In 20 cases, vitamin D was administered orally in place of products supplied in bottles with a similar appearance. At baseline, mean ± SD serum 25(OH)D concentrations in infants allocated to the 4 IU/d vitamin D groups were 45.8 ± 14.1 and 47.6 ± 13.4, respectively for the reference group it was 69.2 ± 16.4 nmol/L. a defective dropper with fluid coming out as a "spurt" rather than the limited flow expected, detachment of the dropper nozzle, etc.Īround one hundred cases of overdose were linked to communication failure between adults leading to administration of duplicate doses, to carelessness, to prescription errors, or to failure to properly understand a prescription. 66 cases of overdose were linked to a defect in the bottle, e.g. In 70 cases, eye exposure to vitamin D was accidental, resulting from mishandling during oral administration.
