We examined a case of a 4-year-old boy who experienced severe bone pain and related symptoms after taking high doses of vitamin A for three months. Despite typical liver-related complications usually associated with vitamin A toxicity, he presented with significant musculoskeletal issues and skin changes. Following the discontinuation of vitamin A, the boy showed a remarkable recovery within two months. This case highlights that excessive vitamin A intake can lead to serious bone pain and other health problems, though he did not develop liver disease as expected.

ATRA shows mixed effects on pain
We explored the effects of all-trans retinoic acid (ATRA) when combined with dexamethasone and alpha-interferon in treating advanced multiple myeloma. Out of 10 treated patients, eight completed the regimen.

Notably, three experienced a stable plateau phase with improvement in their overall performance and relief from bone pain. However, only two showed a lasting partial response, while three patients did not improve.

Thus, while there was some positive impact on bone pain, further research is needed to confirm these findings and assess ATRA's full potential.

I used it for a certain period, but my doctor advised against taking it during pregnancy due to potential side effects like dry skin, bone pain, and dry eyes. I felt apprehensive and stopped, but before that, I found it to be highly effective, similar to Roaccutane.
