Drug Interaction Report

By reducing the acidity level in the stomach, medications like calcium carbonate may interfere with the absorption of heme iron polypeptide into the bloodstream and reduce its effectiveness. If you require treatment with both medications, it is recommended that you take heme iron polypeptide at least 2 hours before or 2 hours after calcium carbonate to help minimize the impact of the interaction. Talk to your doctor or pharmacist if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Calcium absorption may be increased by taking it with food. However, foods high in oxalic acid (spinach or rhubarb), or phytic acid (bran and whole grains) may decrease calcium absorption. Calcium may be taken with food to increase absorption. Consider spacing calcium administration for at least 2 hours before or after consuming foods high in oxalic acid or phytic acid.
