What is the most important information I should know about calcium carbonate?
Do not take calcium carbonate or
antacids containing calcium without first talking to
your doctor if you take other medications. Calcium can decrease the effects of many other
medicines by binding to them or by changing the
acidity of the stomach or the urine.
Take calcium with meals to increase its absorption by the body, unless otherwise
directed by your doctor.
What is calcium carbonate?
Calcium is a mineral that is found naturally in foods. Calcium is necessary for many
normal functions of the body, especially bone formation and maintenance. Calcium can also bind
to other minerals (such as phosphate) and aid in their removal from the body.
Calcium carbonate is used to prevent and to treat calcium deficiencies.
Calcium carbonate may also be used for purposes other than those listed in this
medication guide.
What should I discuss with my healthcare provider before taking calcium carbonate?

Achromycin V, and others), demeclocycline (Declomycin), doxycycline (Vibramycin, Monodox,
Doxy, and others), minocycline (Minocin, Dynacin, and others), or oxytetracycline (Terramycin,

explain them to you.

Chew the chewable forms of calcium carbonate completely before swallowing.
Use the calcium carbonate powder as directed. Allow the powder to dissolve completely,
then consume the mixture.
Shake the calcium carbonate suspension well before measuring a dose. To ensure that
you get the correct dose, use a dose-measuring spoon or cup, not a regular table spoon to measure
the liquid. If you do not have a dose-measuring device, ask your pharmacist where you can get
one.
Take calcium with meals to increase its absorption by the body, unless otherwise
directed by your doctor.
Store calcium carbonate at room temperature away from moisture and heat.

Symptoms of a calcium overdose include nausea, vomiting, decreased appetite,
constipation, confusion, delirium, stupor, and coma.
