Zinc supplementation for pediatric pneumonia.

Question Among young children suffering from pneumonia, zinc deficiency has been documented in many countries. Is supplementation with zinc effective in the treatment and prevention of childhood pneumonia? Answer Several studies reported that zinc supplementation for more than 3 months was effective for preventing pneumonia in children younger than 5 years of age; however, the evidence is not sufficient to confirm its prophylactic properties if it is given for shorter periods of time. Adjunctive zinc supplementation for treatment of pneumonia has failed to show a benefit.
