Plaquenil is a brand name for hydroxychloroquine, a medication primarily used to treat malaria, lupus, and rheumatoid arthritis. It's classified as an antimalarial and disease-modifying antirheumatic drug (DMARD). Imagine it as a multi-purpose tool ๐ ๏ธ for calming down an overactive immune system. It works by interfering with the immune system's activity, reducing inflammation and autoimmune responses. While once controversially touted as a COVID-19 treatment, its effectiveness for that purpose has not been proven.
