Many people wonder if they can buy hydroxychloroquine online as an antibiotic, but the truth is that hydroxychloroquine is not an antibiotic. Instead, it is an antimalarial and disease-modifying anti-rheumatic drug (DMARD). It works by interfering with parasite growth in malaria and by calming the immune system in autoimmune conditions such as lupus and rheumatoid arthritis. Unlike antibiotics, which fight bacterial infections, hydroxychloroquine does not kill bacteria. Understanding this difference is crucial to avoid misuse. Always consult a healthcare professional before use, and only purchase from trusted online pharmacies for safe and effective treatment.
