What is calcium carbonate? Why is it used?
Most people know that calcium is needed for strong bones, but it's also needed to help blood vessels and muscles contract and expand, to send messages through the nervous system, and to secrete hormones and enzymes. This is the most abundant mineral in your body and makes up 1%-2% of adult human body weight. Over 99% of it is stored in bones and teeth with the rest stored in blood, muscle, and other tissues.
Bone is a living tissue that constantly breaks down and builds back up. Up until around the age of 30, consuming an adequate amount of calcium with enough physical activity ensures that your body builds more bone than it breaks down. The majority of adult bone mass is acquired by age 18 in girls and 20 in boys. After that, breakdown typically exceeds the amount of bone being built. For this reason, it's essential to maximize bone stores when it's still possible. The amount that you lose after age 30 will be impacted by genetics, ethnicity, physical activity level, sex hormone levels, diet, and gender. You can replace what you lose with the foods you eat and your activity level, but you can't increase how much you store. When bone mass drops and there is a deterioration of bone tissue, osteoporosis can occur. Osteoporosis causes bones to be susceptible to fractures. Depending on the severity of the damage, bones can break from a minor fall, or in severe cases, from sneezing.

What are the side effects of calcium carbonate?
Other side effect due to severe hypercalcemia may include:
Calcium supplements cause rebound stomach acidity.
What is the dosage for calcium carbonate?
- The usual recommended dose of calcium replacement is 1 to 1.2 g given daily in 2 or 4 divided doses with meals.
- The dose for use as an antacid is 2 to 4 tablets per 24 hours not to exceed 7 g a day.
Which drugs or supplements interact with calcium carbonate?
: Calcium can make it difficult for the body to absorb certain medications. Calcium products bind to quinolone (for example, ciprofloxacin) and tetracycline (for example, 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. 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 sodium polystyrene sulfonate (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.
Is calcium carbonate safe to take if I'm pregnant or breastfeeding?
Calcium carbonate (Caltrate 600, Os-Cal 500, Tums Extra, Tums Chewy Delight, and Many Other Brands and Generics) is a prescription drug used as part of a regimen to prevent and treat osteoporosis in individuals with low levels of calcium in their diets and as an antacid for minor upset stomachs. Side effects, drug interactions, dosage, storage, and patient safety information should be reviewed prior to taking any medication.

What Is Gastritis? Causes, Symptoms and Treatment
Gastritis (acute and chronic) is an inflammation of the lining of the stomach Some people have no gastritis symptoms, but when they do occur they may include bloating, belching, loss of appetite, nausea, and vomiting. H. pylori infection and nonsteroidal anti-inflammatory drugs (NSAIDs) are the two main causes of gastritis. Alcohol, caffeine, and high-fat foods also can cause gastritis. Fried, fatty, and spicy foods, and alcohol aggravate gastritis symptoms. Other stomach lining irritants that aggravate symptoms include cigarette smoking, acidic juices, caffeine, tomato products, peppers, and chili powder. Foods that sooth gastritis symptoms, and that help reduce and stop H. pylori infection growth in the stomach include apples, onions, garlic, teas, green leafy vegetables, coconut water, and wheat bran. Gastritis is diagnosed with endoscopy, blood tests, or stool tests. Some people get relief from gastritis symptoms with prescription and non-prescription antacids, histamine blockers like famotidine (Pepcid AC) or ranitidine (Zantac 75), or proton pump inhibitors (PPIs) like omeprazole (Prilosec) and esomeprazole (Nexium). These drugs will not cure gastritis. Complications of gastritis include gastric cancers, MALT lymphoma, renal problems, and death.
Heartburn is a burning sensation experienced from acid reflux (GERD). Symptoms of heartburn include chest pain, burning in the throat, difficulty swallowing, the feeling of food sticking in the throat, and a burning feeling in the chest. Causes of heartburn include dietary habits, lifestyle habits, and medical causes. Treatments for heartburn include lifestyle changes, OTC medication,prescription medication, and surgery.
GERD (Acid Reflux, Heartburn)
Gastroesophageal reflux disease (GERD), also called acid reflux, can cause symptoms like heartburn, chest pain, regurgitation, and nausea. Learn about causes, diagnosis, treatment and prevention.
Learn about osteoporosis, a condition characterized by the loss of bone density, which leads to an increased risk of bone fracture. Unless one experiences a fracture, a person may have osteoporosis for decades without knowing it. Treatment for osteoporosis may involve medications that stop bone loss and increase bone strength and bone formation, as well as quitting smoking, regular exercise, cutting back on alcohol intake, and eating a calcium- and vitamin D-rich balanced diet.
Primary Biliary Cirrhosis (PBC) Treatment
Primary biliary cirrhosis (PBC) is thought to be an autoimmune disorder that involves the deterioration of the liver's small bile ducts. These ducts are crucial to transport bile to the small intestine, digesting fats and removing wastes. Symptoms of PBC are edema, itching, elevated cholesterol, malabsorption of fat, liver cancer, gallstones, urinary tract infections (UTIs), and hypothyroidism. Treatments include ursodeoxycholic acid (UDCA); colchicine (Colcrys); and immunosuppressive medications, such as corticosteroids; obeticholic acid (Ocaliva); and medications that treat PBC symptoms. For PBC that is associated with cirrhosis of the liver, liver transplantation may be indicated in extreme cases.
What Causes High Calcium Levels in Infants?
Elevated levels of calcium in the blood indicate a condition known as hypercalcemia. The causes of high calcium levels may vary with age and other factors. High calcium levels in infants can be caused by excess calcium in food, excessive vitamin D intake, excessive vitamin A intake, primary hyperparathyroidism or an increase in parathyroid hormone (PTH), cancerous tumors, injury to skin or fat tissue, infectious diseases (leprosy and histoplasmosis), immobilization or bed rest, and family history of genetic disorders.
