What is the zinc dose recommended per day for infants under 6 months with acute diarrhea?

• A. 20 mg
• B. 10 mg
• C. 5 mg
• D. 15 mg

Answer: (B)

Zinc helps shorten the duration and lessen the severity of acute diarrhea and supports intestinal healing, so the amount given is tailored to the child’s age. For infants under 6 months, the recommended daily amount is 10 mg of elemental zinc, typically continued for about 14 days. This smaller dose reflects their smaller size and zinc needs, while still providing the therapeutic benefit. In contrast, older children (6 months to 5 years) usually receive a higher dose, around 20 mg daily for 14 days. Doses like 5 mg or 15 mg do not align with standard guidelines for this age group in the context of acute diarrhea.
