tempra, calpol, biogesic, etc are just brand names. you can switch to another brand as long as same paracetamol (active ingredient) and dosage sa packaging. another question is tama ba ang dosage na binigay sa bata dahil depende sa weight ng bata to absorb the medicine to make it effective. another is, depende rin sa sakit. best to consult a pedia. kami, we use calpol.
