OBJECTIVE: To probe into the key points of pharmaceutical care for severe drug-induced thrombocytopenia induced by levofloxacin. METHODS: Clinical pharmacists performed medication analysis and monitoring on patients with severe drug-induced thrombocytopenia

and concluded that thrombocytopenia was most likely induced by levofloxacin sodium chloride injection

the clinicians were advised to stop using the drugs. The clinicians adopted the recommendation and discontinued levofloxacin sodium chloride injection. RESULTS: By discontinuing levofloxacin

along with platelet enhancement and coagulation factor supplement

the condition of the patient eventually improved. CONCLUSIONS: Clinical pharmacists can improve the safety of clinical medication by providing pharmaceutical care for patients.
