Multiple Choice

Doxycycline is the drug of choice for which diseases?

Doxycycline is the drug of choice for infections caused by intracellular bacteria such as rickettsiae, Chlamydia, and Borrelia. Its ability to penetrate tissues and enter cells lets it effectively inhibit protein synthesis in these organisms, making it the preferred first-line therapy for diseases like Rocky Mountain spotted fever and other rickettsial illnesses, ehrlichiosis and anaplasmosis, Q fever, early Lyme disease, and many chlamydial infections. The other antibiotics listed aren’t as reliably effective as first-line options for these particular pathogens. So, doxycycline is the best choice for these diseases.
