Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that your daughter is suffering from viral infection and the symptoms of
Tonsillitis, fever and cough are all due to it..
As it is a viral infection antibiotics will not help as they can treat bacterial infection and not virus..
Secondly Phenargan contains active ingredient
Promethazine that acs against itchy eyes, runny nose,and
allergy symptoms, therefore it can be given for cough relief..
As it is a viral infection you need to give her supportive treatment to relieve the symptoms as the disease will resolve only once the virus completes its cycle in human body..
You should make her do warm saline gargles, steam inhalation and use a humidifier in your room..
You can continue giving
Calpol to reduce fever and can also do cool sponges on her forehead and extremities..
Give her cough suppressant containing
Dextromethorphan and cough expectorant contatinig Gueifenesin.
Give her plenty of warm fluids and water..
Give her a soft and bland diet and avoid spicy and chilled foods..
Give sufficient rest..
Hope this information helps..
Thanks and regards.
