Low Dose Naltrexone – LDN – for Cancer, Autoimmune Disorders, and More


Naltrexone is an FDA-approved prescription medication that is an opiate blocker. For example, it can be given at high doses (50 mg or more) to someone who has overdosed on heroin to reverse the effects of the opiate drug on the central nervous system.

Low dose Naltrexone, or LDN, is Naltrexone that has been compounded by a pharmacy into small doses, usually 3 mg – 4.5 mg, as a capsule or cream that is taken at night between 9:00 p.m. to midnight. When LDN is taken in this way, it can have dramatic effects on the immune system. Many conditions that involve the immune system have been shown to benefit from LDN. Please see www.lowdosenaltrexone.org for more information. Large-scale studies have not yet been done, but there are many anecdotal reports of treatment success.

When low doses of Naltrexone are taken at night, it causes a temporary blockade of our endorphin receptors, which then causes an endorphin rush several hours later. This increase in endorphin response is what is thought to cause the beneficial health effects of LDN.

Bay Area LDN – Low Dose Naltrexone

Endorphins are the body’s own natural opiates, and research is showing that these compounds are essential to the health and well-being of our immune system. The immune system is responsible for preventing infection of course, but is also involved in many other health issues, including allergies, cancers, and autoimmune disorders – such as Crohn’s, MS, Lupus, Autism, Parkinson’s, and much more.

Side-effects of LDN are rare, but the most common is trouble sleeping. Usually, this can be fixed by lowering the dose. LDN should not be used in patients who are currently taking opiates since it will interfere with their effectiveness. LDN is rarely used as a stand-alone treatment for immune disorders, but is often added to other treatments as an adjunctive therapy. Since it remarkably safe at these low doses, is relatively inexpensive, and has helped many patients, it is often “worth a try.” If you think that LDN might benefit you, please give us a call.
