Vitamin D Supplements - Dosing Errors in Infants

June 16, 2010

FDA issued a warning regarding overdose potential for vitamin D supplements in infants.  Some manufacturers package vitamin D supplements with droppers that could allow excessive dosing to infants. Vitamin D 400 international units (IU) is recommended by the American Academy of Pediatrics for all breast-fed infants to promote healthy bone formation. FDA recommends droppers with clear markings that cannot hold more than 400 IU. Use the dropper originally packaged with the supplement. Consult with a healthcare provider if parents or caregivers are unable to accurately administer the supplement to their child. Common adverse events linked to the vitamin D include nausea, vomiting, decreased appetite, muscle weakness, muscle or joint pain, frequent thirst and urination, constipation, abdominal pain, confusion, and fatigue.  Kidney damage can occur in more serious cases.
