Question
The child received a 300,000 unit D3 shot and, 10 days later, experienced symptoms such as vomiting, restlessness, and decreased appetite. Is this a sign of poisoning?
Answer
According to textbooks, children with severe rickets can receive a single intramuscular injection of 300,000 units of D3, but generally do not need to take calcium supplements orally. The symptoms of vitamin D poisoning are not specific and require confirmation through blood calcium and urine calcium tests. Currently, the child only has dry heaves and it cannot be confirmed whether there is poisoning. It is recommended to seek medical attention and temporarily stop taking calcium gluconate.
