Yes. You should let your doctor know if you are taking calcium carbonate because it can decrease the effectiveness of some medications. It can also have negative interactions with some medications especially:

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

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.
