Abstract :
Recommendation and concern over vitamin D deficiency has led to widespread use of vitamin D supplements, containing up to 60,000 IU/unit dose (400 IU=10?g) in practice from infantile age. Vitamin toxicity also has increased proportionately. Vitamin D toxicity usually occurs over a time period and presents with hypercalcaemia. Infants are particularly vulnerable to toxicity associated with vitamin D overdose. However, It is rare to find cases of vitamin D intoxication that present with dramatic life-threatening symptoms in children. We present the unique case of acute vitamin D toxicity without hypercalcemia where malnourished child was given vitamin D supplement of higher concentration and presented within two days with signs of lethargy and hypotonia. Vitamin D levels were found to be high and came to normal after four week.
