Aluminum Hydroxide tablets or capsules

What are aluminum hydroxide tablets or capsules?

ALUMINUM HYDROXIDE (Alu-cap®, Alu-tab®, Amphojel®) is an antacid that neutralizes or reduces stomach acid. It helps relieve symptoms of excessive stomach acidity in patients with indigestion, heartburn, gastroesophageal reflux disorder (GERD), or stomach or duodenal ulcers. Aluminum also binds with other salts, called phosphates, in the stomach and prevents them from being absorbed into the body. For this reason, aluminum hydroxide also can help to prevent dangerous increases in phosphates that tend to occur in patients with kidney disease. Generic aluminum hydroxide tablets are available, but not capsules.

What should I tell my health care provider before I take this medicine?

They need to know if you have any of these conditions:
• constipation
• hemorrhoids
• kidney disease
• liver disease
• low blood phosphate levels
• stomach bleeding or obstruction
• an unusual or allergic reaction to aluminum or other antacids, foods, dyes, or preservatives
• pregnant or trying to get pregnant
• breast-feeding

How should I take this medicine?

Take aluminum hydroxide tablets or capsules by mouth. Follow the directions on the prescription label. Swallow the capsules or tablets with a drink of water. Antacids are usually taken after meals and at bedtime, or as directed by your prescriber. Take your doses at regular intervals. Do not take your medicine more often than directed.

Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.
