Hydroxychloroquine Sulfate Description

Hydroxychloroquine is usually taken with food or milk to prevent stomach upset. It was approved for medical use in the United States in 1955. It regulates the activity of the immune system and modifies the underlying disease process, rather than simply treating the symptoms. Hydroxychloroquine sulfate works by reducing inflammation in people with autoimmune diseases.
