Calcium carbonate can decrease the absorption of other drugs such as tetracycline antibiotics (e.g., doxycycline, minocycline), bisphosphonates (e.g., alendronate), estramustine, iron, levothyroxine, strontium, and quinolone antibiotics (e.g., ciprofloxacin, levofloxacin). Therefore, separate your doses of these medications as far as possible from your doses of calcium carbonate. Ask your doctor or pharmacist about how long you should wait between doses and for help finding a dosing schedule that will work with all your medications.

Check the labels on all your prescription and nonprescription/herbal products (e.g., supplements, vitamins) because they may contain calcium. Ask your pharmacist about using those products safely.
