Lauren Nichols, a 34-year-old logistics expert for the U.S. Department of Transportation in Boston, has been suffering from impaired thinking and focus, fatigue, seizures, headache and pain since her COVID-19 infection in the spring of 2020.
Last June, her doctor suggested low doses of naltrexone, a generic drug typically used to treat alcohol and opioid addiction. After more than two years of living in "a thick, foggy cloud," she said, "I can actually think clearly."
Unlike treatments aimed at addressing specific symptoms caused by COVID damage to organs, such as the lungs, low-dose naltrexone (LDN) may reverse some of the underlying pathology driving symptoms, they said.
Experiments by Dr. Sonya Marshall-Gradisnik of the National Centre for Neuroimmunology and Emerging Diseases in Australia suggest ME/CFS and long COVID symptoms arise from a significant reduction in function of natural killer cells in the immune system. In laboratory experiments, LDN may have helped restore their normal function, a theory that must still be confirmed. Others believe infections trigger immune cells in the central nervous system called microglia to produce cytokines, inflammatory molecules that cause fatigue and other symptoms associated with ME/CFS and long COVID. Younger believes naltrexone calms these hypersensitized immune cells.
