Naltrexone For Weight Loss – Overview

What is Naltrexone for Weight Loss? This is a concern for many individuals that are on prescribed medications to help them with their weight issues. Naltrexone is not intended for use as a means to permanently lose one’s weight, so if your physician orders Naltrexone to help with your weight issues, be sure to discuss it thoroughly with him or her before you take it.


First and foremost Naltrexone alone is not intended for permanent weight control and this alone is an off label usage of this medication. This medication is only intended for relief of constipation in patients with gastroenteritis and obesity. In other words, if you are taking Naltrexone for constipation, then it is not a way to stop your weight gain. Second, there are many better medications available for obesity, drugs which have already been approved by FDA as safe medications for obesity are not necessarily useful for a person who cannot take these medications. Third, for individuals with obesity, or who are obese and have refractory to traditional medications, there is a non prescription diet drug available called Orlistat. If you, or someone you know are already taking Orlistat for your high blood pressure, diabetes, and elevated triglycerides, then you may wish to discuss adding naltrexone to your treatment regimen.

Naltrexone can be added to either a low-dose pill or regular cream or tablet, or to a muscle relaxer. This will depend on the particular side effects and reactions associated with your current medications. A low dose will produce quicker results, but will also produce some side effects such as vomiting, drowsiness, nausea, diarrhea, dizziness, weakness, insomnia, fluid retention, dry mouth, joint pain, constipation, and muscle and joint pain. If you choose to use regular cream or tablet, then you must be sure to ask your physician if naltrexone should be added to the cream or tablet, especially if you are allergic to this ingredient. Be sure to also inform your physician if you are taking any other prescription or over the counter medications such as aspirin, seizure medication, beta blockers, antidepressants, MAOI medications, and antibiotics such as tetracycline, doxycycline, or any type of metabolic drug.

Naltrexone is sometimes recommended for patients who cannot tolerate the effects of the aforementioned medications. If you suffer from an addiction to caffeine or sugar, and you want to lose weight, then you may wish to consider bupropion or varenicline, another popular drug combination used to treat obesity. However, the Food and Drug Administration has warned that combining bupropion with other medications such as buprenorphine, can result in severe bupropion intoxication, resulting in coma, seizures, coma, or death.

Aside from these two medications, there are many other medications that help obese individuals lose excess weight. The two aforementioned medications plus a variety of others are currently being studied on the efficacy of their combination in assisting obese people to achieve long term weight loss. While these medications can help a person lose pounds, they may have some serious side effects that are currently being investigated. Some of these medications include bupropion and metformin, which can be administered alone; and Orlistat, a newly approved drug that needs to be taken along with an NSAID.

Because a higher than average number of people abuse alcohol, it has become a well known fact that a number of individuals suffer with serious side effects from drinking. If you drink alcohol on a regular basis or are planning to drink, then you should speak to your doctor before beginning a regimen of naltrexone to help you shed unwanted pounds. Some of these side effects include tremors, anxiety, nausea, and seizures. For this reason, it is generally not advised to begin taking naltrexone unless your doctor specifically advises you to do so.
