The doctor who prescribed LDN to me is a pulmonologist who was on the front lines in the early days of Covid. He works with other docs, prescribing LDN for many other illnesses as well, including supplementing for cancer therapies and gastrointestinal diseases. He has found it very beneficial and has been prescribing it for many years- prior to Covid. He believes you have to give it 6 months. I take 3mgs and it can be increased to 4.5 mgs if not seeing great results, which I’m considering . It’s used in long covid only for neurological symptoms.

I was seeing good results with head noises, and headaches, though fatigue still comes in
waves. I plan to stay on it indefinitely as it has helped some, can’t hurt, and is inexpensive.

I hope this is helpful.
