Dear Healtcare Magic, Our pediatrician recommended 500IU of vitamin D3 (on every alternative day) for my 1month old daughter. All was going well but today, I accidentally dropped three (3) drops of vitamin D3 into her mouth (i.e., 1500IU). I was reading online that a vitamin D3 overdosage can cause vomiting, nausea, weight loss, constipation, and even kidney damage, inter alia. Is there a need to rush her to emergency?

Summarized question: Is vitamin D3 over dose life threatening?
