GENERIC NAME: calcium carbonate
BRAND NAME: calcium carbonate 600, calcium carbonate
600 Plus D, calcium carbonate 600 Plus
DRUG CLASS AND MECHANISM:
Calcium is the fifth most abundant element in the
body. Calcium is an important structural component
of bone and teeth and also is necessary for the
normal function of all muscles (skeletal, heart, and
smooth muscles) and nerves as well as the normal
clotting of blood. Prolonged, inadequate intake of
calcium causes weak bones (osteoporosis). Products
containing calcium carbonate are used to increase
the intake of calcium in individuals whose diets are
low in calcium. The National Institutes of Health
recommend 1000 to 1500 mg of calcium per day as part
of a regimen to prevent the loss of bone that is
associated with aging. Calcium carbonate products
contain 40% calcium (absorbable calcium). Therefore,
a 1500 mg tablet of calcium carbonate provides 600
mg of calcium.
PRESCRIPTION:
no
GENERIC AVAILABLE:
yes
PREPARATIONS:
calcium carbonate 600 tablets (600 mg calcium);
calcium carbonate 600 plus D tablets (600 mg calcium
plus 200 IU vitamin D), calcium carbonate 600 plus
tablets (600 mg calcium plus 200 IU vitamin D and
other minerals); calcium carbonate 600 chewable
tablets.
STORAGE:Tablets
should be stored at room temperature, 2-25°C
(36-77°F).
PRESCRIBED FOR:
Calcium-containing products are used as part of a
regimen for preventing and treating osteoporosis in
individuals with low levels of calcium in their
diets. Such regimens also may include vitamin D,
estrogen replacement therapy, and specific
medications for treating osteoporosis, for example,
alendronate.
DOSING:
The usual recommended dose of calcium carbonate for
adults is one tablet twice a day with meals.
DRUG INTERACTIONS:Calcium
products bind to quinolone (e.g., Ciprofloxacin) and
tetracycline (e.g., Sumycin) antibiotics in the
intestine and can prevent their absorption into the
body. To prevent this interaction, doses of
quinolone and tetracycline antibiotics should be
separated by three or more hours from doses of
calcium.
Calcium carbonate-containing products reduce acidity
in the stomach, though there may be a rebound
phenomenon which causes a greater than normal amount
of acid to be produced after the initial
acid-reducing effects of the calcium wear off. The
reduction of acid decreases the absorption of iron
from the intestine. Therefore, doses of calcium and
iron should be separated by a several hours.
Calcium products also bind to Kayexalate (a drug
used to treat high levels of potassium) in the
intestine and, therefore, may interfere with the
action of Kayexalate. Doses of Kayexalate and
calcium products should be separated by several
hours.
PREGNANCY:Use
of calcium supplements during pregnancy appears to
be safe, but such use should be done under the
supervision of a healthcare provider.
NURSING MOTHERS:
Calcium supplements are safe when used by nursing
mothers.
SIDE EFFECTS:
Calcium products rarely cause an upset stomach.
However, excessive intake or absorption of calcium
may lead to increased levels of calcium in the blood
(hypercalcemia) which may cause nausea, vomiting,
decreased appetite, abdominal
pain,
dry mouth and thirst. Severe hypercalcemia may cause
confusion, delirium, stupor and coma.
