Question
The child experienced frequent vomiting, decreased sleep quality, and reduced appetite after receiving a 300,000 unit D3 injection. Is it possible that the child has vitamin D toxicity?
Answer
According to the textbook, children with severe rickets can be injected with 300,000 units of D3 at once, usually without the need for concurrent calcium supplements. The symptoms of vitamin D toxicity are non-specific and may overlap with symptoms of rickets, making it difficult to determine based solely on symptoms. Confirmation requires tests such as blood calcium and urine calcium levels. Currently, it is not possible to determine toxicity based on dry heaving symptoms alone. It is recommended to take the child to the hospital for examination and temporarily discontinue oral calcium gluconate.
