<s>[INST] Hi my daughter of 4.5 years old is suffering from cough & fever since yesterday morning.. Can I give her zifi 100 mg ready syrup . Last year doctor had advised her same antibiotic with crocin d s for fever and cough. What should be the dosage for her. [/INST] Hello, I am sorry your daughter is ill. With the symptoms you listed-cough and fever- it is likely that she has a viral respiratory illness.  There are more viruses than bacteria that cause respiratory infections. How high is her fever?  Is her appetite normal? Does she have her usual level of activity?  The severity of a viral respiratory illness is usually less that for a bacterial respiratory illness. WiFi is a brand name for the antibiotic called Definite.  While this is a good antibiotic to treat various bacterial infections, it does not treat viral infections. In fact, no antibiotic does. Plus, WiFi, like all Chat Doctor.  Some of its side effects are:- headache-loss of appetite-bloody or watery stool-dizziness-itchy rash-swelling of face, lips, tongue So for the symptoms you provided, this medicine most probably will not be effective, and it could cause side effects. Based on the information given, I feel it is not a good idea to give her this medicine.  Hope I have answered your query. Let me know if I can assist you further. </s>
