Low Dose Naltrexone (LDN)

Precise low-dose capsules — 0.5mg to 4.5mg and beyond — in the exact strengths prescribers need to titrate.

What is Low Dose Naltrexone?

Naltrexone is an FDA-approved medication originally developed for opioid and alcohol dependence, where it's used at 50mg. At much lower doses — typically between 0.5mg and 4.5mg — some physicians prescribe naltrexone off-label for indications other than its FDA-approved use.

Because these low strengths aren't manufactured in tablet form, LDN is compounded specifically to the doses each prescription calls for.

Why LDN Has to Be Compounded

The smallest manufactured naltrexone tablet is 50mg. Splitting or cutting those tablets can't reliably produce the sub-5mg doses LDN protocols call for — even 1/50th of a tablet is asking too much of a kitchen scale. Compounding lets us prepare capsules in exact milligram strengths, giving prescribers room to start low and titrate up on a schedule that fits the patient.

Our LDN Formulations

We prepare LDN in size #4 capsules — small enough to be comfortable for most patients. Strengths include 0.5mg, 1mg, 1.5mg, 3mg, and 4.5mg, with other strengths available when prescribed.

For patients with sensitivities, we can compound LDN with minimal hypoallergenic fillers — see our MCAS & Allergies page for more on dye-free and preservative-free preparations.

Prescription Required

LDN requires a prescription from a licensed healthcare provider. Because it's used off-label, not every physician prescribes it — if yours would like more information, our pharmacist can provide clinical resources. We also maintain relationships with integrative and functional medicine practitioners who prescribe LDN; visit our provider referrals page for more.
