my 3 years old kid is having fever from last 12 days

Hi,
i am living in india, and my kid is having fever from last 12 days
earlier when we took her to doctor the doctor prescribed her
moxikind syrup and
ibugesic plus when there is fever at min interval of 6 hours and if fever came inbetween 6 hours give her meftal p

first the fever tendency reduced in 5 days and then it started again
and then when we consulted doctor the doctor gave her

zifi-100 + mits linctus dx for cough + alrid + ibugesic and meftal p when required

but even after 5 days she developed pain in her year so he again changed the antibiotic zifi 100 to claribid and ear drops otogesic
its been two days she's on claribid
but now it is getting me worried as even now the fever goes up to 102 comes to normal when ibugesic or meftal -p is given

please recommend

one more thing i would like to add is that she is not having any cough or cold now, but do have ear pain and constipation
