Which antifungal medication is used for systemic lupus erythematosus?

Hydroxychloroquine is an antimalarial medication that is widely used in the treatment of systemic lupus erythematosus (SLE) due to its immunomodulatory properties. It helps manage and alleviate the symptoms of lupus by reducing inflammation and modulating the immune response, which is beneficial in preventing flares and managing chronic symptoms associated with the disease.

While acyclovir is an antiviral medication used primarily for herpes virus infections, mupirocin is a topical antibiotic for skin infections, and finasteride is used for benign prostatic hyperplasia and male pattern baldness, none of these options have a significant role in the treatment of systemic lupus erythematosus. Hydroxychloroquine stands out as the correct medication due to its specific indications in lupus management.
