Low Dose Naltrexone (LDN) Compounding in Australia
Low Dose Naltrexone (LDN) Compounding in Australia: What Patients Need to Know
TL;DR
Low dose naltrexone (LDN) is prescribed at 1.5 to 4.5mg daily, but no commercial product exists at these doses. Standard naltrexone tablets are manufactured at 50mg for addiction medicine. LDN must be individually compounded by an accredited pharmacy from pharmaceutical grade naltrexone powder. This guide explains why LDN requires compounding, what dosage forms are available, how to order, and what quality standards to look for in an Australian compounding pharmacy.
Why Does LDN Require Compounding?
Direct Answer
Naltrexone is TGA approved in Australia at 50mg for alcohol and opioid dependence. No manufacturer produces naltrexone at the low doses (1.5 to 4.5mg) used for chronic pain, fatigue, and autoimmune conditions. Cutting a 50mg tablet into precise low doses is not clinically reliable. A compounding pharmacy prepares LDN individually from pharmaceutical grade raw ingredients, ensuring accurate dosing for each patient.
When your GP prescribes LDN, the prescription specifies a dose far below any commercially available product. A 50mg tablet cannot be accurately divided into 1.5mg, 3mg, or 4.5mg portions. The margin for error would be clinically unacceptable.
Compounding solves this. A compounding pharmacist weighs pharmaceutical grade naltrexone hydrochloride powder to the exact milligram specified on your prescription, then prepares it in a dosage form suited to your needs. Every batch is quality checked before dispensing.
What Dosage Forms Are Available for Compounded LDN?
Direct Answer
The most common form is an oral capsule containing the prescribed dose of naltrexone in a filler base. Liquid suspensions are also available for patients who cannot swallow capsules or who need very precise dose titration (e.g., starting at 0.5mg and increasing gradually). Some practitioners request transdermal creams, though oral capsules remain the standard.

How Is LDN Compounded at HolisticChem?
Your GP sends a valid prescription specifying the LDN dose (e.g., naltrexone 3mg capsules, quantity 30).
Our pharmacist reviews the prescription and confirms the formulation details. If clarification is needed, we contact the prescriber directly.
Pharmaceutical grade naltrexone hydrochloride powder is weighed to the exact dose using calibrated analytical balances.
The active ingredient is combined with a suitable filler (typically microcrystalline cellulose) and encapsulated under quality controlled conditions.
Every batch is checked against the prescription before dispensing. Your medication is dispatched via Australia Post Express or held for collection at our Bayswater pharmacy.
Most LDN prescriptions are prepared within 24 to 48 hours of receiving the valid prescription.
What Quality Standards Should You Look For?
Not all compounding pharmacies are equal. When choosing a pharmacy for LDN compounding, check for:
QCPP accreditation: Quality Care Pharmacy Program accreditation confirms the pharmacy meets national quality standards.
VPA compliance: Victorian Pharmacy Authority (or equivalent state authority) registration ensures regulatory compliance.
Pharmaceutical grade ingredients: The pharmacy should use TGA compliant, pharmaceutical grade raw materials, not food grade or imported unverified powders.
Pharmacist prepared: Every compound should be prepared and checked by a registered pharmacist, not unsupervised staff.
HolisticChem is QCPP accredited and VPA compliant. All compounds are prepared by our experienced pharmacist team under Keith Lee (AHPRA: PHA0001484970).
