Which Antibiotic is Best for a Three-Month-Old Baby?

Question

Which antibiotic is most effective for a three-month-old baby, especially for gastrointestinal infections?

Answer

For gastrointestinal infections, Gentamicin is the first choice and has the best effect. As long as the dosage is controlled properly, it should not have a significant impact, as Gentamicin mainly acts in the intestines and is minimally absorbed by the gastrointestinal tract. If considering a change in medication, cephalosporin drugs such as Cefalexin or Cefaclor can be considered, along with medications like Smecta and pepsin for treatment, although the effect may not be as good as Gentamicin.
