question: My father was hospitalised with infection and high fever. He was administered Supacef injection 1.5 mg two times in a day for 7 days. His creatine and blood urea level was 3.2 and 126 on the last day of treatment.  Is it becoz of that antibiotic injection that creatine and urea level increased?  At the the time of admission creatine level was 1.6 and urea 56
