Methods: A retrospective analysis of 20 cases of cefradine-induced hematuria in children admitted to our hospital in the past 11 years was conducted. The age of onset, dosage of drug, times of administration and rate of instillation were observed, and the causes of hematuria were analyzed. Results: Hematuria occurred in 17 infants and young children (85%). The drug dose was too high and the instillation rate was too fast. The routine administration of one dose could cause hematuria in children, but the prognosis was good. Conclusion: The pediatric clinical medication strictly grasps the principle of medication and uses it rationally to avoid all kinds of adverse reactions after medication.
