How Low-Dose Naltrexone works

Low-dose naltrexone (LDN) is prescribed off-label and supervised by a licensed provider.

It is used at doses much lower than those prescribed for addiction treatment.

Your provider will review your full health history and medication list to determine whether LDN is appropriate for you.

Dispensed by a state board-licensed compounding pharmacy.

What low-dose naltrexone is

Naltrexone is an FDA-approved opioid antagonist. Low-dose use is a fraction of the approved dose and is off-label.

An approved medication, at a different dose

Naltrexone is FDA-approved at 50 mg for alcohol and opioid dependence. Low-dose use means a small fraction of that.

Low-dose use is off-label

FDA has not evaluated naltrexone at these doses for any of the uses it is compounded for.

An opioid antagonist

It blocks opioid receptors. Tell your provider about every medication you take, including anything for pain.

Compounded to strength

The low strengths are not commercially available, which is why the preparation is compounded.

Low-Dose Naltrexone questions

Is this the same naltrexone used for addiction?

Same medication, very different dose. Addiction treatment uses 50mg. LDN uses 1.5–4.5mg — about 10x less. The effects at this dose are completely different.

Will it affect my other medications?

It can interact with opioid-based medications. Your provider will review your full medication list before prescribing.

Important safety information

Last updated

These are compounded or off-label prescriptions used alongside a weight-management protocol where a provider determines they are appropriate.

Low-dose naltrexone is a strength that is not commercially manufactured — the approved product is 50mg — which is a legitimate reason to compound and is documented as such.

Naltrexone must not be taken with opioid medication and will precipitate withdrawal in anyone who is opioid-dependent.

Tell your provider about every medication you take.

Ondansetron can affect cardiac conduction.

Your provider reviews your history and other medications before prescribing it.

Compounded medication, prepared by a state-licensed pharmacy for individual patients. Compounded drugs are not FDA-approved, and the FDA does not review them for safety, effectiveness or quality. Prescribed only if your provider determines it is clinically appropriate for you.
