Tums is generally considered safe to use during pregnancy for relieving heartburn. It is an over-the-counter antacid containing calcium carbonate, which can provide supplemental calcium for both the mother and baby while neutralizing stomach acid to reduce heartburn discomfort.
Safety During Pregnancy
- Many OB/GYNs have been prescribing Tums during pregnancy for years as it is effective and safe when taken in recommended doses.
- Tums provides supplemental calcium which is beneficial since pregnant women need about 1,000 to 1,300 mg of elemental calcium per day.
- Calcium carbonate, the active ingredient in Tums, is not expected to increase the risk of birth defects or pregnancy complications when used as directed.
Dosage and Usage Tips
- It is generally recommended not to exceed 10 to 15 regular strength tablets (each 500 mg calcium carbonate) in 24 hours, and usage beyond two weeks should be under medical supervision.
- Tums should be taken as needed, usually every 4 to 6 hours, but not excessively to avoid risks.
- Taking Tums separately from iron supplements (at least 1-2 hours apart) is advised since calcium can interfere with iron absorption.
Potential Side Effects
- Possible side effects include constipation, nausea, stomach upset, and increased risk of kidney stones if overused.
- Tums can reduce iron absorption and may interact with thyroid medications, so timing between those medications and Tums should be spaced.
Alternatives and Precautions
- Other safe antacids include magnesium hydroxide and H2 blockers like Pepcid AC.
- Some antacids like sodium bicarbonate or bismuth subsalicylate should generally be avoided during pregnancy.
- Always consult a healthcare provider before starting antacids or if symptoms worsen.
In summary, Tums is safe for occasional use in pregnancy when taken according to guidelines, provides beneficial calcium, and helps manage pregnancy-related heartburn effectively.
