Can You Take Calcium with Pantoprazole?

Calcium and pantoprazole can be taken together, but caution is advised due to potential absorption issues. Pantoprazole may reduce the absorption of calcium, particularly calcium carbonate, which could affect calcium levels in the body. It is recommended to separate the intake of these substances to minimize interaction risks.
