This medication is used to treat the symptoms of too much stomach acid such as stomach upset, heartburn, and acid indigestion. Aluminum hydroxide is an antacid that works quickly to lower the acid in the stomach. Liquid antacids usually work faster/better than tablets or capsules.
This medication works only on existing acid in the stomach. It does not prevent acid production. It may be used alone or with other medications that lower acid production (e.g., H2 blockers such as cimetidine/ranitidine and proton pump inhibitors such as omeprazole).
OTHER USES: This section contains uses of this drug that are not listed in the approved labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
Aluminum hydroxide is also used to lower phosphate levels in certain kidney conditions (usually in capsule form).
