Hi, I had gone through your question and understand your concerns.
You can give Meftal P , in prescribed doses it is safe to use , but better option will be to use single medicine plus tepid sponging if
fever persists .If you are giving it (
Meftal-P) at eight hour interval , dose come out nearly 4 ml , ( giving 5 ml is in safe limit , as it has good safety margin and one dose in not going to cause harm).
Do consult your doctor if fever persists to rule out cause other than
vaccination ( as
hepatitis and
prevenar usually does not cause high and sustained fever).
Hope this answers your question. If you have additional questions then please do not hesitate in writing to us.
Wishing your son good health.
