed proinflammatory lipid mediator release upon their stimulation as well as sensory effects after topical application, combining in vitro and in vivo approaches. Certain TRP channels are affected by the typical genomic long-term effects of steroids but others are also targets for ... Transient receptor potential (TRP) channels are remarkable transmembrane protein complexes that are essential for the physiology of the tissues in which they are expressed. In both clinical trials, the incidence of constipation (15%–24%), dizziness (7%–14%), and dry mouth (8%) was higher with the study drug than with placebo. According to two published clinical trials,6,7 the most commonly reported adverse drug events (AEs) for naltrexone SR/bupropion SR were gastrointestinal in nature. Pharmacological treatments can be beneficial in regulating food intake and body weight in those individuals. Low dose naltrexone (LDN) involves using naltrexone at doses significantly lower than those used for opioid or alcohol dependence (typically around 4.5 mg per day). What are the common side effects of naltrexone for weight loss? A combination therapy of naltrexone and bupropion is effective and safer when compared with the use of naltrexone alone in the long run, when considering the management of weight issues. Participants were overweight (body mass index of 27 or greater), had type 2 diabetes, and had not been able to reach a blood sugar level below 7% with oral antidiabetic medications or diet and exercise alone. The most common side effects are mild and temporary, and may include headache, dizziness, and nausea. Naltrexone is generally considered safe and well-tolerated, with few side effects reported. Additionally, it can help to reduce stress and anxiety, which are common triggers for overeating. It works by blocking the opioid receptors in the brain, which in turn reduces cravings for food and increases feelings of fullness and satisfaction. This combination therapy has been shown to be more effective than using naltrexone alone. Naltrexone’s opioid receptor antagonism may affect the body’s natural opioid system, which plays a role in regulating appetite and food intake. Naltrexone is an opioid receptor antagonist, which means it binds to opioid receptors in the brain, blocking the effects of opioids and reducing cravings. Multiple dosages of naltrexone and naltrexone combined with bupropion are available from a compounding pharmacy.

Both common and serious naltrexone side effects need to be understood. This shows the need for treatments that fit each person’s unique situation for lasting health gains. This makes it a good choice for long-term weight management. In a situation requiring opioid analgesia, the amount of opioid required may be greater than usual, andthe resulting respiratory depression may be deeper and more prolonged. Safe use of naltrexone hydrochloride in ultra rapid opiate detoxification programs has not beenestablished (see ADVERSE REACTIONS). In the literature, endogenous opioids have been theorized tocontribute to a variety of conditions. Use of naltrexone hydrochloride should be discontinued in theevent of symptoms and/or signs of acute hepatitis. Althoughclinically significant liver dysfunction is not typically recognized as a manifestation of opioidwithdrawal, opioid withdrawal that is precipitated abruptly may lead to systemic sequelae, includingacute liver injury.

It's crucial to note that naltrexone should not be used by individuals who are currently using opioids or who have recently used opioids. Common side effects focus on gastrointestinal issues, sleep disturbances, and headache. Clinical trial data indicate higher rates of psychiatric events like anxiety compared to placebo in some pooled reviews. Naltrexone may contribute indirectly through its effects on stress responses. Prescribing information includes warnings about mood or behavior changes due to bupropion’s antidepressant-like properties. Most people adapt over time as the body settles into the regimen. Before initiating treatment, it is crucial for individuals to be opioid-free for at least 7-10 days to avoid precipitated withdrawal. Alternatively, an extended-release injectable form, administered as a 380 mg dose once every four weeks, is often prescribed for individuals who struggle with daily adherence to oral medication. In lower doses, Naltrexone is used for its anti-inflammatory and immune-modulating properties, offering benefits for patients with chronic pain and autoimmune diseases. Participants were included in the modified-ITT analysis population if they had ≥1 postbaseline measurement of weight while on study drug. Over the 56-week trial, 41.6% of participants in placebo + BMOD discontinued study drug, compared with 42.1% of NB32 + BMOD. In post hoc analyses, changes in SBP and DBP, from baseline to week 56, were plotted against percent change in body weight (during the same time) for each treatment group. Two sensitivity analyses were conducted to determine the effect of excluding (from the primary analysis of weight change) participants who did not provide a postbaseline measurement of weight on study drug. Participants who discontinued medication before the end of the study were encouraged to remain in the BMOD program and to return for scheduled study assessment visits at weeks 28 and 56 (for measurement of weight and waist circumference).
