Q & A: How Can I Obtain LDN?

In most countries LDN may be supplied only with a physician's prescription. Many countries permit sales of medication to foreign buyers without a prescription. This results in cross-border ordering of LDN mostly by people who cannot find a doctor to prescribe it. It is recommended to always have a knowledgeable physician oversee your medical care. Access our free global directory of LDN suppliers.
Since LDN is a non-commercialized treatment, doctors will not learn about it from the drug company sales representatives, as they learn about other treatments. Many doctors are afraid of prescribing off-label, or doing something that their colleagues don't do. The best chance of getting a doctor's cooperation is by showing him/her the scientific basis for your request. Referring them to (specifically to the pages showing all the studies that have been conducted to date) may convince a doctor that there is sufficient basis to experiment with LDN. If that does not work, then it may be best to work with a doctor already familiar with LDN therapy. A directory of such doctors is available on our site. If you are aware of any doctors who prescribe LDN and are not yet listed, please ask them or their office staff to register themselves with our website, or contact us with their information.

If you have looked on LDNscience’s free Find A Prescriber directory, and there is no LDN prescriber close enough to you, you may be able to find one in a few different ways:

Ask a prescriber on the LDN prescriber directory whether they can do a remote medical consultation with you (such as a video call). They will tell you whether remote consultation is an available service in your state and whether they personally provide this service. Call your local compounding pharmacy (see LDNscience’s free Where To Buy LDN directory) to ask which local health care providers prescribe low dose naltrexone.

Use social media to ask for recommendations of LDN-aware practitioners in your area. There are many Facebook® groups and Instagram profiles, for instance, dedicated to LDN use in specific conditions, and others in your area may have already walked this path before you.

If you find an LDN prescriber in your area that is not on LDNscience’s Find A Prescriber directory, please help the LDN community by encouraging them to register to be listed as LDN prescribers, so that others will have an easier time finding them in the future.

Naltrexone is a generic medication that is FDA approved at a 50 mg dose for treating opioid and alcohol abuse. Since the FDA has not formally approved the use of a lower dose, only compounding pharmacies are permitted to produce it at a lower dose if a physician prescribes that.
