Low Dose Naltrexone Side Effects

What is Low Dose Naltrexone?

Low-dose Naltrexone is a medication and opioid blocker that is used to treat opioid addiction. It helps by reducing the side effects of how you feel when you use an opioid, which are used to treat moderate to severe pain relief and cause relaxation. It is an injectable substance that is usually used during treatment for alcohol or drug dependence.

Naltrexone at a low dose can be used in patients who have become dependent on opioid medicine and cannot stop taking it. It helps with preventing relapse and lessening the “need” or craving to use. It can also be used to treat alcoholism by reducing the urge you have to drink. It can help you to stop drinking altogether or allow you to drink less.

Is Naltrexone for pain? This drug is believed to be effective in treating chronic fatigue syndrome, chronic pain, fibromyalgia, multiple sclerosis, autoimmune or inflammatory diseases, and Crohn’s disease.  

How is Naltrexone Used?

To get the most benefit from low-dose Naltrexone it’s important to use it regularly. Typically, for the best outcome, it is given once a month or every 4 weeks and should only be given by a medical professional or doctor.

As part of treatment, there should be additional addiction rehab methods used in conjunction with Naltrexone including counseling, monitoring, and other alternative strategies to treat the substance abuse problem.

Dosage of Naltrexone?

The best way to determine the appropriate treatment dosage of low-dose Naltrexone is to visit your doctor or physician and to be prescribed the medication. This will allow you to find the proper dose for whatever your condition is and ensure you are safe during your treatment.

“Low-dose naltrexone (LDN), considered in a daily dose of 1 to 5 mg, has been shown to reduce glial inflammatory response by modulating Toll-like receptor 4 signaling in addition to systemically upregulating endogenous opioid signaling by a transient opioid-receptor blockade. Clinical reports of LDN have demonstrated possible benefits in diseases such as fibromyalgia, Crohn’s disease, multiple sclerosis, complex-regional pain syndrome, Hailey-Hailey disease, and cancer.” (Toljan and Vrooman, 2018).

How does Low Dose Naltrexone Work for Chronic Pain in Patients?

There is no definite answer to how LDN works and the mechanism of how it acts in the body. There has been some research that shows that it changes opioid receptors in the brain and blocks them which in turn can help with symptoms from fibromyalgia, fatigue, cancer, or other chronic pain-related illnesses.

Another study indicated that low-dose Naltrexone works as an anti-inflammatory in the peripheral and central nervous system and may limit the activity of specific cells in the brain called microglia. This helps to normalize the immune system, which helps patients with compromised immunity or other auto-immune illnesses.

Safety and Effectiveness

You should not begin taking low-dose Naltrexone if you are still suffering from opioid use disorder, have had a drink of alcohol, or have experienced withdrawal symptoms from your substance abuse. The effectiveness of the drug can be changed if it is not taken under the proper circumstances.
