Hydroxychloroquine became a hot topic during the COVID-19 pandemic, with Dr. Peter McCullough emerging as one of its strongest supporters. After using the drug himself during his battle with COVID-19, Dr. McCullough firmly believes it played a key role in his recovery. “Hydroxychloroquine far and away made the biggest difference,” McCullough says. “It is not a cure alone, but it makes a giant difference.” Based on his experiences with COVID-19, Dr. McCullough and his colleagues developed a protocol, published in the American Journal of Medicine, that emphasizes starting treatment early to prevent severe illness. This protocol includes hydroxychloroquine, zinc, vitamins, and other supportive therapies. The goal is to stop the virus before it can cause life-threatening damage.
