In antimicrobial stewardship for neonates, which practice supports safe antibiotic use?

• A. Continue broad-spectrum antibiotics for the full course regardless of cultures.
• B. De-escalate based on cultures and evidence; use narrow-spectrum when possible; monitor exposure.
• C. Never discontinue antibiotics.
• D. Always use combination therapy.

Answer: (B)

In neonatal antimicrobial stewardship, using antibiotics safely hinges on tailoring therapy as soon as information is available. Start with empiric broad coverage when infection is suspected, but actively narrow the treatment as soon as culture results and clinical response permit. De-escalating based on cultures and evidence means switching to a narrower-spectrum antibiotic that targets the identified organism, or stopping antibiotics if cultures are negative and the infant is improving. Monitoring exposure means daily review of the treatment plan to ensure the duration and dose are appropriate, adjusting for organ function, and avoiding unnecessary prolonged use.

This approach minimizes harm: it reduces disruption to the developing microbiome, lowers the risk of antimicrobial resistance, and limits toxicity from drug exposure. Wrong choices would keep broad-spectrum therapy for the entire course, never stopping antibiotics, or using combination therapy automatically; these strategies increase risks without improving safety or outcomes.
