Is It Safe To Take Tums While Pregnant?

Tums — an over-the-counter antacid that uses calcium carbonate to neutralize the acid in the esophagus and stomach — is effective in treating heartburn, indigestion, and sour stomach (per Tums). Registered Pharmacist Rami Khatib told Verywell Family that for pregnant women experiencing heartburn, Tums are a safe option at any point during pregnancy. Not only are they generally trusted, but they can also boost calcium levels (per GoodRX Health). Pregnant women have a higher recommended calcium intake of 1,000 mg to 1,300 mg per day and the calcium carbonate in Tums can help women reach those goals.

Like with most things, however, it’s all about moderation. Dr. Khatib told Verywell Family that pregnant women should be careful not to exceed 2,500 mg of calcium in a day, as too much calcium can cause constipation, kidney stones, and irregular heartbeat, as well as diminish the body’s ability to absorb essential minerals, like iron and zinc. It can also lead to low calcium in the baby. For that reason, it is recommended that pregnant women limit themselves to 15 regular strength Tums within a 24-hour period. Nevertheless, women with chronic kidney disease should first consult their doctors before taking Tums, as antacids can disrupt electrolyte levels in the body.
