What are antacids, and how do they work?

Antacids are a class of drugs used to treat conditions caused by the acid that is produced by the stomach. The stomach naturally secretes an acid called hydrochloric acid that helps to break down proteins. This acid causes the contents of the stomach to be acidic in nature, with a pH level of 2 or 3. (pH levels are a measure of acidity in the stomach: the lower the number, the greater the acidity.) The stomach, duodenum, and esophagus are protected from acid by several protective mechanisms.

Phoslo Patient Information Including Side Effects

Brand Names: PhosLo, PhosLo Gelcap

Generic Name: calcium acetate (Pronunciation: KAL see um AH seh tate)

What is calcium acetate (Phoslo)?

Calcium is a mineral that is needed for many 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 acetate is used to control phosphate levels to keep them from getting to high in people with kidney failure.

Calcium acetate may also be used for purposes other than those listed in this medication guide.

What are the possible side effects of calcium acetate (Phoslo)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Less serious side effects are more likely to occur, such as:

nausea, vomiting, loss of appetite;
constipation;
dry mouth or increased thirst; or
urinating more than usual.

This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about calcium acetate (Phoslo)?

Do not use this medication if you have high levels of calcium in your blood, or if you are also taking digoxin (digitalis, Lanoxin, Lanoxicaps).

Do not take additional calcium supplements unless your doctor has told you to.

Avoid using antacids without your doctor's advice. Use only the specific type of antacid your doctor recommends. Many antacids contain calcium and you could be getting too much of this mineral if you take a calcium antacid with calcium acetate.
