Why is LDN only available as a compounded medication?
Naltrexone is commercially available only in a 50 mg tablet. However, low-dose naltrexone (LDN) therapy is usually prescribed as 0.5mg-4.5 mg per day, adjusted to the correct dose depending on the patient’s response. Compounding pharmacies use naltrexone powder from FDA-approved facilities to formulate individualized dosing based on a prescription order. Prescribers should ensure that the compounding facility they choose is an accredited compounding lab.
