ALUMINUM HYDROXIDE
Combination drugs: Co-Magaldrox, Maalox Plus®, Maalox®, Mucaine®, Mylanta®, Tempo® Tablets
Aluminum hydroxide acts as an antacid and is most commonly used in the treatment of heartburn, gastritis, and peptic ulcer. This drug is also sometimes used to reduce absorption of phosphorus for people with kidney failure.
Aluminum hydroxide is found in a variety of antacids. People should read the ingredient label for over-the-counter (OTC) drugs carefully before purchase to know exactly what they contain.

Interactions with Dietary Supplements
Alginates
A thick gel derived from algae has been used together with aluminum antacids to treat
heartburn. Together, alginate gel and antacid were more effective at relieving
symptoms1 and improving healing.2 Alginate is believed to work by
physically blocking stomach acid from touching the esophagus. According to these studies, two
tablets containing 200 mg alginic acid should be chewed before each meal and at bedtime.
Calcium
Aluminum hydroxide may increase urinary and stool loss of calcium.3 Also, aluminum
is a toxic mineral, and a limited amount of aluminum absorption from aluminum-containing
antacids does occur.4 As a result, most doctors do not recommend routine use of
aluminum-containing antacids.5
Other types of antacids containing calcium or
magnesium instead of aluminum are available.
Citrate
Several studies have shown that combination of citrate, either as calcium citrate supplements
or from orange and lemon juice, with aluminum-containing antacids increases aluminum levels in
the body.6 7 8 Calcium in forms other than calcium citrate
has been shown to not increase aluminum absorption.9 Drinking 7–10 ounces of
orange juice provides sufficient citrate to be problematic.10 11 Intake
of 950 mg calcium citrate greatly elevates aluminum absorption.12 People with renal
failure may be at particular risk of kidney damage due to elevated aluminum levels if they
combine aluminum hydroxide with citrate.13
Folic
acid
Folic acid is needed by the body to utilize
vitamin B12. Antacids,14 including aluminum hydroxide, inhibit folic acid
absorption. People taking antacids are advised to supplement with folic acid.
Phosphorus
Depletion of phosphorus may occur as a result of taking aluminum hydroxide. For those with
kidney failure, reducing phosphorus absorption is the purpose of taking the drug, as excessive
phosphorus levels can result from kidney failure. However, when people with normal kidney
function take aluminum hydroxide for extended periods of time, it is possible to deplete
phosphorus to unnaturally low levels.
