Risk calculators and risk factors for Psittacosis medical therapy

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

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. Since tetracyclines are contraindicated during pregnancy and infancy the preferred treatment is azithromycin.
