Hydroxychloroquin and Vitamin D

Recommended Posts

I saw an endrocrine specialist this week due to my continuing high Parathyroid levels and bone loss. He mentioned that Hydroxychloroquin can interfere with Vitamin D absorbtion and, consequently, reduce hypocalcemia. This was not my problem as I have just started taking the medication and had the bone and Vitamin D problem for a long time.

I did notice that when I first started the hydroxychloroquin, my jionts started hurting in a way I have previously identified with low Vitamin D levels. Gradually this pain got better over the couple of months since I started.

Has anyone experienced problems with low Vitamin D levels while on thei medication? If so, was there anything to be done about it?

I've been on Hydroxychloroquin for 10 years, and it's never interfered with my Vita D levels. My doctor has checked my Vita D level, but not because he was worried the Hydroxychloroquin would interfere. You might want to run this by your provider.
