My child is 4y4m, he had some vomitting bouts. first twice in two days and then once 3-4 times in an hour, which is when we took him to a doctor. He was presribed lanzol junior 30mg, Now while he hasn't thrown up in last 24 hrs, he's running fever around 100 or 101 deg F.. It subsides when we administer crocin syrup but then comes back in a few hours. Thus fever is most concerning right now... There's hasn't been much coughing all this while.. Do we need any additional medication?
