Thanks for writing to health care magic.
May be he is having ear infection
Is his fever persisting.......
One danger sign he is having is he is very sleepy....
Any baby having lethargy
, poor feeding, seizures, vomiting
etc requires medical attention immediatly
Yes normally we suggest to use only paracetamol
rather than a combination which is not very safe.
I think you kid needs the attention of doctor further investigations after examination
Hope this helps
