In this case, it depends mainly on how the child’s mental state is and whether there are very typical symptoms of dehydration. If the child is eating and in good spirits, you can take oral medication at home, such as montelukast and probiotics. If the fever is recurrent, you can also take oral anti-inflammatory drugs, such as cephalosporin antibiotics.
