This combination of three medications is used to treat heartburn and other symptoms caused by too much acid in the stomach (acid indigestion). Famotidine is a drug that blocks acid release in the stomach and can help stop heartburn and acid indigestion from coming back. Calcium carbonate and magnesium hydroxide are antacids that work quickly to lower acid in the stomach and stop heartburn.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor\'s approval.

Since famotidine reduces the amount of acid in your stomach, it may also change the absorption of certain medications and affect how they work. Some examples of affected drugs include atazanavir, dasatinib, delavirdine, certain azole antifungals (such as itraconazole, ketoconazole), among others. Ask your doctor or pharmacist if any of the medications you take are affected by famotidine and how to manage this interaction.
