Overview
Psittacosis is treated with tetracyclines. Remission of symptoms usually is evident within 48-72 hours. However, relapse can occur, and treatment must continue for at least 10-14 days after fever abates. For pregnant patients or infants, the preferred treatment is azithromycin because tetracyclines are contraindicated.
