Official title
A Randomized, Controlled Trial of High Dose vs. Standard Dose Vitamin D for Aromatase-Inhibitor Induced Arthralgia in Breast Cancer Survivors
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is being done to look at the difference, if there is a difference between two different doses of Vitamin D and the reduction of joint/muscle pain (arthralgia)that is caused by taking anti-estrogen medications (aromatase inhibitors) by breast cancer patients. The investigators hope to learn if taking a higher dose of Vitamin D is a good way to prevent aromatase inhibitor arthralgia (AIA).
