Osteoporosis

Effects of 50,000 IU of Vitamin D Medication?

08/04/2008

Question:

My internist has prescribed 50,000 units of Vitamin D once a week. How often should I have my Vitamin D levels checked while on this prescription? At what point does this become toxic? What should I watch for? Thanks. (P.S. I have been diagnosed with Osteoporosis and Vitamin D deficiency. My age is 58.)

Answer:

Many physicians prescribe 50,000 IU of vitamin D once a week for 8 weeks and then recheck your blood level.  If it is normal, they often recommend stopping the mega-dose and resorting to 800 IU per day.
