Hi. I am also on low does Naltrexone. It has helped me tremendously. I was getting it through a compounding pharmacy at a cost of about $900 a year. Finally figured out how to save almost all of that money by taking LDN oral solution - 1ml = 1 mg. So my 3mg dose is taken with a 3ml oral syringe. Annual cost is about $10 (no missing zeros!). It is available in a regular pharmacy and is fully covered by my insurance. Best, wishes to you.
