Can You Take Tums While Pregnant?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Yes, Tums are generally considered safe to take during pregnancy for heartburn relief. The active ingredient calcium carbonate provides both antacid benefits and supplemental calcium, which pregnant women need increased amounts of. The American College of Obstetricians and Gynecologists lists calcium carbonate as a Category A medication, meaning extensive studies show no risk to the developing baby. However, you should limit intake to no more than 6-8 tablets per day to avoid excessive calcium consumption. Always consult your healthcare provider before starting any new medication during pregnancy, even over-the-counter options like Tums, to ensure it's appropriate for your specific situation.
