MUMBAI: A Thane-based consumer has alerted the food and drug administration about iron pieces being found in a medically-prescribed iron tablet. The content of elemental iron in the tablet, prescribed for anaemia or lack of red blood cells, was way above permissible limits. FDA commissioner Mahesh Zagde has directed the Himachal Pradesh-based Galpha Laboratories to withdraw the entire stock of the product from Maharashtra. Simultaneously, the FDA has told 76,000-odd medical stores, public health and medical education departments not to prescribe the product.
