What are the risks of taking calcium carbonate?

The risks of taking calcium carbonate generally consist of negative interactions with medications or medical conditions. You should discuss with your doctor the medications you are currently taking, especially:

  • calcitriol
  • digoxin
  • etidronate
  • phenytoin
  • doxycycline
  • minocycline
  • tetracycline.

Vitamin D may cause too much calcium absorption. Do not use any medications within two hours of taking calcium carbonate, which can decrease their effectiveness. If you have experienced stomach disorders, kidney disease, kidney stones, or a disorder of the parathyroid gland, let your doctor know before you begin taking calcium carbonate.
