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 1.5 mg to 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.
