Description

Antacids are taken by mouth to relieve heartburn, sour stomach, or acid indigestion. They work by neutralizing excess stomach acid. Some antacid combinations also contain simethicone, which may relieve the symptoms of excess gas. Antacids alone or in combination with simethicone may also be used to treat the symptoms of stomach or duodenal ulcers.

With larger doses than those used for the antacid effect, magnesium hydroxide (magnesia) and magnesium oxide antacids produce a laxative effect. The information that follows applies only to their use as an antacid.

Some antacids, like aluminum carbonate and aluminum hydroxide, may be prescribed with a low-phosphate diet to treat hyperphosphatemia (too much phosphate in the blood). Aluminum carbonate and aluminum hydroxide may also be used with a low-phosphate diet to prevent the formation of some kinds of kidney stones. Aluminum hydroxide may also be used for other conditions as determined by your doctor.

These medicines are available without a prescription. However, your doctor may have special instructions on the proper use and dose of these medicines for your medical problem. They are available in the following dosage forms:

Before Using This Medicine

If you are taking this medicine without a prescription, carefully read and follow any precautions on the label. For antacids, the following should be considered:

Allergies—Tell your health care professional if you have ever had any unusual or allergic reaction to aluminum-, calcium-, magnesium-, simethicone-, or sodium bicarbonate-containing medicines. Also, tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Diet—Make certain your health care professional knows if you are on a low-sodium diet. Some antacids contain large amounts of sodium.

Pregnancy—Studies on effects in pregnancy have not been done in either humans or animals. However, there have been reports of antacids causing side effects in babies whose mothers took antacids for a long time, especially in high doses during pregnancy. Also, sodium-containing medicines should be avoided if you tend to retain (keep) body water.

Breast-feeding—Some aluminum-, calcium-, or magnesium-containing antacids may pass into breast milk. However, these medicines have not been reported to cause problems in nursing babies.

Children—Antacids should not be given to young children (under 6 years of age) unless ordered by their doctor. Since children cannot usually describe their symptoms very well, a doctor should first check the child. The child may have a condition that needs other treatment. If so, antacids will not help and may even cause unwanted effects or make the condition worse. In addition, aluminum- or magnesium-containing medicines should not be given to premature or very young children because they may cause serious side effects, especially when given to children who have kidney disease or who are dehydrated.

Older adults—Aluminum-containing antacids should not be used by elderly persons with bone problems or with Alzheimer's disease. The aluminum may cause their condition to get worse.

Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking antacids, it is especially important that your health care professional know if you are taking any of the following:

Cellulose sodium phosphate (e.g., Calcibind)—Calcium-containing antacids may decrease the effects of cellulose sodium phosphate; use with magnesium-containing antacids may prevent either medicine from working properly; antacids should not be taken within 1 hour of cellulose sodium phosphate

Fluoroquinolones (medicine for infection)—Antacids may decrease the effects of these medicines

Isoniazid taken by mouth (e.g., INH)—Aluminum-containing antacids may decrease the effects of isoniazid; isoniazid should be taken at least 1 hour before or after the antacid

Ketoconazole (e.g., Nizoral) or
Methenamine (e.g., Mandelamine)—Antacids may decrease the effects of ketoconazole or methenamine; these medicines should be taken 3 hours before the antacid

Mecamylamine (e.g., Inversine)—Antacids may increase the effects and possibly the side effects of mecamylamine

Sodium polystyrene sulfonate resin (SPSR) (e.g., Kayexalate)—This medicine may decrease the effects of antacids

Tetracyclines (medicine for infection) taken by mouth—Use with antacids may decrease the effects of both medicines; antacids should not be taken within 3 to 4 hours of tetracyclines

Other medical problems—The presence of other medical problems may affect the use of antacids. Make sure you tell your doctor if you have any other medical problems, especially:

Alzheimer's disease (for aluminum-containing antacids only) or
Appendicitis (or signs of) or
Bone fractures or
Colitis or
Constipation (severe and continuing) or
Hemorrhoids or
Intestinal blockage or
Intestinal or rectal bleeding—Antacids may make these conditions worse

Colostomy or
Ileostomy or
Inflamed bowel—Use of antacids may cause the body to retain (keep) water and electrolytes such as sodium and/or potassium

Diarrhea (continuing)—Aluminum-containing antacids may cause the body to lose too much phosphorus; magnesium-containing antacids may make diarrhea worse

Edema (swelling of feet or lower legs) or
Heart disease or
Liver disease or
Toxemia of pregnancy—Use of sodium-containing antacids may cause the body to retain (keep) water

Kidney disease—Antacids may cause higher blood levels of aluminum, calcium, or magnesium, which may increase the risk of serious side effects

Sarcoidosis—Use of calcium-containing antacids may cause kidney problems or too much calcium in the blood

Underactive parathyroid glands—Use with calcium-containing antacids may cause too much calcium in the blood

Some tests may be affected by this medicine. Tell the doctor in charge that you are taking this medicine before you have any tests to determine how much acid your stomach produces.

within 1 to 2 hours or more of taking other medicine by mouth . To do so may keep the other medicine from working properly.

If your stomach problem is not helped by the antacid or if it keeps coming back, check with your doctor.
Using magnesium- or sodium bicarbonate-containing antacids too often, or in high doses, may produce a laxative effect. This happens fairly often and depends on the individual's sensitivity to the medicine.

For patients taking aluminum-containing antacids (including magaldrate):

Before you have any test in which a radiopharmaceutical will be used, tell the doctor in charge that you are taking this medicine. The results of the test may be affected by aluminum-containing antacids.

For patients taking calcium- or sodium bicarbonate-containing antacids :

Do not take the antacid with large amounts of milk or milk products . To do so may increase the chance of side effects.
