The students of the Upper Grade Middle English (UGME) School at Gopinathpur were provided the supplements as part of a government initiative to arrest anaemia instances among the young population.
The children are in the age group of five and 13 years.
Gopinathpur is about 70 km from the state capital Bhubaneswar.
Although the children were supposed to consume the tablets after their mid-day meal, they took those on empty stomachs, district collector N.K. Nayak told IANS.
As a result, they developed vomiting tendencies and felt dizzy. The schoolchildren were immediately taken to the Puri district headquarter hospital where they received treatment.
"Most of them have been discharged after treatment. Only four-five children have been kept at the hospital for further observation," Nayak said.
Chief Minister Naveen Patnaik has ordered the local administration to investigate the incident and submit a report to the government at the earliest.
