Follow all directions on your prescription label and read all the guides or instruction sheets. Use only the recommended dose of cholecalciferol.

It may be best to take cholecalciferol after a meal, but you may take it with or without food. 

While using cholecalciferol, you will need frequent blood tests. You may also need x-rays. 

Your doctor will determine how long to treat you with cholecalciferol. 

Cholecalciferol may be only part of a complete program of treatment that also includes dietary changes and taking calcium and vitamin supplements. Follow your doctor's instructions very closely. 

Learn about the foods you should eat to make sure you get enough calcium and vitamin D in your diet. Your cholecalciferol dose may need to be adjusted as you make changes to your diet. 

Store at room temperature away from moisture, light, and heat.
