Considering your baby to be 2months approx 4 to 4.5kg weight you can give ibugesic 10mg/kg per dose that will be 2ml approx....but better you give plain paracetamol that is more safe and single drug and ibugesic plus syrup is combination of pcm and ibuprofen....
If your child is active and there are no other symptoms you can think it is a viral fever and does not need antibiotics or hospital checkup. Give paracetamol 4th hourly and observe her any other signs for 3 days. In the case there are any other trouble, immediately take her to a doctor.
No, Mr. lybrate-user do not give paracetamol routinely after immunisation/vaccination. It is only given when there is pain or fever. And it does not interfere with vaccine effect. Please also check the dose from your pediatrician as 6 drops or more?
Thanks for your query on Lybrate
"as" per your clinical history is concerned it is a common cause, so you are giving right medications for it and no other gel is required at all, so record body temperature up to 48 hours if no further rise in body temperature then no problem and if comes then do blood test (cbc with differential).
Hope that helps.
