Treatment Summary
Hydroxychloroquine is a medication used to treat malaria, rheumatoid arthritis, lupus, and other conditions. It was developed during World War II as a less toxic alternative to chloroquine and was approved by the FDA in 1955. The FDA previously authorized emergency use of hydroxychloroquine for the treatment of COVID-19, but revoked this authorization on June 15, 2020 due to safety concerns. A recent study found that hydroxychloroquine may be associated with increased risk of fatality when used to treat COVID-19.

How Hydroxychloroquine Sulfate Affects Patients
Hydroxychloroquine affects the way cells in the body work, and can help to reduce autoimmune diseases. It also stops plasmodia, a type of parasite, from getting energy from hemoglobin. Hydroxychloroquine is usually taken on a weekly basis, but it can cause low blood sugar levels in those with diabetes, so they should monitor their blood sugar levels closely. It is not effective in areas where malaria resistance to chloroquine has been reported.
How Hydroxychloroquine Sulfate works in the body
Hydroxychloroquine works by raising the pH of lysosomes inside the malaria parasite, preventing it from digesting hemoglobin. It can also stop a parasitic enzyme from working, trapping a toxic product in the cell. In human cells, hydroxychloroquine raises the pH of organelles, which reduces the inflammatory response and prevents the presentation of antigens to autoimmune T cells. It can also prevent viruses like SARS-CoV and SARS-CoV-2 from entering cells by inhibiting glycosylation of ACE2, the receptor they use to enter.

Is hydroxychloroquine sulphate a steroid?
"Federal government websites often end in . gov or . mil. Before sharing sensitive information, make sure you're on a federal government site
Hydroxychloroquine may help to reduce the need for steroids in people with immune thrombocytopenia, according to a review of the medical literature. The review looked at data from several studies involving hydroxychloroquine as a treatment for immune thrombocytopenia, a condition in which the body's immune system attacks and destroys platelets. Hydroxychloroquine is typically used in combination with other immunosuppressive drugs, and the review found that it may help to reduce the dosage or duration of steroid therapy in some cases. The review also found that hydroxychloroquine was generally well-tolerated, with few serious side effects."
