Vitamin D Replacement: The Effect on Statin-Related Myalgias


The purpose of this project is to determine if Vitamin D supplementation [10,000 international units of cholecalciferol (vitamin D3) by mouth weekly] will decrease the rate of discontinuation of statin therapy due to muscle ache/pain and decrease the occurrence of muscle ache/pain due to statin therapy.
