Vitamin D and Related Compounds (Systemic)
Precautions While Using This Dietary Supplement
For individuals taking vitamin D without a prescription
Vitamin D is stored in the body; therefore, when you take more than
the body needs, it will build up in the body. This may lead to poisoning.
Problems are more likely to occur in:
Adults taking 20,000 to 80,000 Units a day and more for several weeks
Children taking 2,000 to 4,000 Units a day for several months.
Remember that the total amount of vitamin D you get every day includes
what you get from foods that you eat and what you take as a supplement.
If you are taking this medicine for a reason other than as a dietary supplement,
your doctor should check your progress at regular visits
to make sure that it does not cause unwanted effects.
Do not take any nonprescription (over-the-counter [OTC]) medicine or dietary
supplement that contains calcium, phosphorus, or vitamin D while you are taking
any of these dietary supplements unless you have been told to do so by your
health care professional. The extra calcium, phosphorus, or vitamin D may
increase the chance of side effects.
Do not take antacids or other medicines containing
magnesium while you are taking any of these medicines. Taking these medicines
together may cause unwanted effects
