Aluminum hydroxide is an antacid available in over-the-counter (OTC) medicines that relieves heartburn, acid indigestion, sour stomach, and upset stomach. Aluminum hydroxide can be found in heartburn medicines that contain more than one antacid active ingredient. It also can be in medicines that not only treat heartburn, but other symptoms as well, such as gas.
Aluminum hydroxide is approved by the U.S. Food and Drug Administration (FDA) and is safe and effective when used according to label directions. Antacids containing aluminum hydroxide may interact with certain prescription drugs. If you are taking a prescription medicine, do not take an OTC aluminum hydroxide antacid without checking with your doctor or other healthcare professional.
*Aluminum hydroxide may not be contained in all products sold under these brands. Please read the OTC Drug Facts label carefully.
