What is Naltrexone?

Naltrexone Molecule Structure

Naltrexone is an opiate receptor antagonist. The 50mg dose of Naltrexone was approved by the FDA for opioid and alcohol addiction in 1984. At much lower doses (0.5-9mg per day), it may provide relief to patients suffering from autoimmune diseases, chronic pain, mental health diseases, and inflammation.

Low Dose Naltrexone vs. Ultra-Low Dose Naltrexone:

Ultra-Low Dose Naltrexone (ULDN) is typically doses between one and ten micrograms (mcg). Low Dose Naltrexone (LDN) includes milligram (mg) doses from 0.5 mg – 4.5 mg.

Dosing Guidelines

It is critical to work with a provider or an accredited compounding pharmacy knowledgable in strategies that can help ensure success in using LDN. Optimal dosing is ultimately patient specific. Some patients find success very quickly, while others need to try a variety of dosing strategies while working closely with their provider and pharmacist.

To start out, we offer two different LDN capsule titration kits. Each kit increases the dose slowly by only 0.5 mg each week, until the patient’s therapeutic dose is reached. These titration kits range from either 0.5-4.5 mg or 1.5-4.5 mg of Naltrexone. Please consult with your health care provider to determine the best treatment plan for you.

In addition to capsules, LDN can also be compounded into a flavored oral suspension (almond, olive, and MCT oil bases) as well as a transdermal cream (various cream bases available).

Low Dose Naltrexone vs. Ultra-Low Dose Naltrexone:

Ultra-Low Dose Naltrexone (ULDN) is typically doses between one and ten micrograms (mcg). On the other hand, Low Dose Naltrexone (LDN) includes milligram (mg) doses from 0.5 mg – 4.5 mg.

These dosing guidelines are generalized for the purposes of clarity. Every patient is different, and we specialize in catering to each individuals’ needs when finding the right dose of Naltrexone. Contact our pharmacists for more information!
