Hi Chandan sinha, Thanks for writing to health care magic. Ofloxacin is not required for a baby with teething. Antibiotics are required if the baby is having loose stools associated with blood and mucus. In such a scenario we call it as dysentery. Otherwise I do not understand why antibiotics are prescribed for your infant. Continue to ask further queries as required. Hope this helps. Take care.
