Ibugesic plus contains Ibuprofen
& paracetmol, used for controlling pain & fever.
It is a safe preparation for the pediatric age group.
Few side effects are reported like nausea, vomiting
, skin rash
, etc...but they are mild and well tolerated.
Vaccine induced pain/fever takes a little time to settle down...till then symptomatic treatment should be continued.
So...the medicine prescribed by the pediatrician
is correct...and should be continued as adviced
Wishing your son a speedy recovery.
Thanks & take care.
