My sons age was 8 years 10 months. 5 days back he had a urine passage with brown colour. We went through a urine test and near by rmp said that some blood was mixing with urine and coming out in that way and he prescribed cefolac dt 100 tablets for days twice a day. After using 2 doses urine become normal but today (after using 8 tablets) )again urine came out in brown colour. I was getting tensed again. What is the problem and suggest me what to do. Is there anything wrong in his system? Please help me.
