My 10 month old daughter is having loss of appetite, vomiting on in-taking fluid milk formula especially at nights , disturbed sleep and slight discomfort in her urinary area. She recovered from a marginal fever 2 days back after having it for 3 days. She had no white matter in stool, however, her stools looked little bit of green but predominantly brown. We visited the doctor as her vomiting and loss of appetite still persisted. She is being administered Zanocin 50 ml 5ml till 6 days. She did not have a sore throat or running before starting this medication. Is this a side effect of this medication?
