I have been taking Arimidex .5mg every 3 days for about 2-3 years now, I could say so far so good except that my blood work came back showing a vitamin D deficiency, how bad I do not know yet until my copy arrives in the mail.
The nurse called me this morning and told me to start on 2000IU of Vit. D3 per day for a month then cut it down to 1000IU per day. So based on the fact they called me I am guessing I am very deficient and not just borderline. I have actually been feeling depressed and lethargic lately which is why I had the test(I convinced myself I was anemic).
I did some searching and came across an article which said 1 3rd of Arimidex patients had a vitamin D deficiency, I can not find it now but here is an article that is more explanatory:
Vitamin D may lessen the pain for those on Arimidex - Breast Cancer Blog
I have never had any joint pain, I believe that is linked to having low Estradiol, but according to the link, vitamin D deficiency could be caused by a direct action of Arimidex in the liver which could explain my case.
So with all that said I was wondering if anyone else here on Arimidex has found themselves to have a vitamin D deficiency.
