OBJECTIVE To provide ideas and reference for the anti-infection treatment and pharmaceutical care for severe pneumonia caused by Chlamydia psittaci. METHODS Clinical pharmacists participated in the whole process of the treatment for a patient with C. psittaci-induced severe pneumonia. According to the patient’s medical history， clinical symptoms and test results， clinical pharmacists assisted the physician to dynamically adjust the anti-infective scheme； for C. psittaci infection， the patient was treated with tigecycline combined with azithromycin successively， and other infection therapy plans were dynamically adjusted according to the results of pathogen examination. During the treatment， the patient suffered from suspicious adverse drug reactions such as prolonged QTc interval， elevated lipase and amylase； the clinical pharmacists conducted pharmaceutical care and put forward reasonable suggestions. RESULTS The physician adopted the pharmacists’ suggestion， and the patient was discharged after treatment. CONCLUSIONS For the treatment of severe pneumonia caused by C. psittaci， the characteristics of patients， drugs and pathogens should be taken into account to develop individualized anti-infective treatment. Tetracyclines and macrolides have a definite effect on C. psittaci infection， but attention should be paid to the possible ADR caused by drugs in clinical application.
