Heartburn and indigestion are extremely common during pregnancy. As the baby grows, pressure on the stomach increases, and hormones relax the muscles of the digestive tract, making acid reflux more frequent. Many expecting moms reach for Tums to ease the discomfort. But the question is: Are Tums safe during pregnancy? The short answer is yes — when taken as directed. Tums are generally considered safe for pregnant women and are even recommended by many doctors as a source of both heartburn relief and extra calcium. But there are important things to know about dosage, risks, and alternatives.
1. What Are Tums?
Tums are over-the-counter antacid tablets that contain calcium carbonate as the active ingredient. They work by neutralizing excess stomach acid, providing fast relief from:
- Heartburn
- Acid indigestion
- Sour stomach
Each chewable tablet also provides a dose of dietary calcium, which can support bone health for both mother and baby.
2. Why Heartburn Is Common During Pregnancy
Pregnant women often experience heartburn due to a combination of hormonal and physical changes:
- Hormones: Progesterone relaxes the lower esophageal sphincter (LES), making acid reflux more likely.
- Growing uterus: As the baby grows, the uterus pushes on the stomach, increasing acid backup.
- Slower digestion: Pregnancy hormones slow digestion, keeping food in the stomach longer.
These changes make heartburn almost inevitable for many women, especially in the second and third trimesters.
3. Are Tums Safe During Pregnancy?
Yes. Tums are considered safe for most pregnant women when taken occasionally and within recommended limits. Doctors often suggest Tums as a first-line treatment for pregnancy heartburn because they act quickly and also supply calcium.
In fact, many prenatal care providers specifically recommend Tums over other antacids because of the added calcium benefit.
4. Benefits of Tums During Pregnancy
There are several advantages to using Tums while expecting:
- Fast relief: Works within minutes to ease burning and discomfort.
- Extra calcium: Helps support the mother’s bones and the baby’s developing skeleton.
- Readily available: Found in nearly every drugstore, making them convenient.
- Safe track record: Widely used by pregnant women with few concerns when taken as directed.
5. Risks and Limitations of Tums in Pregnancy
While safe, Tums are not risk-free. Overuse can cause problems, such as:
- Constipation: Calcium carbonate can slow digestion.
- Kidney stones: Too much calcium increases risk.
- Hypercalcemia: Excess calcium in the blood can cause nausea, confusion, or heart issues.
- Milk-alkali syndrome: Rare, but can occur with very high calcium intake.
These risks are mainly a concern if Tums are used in large amounts or for extended periods.
6. Recommended Dosage for Pregnant Women
The safe daily limit depends on the strength of the tablets and medical guidance. Typical recommendations are:
- Regular Strength (500 mg): Up to 12 tablets per day
- Extra Strength (750 mg): Up to 10 tablets per day
- Ultra Strength (1,000 mg): Up to 7 tablets per day
For pregnant women, the limit is often lower — around 5 Ultra Strength tablets or the equivalent per day. Always check with your doctor, especially if you’re already taking prenatal vitamins with calcium.
7. When Tums Should Be Avoided in Pregnancy
Tums may not be safe in certain situations, including:
- Kidney disease: Extra calcium can overload the kidneys.
- History of kidney stones: May increase recurrence risk.
- High calcium levels: If you have hypercalcemia, Tums can make it worse.
- Medication interactions: Tums may interfere with iron or thyroid medicine absorption. Take them at least 2 hours apart.
8. Alternatives to Tums During Pregnancy
If you find yourself needing frequent relief, alternatives may work better:
- H2 blockers (Pepcid, famotidine): Reduce acid production, safe in pregnancy under medical supervision.
- Proton pump inhibitors (Prilosec, omeprazole): Stronger acid reducers, sometimes prescribed for severe reflux.
- Lifestyle changes: Avoiding trigger foods, eating smaller meals, and staying upright after eating often reduce symptoms.
9. Lifestyle Tips for Managing Heartburn in Pregnancy
Along with using Tums safely, these strategies may help reduce discomfort:
- Avoid spicy, fatty, or acidic foods that trigger reflux
- Eat smaller, more frequent meals instead of large ones
- Don’t lie down immediately after eating
- Elevate the head of your bed to reduce nighttime heartburn
- Wear loose-fitting clothing to reduce abdominal pressure

| Remedy | Main Ingredient | Safe During Pregnancy? | Best For |
|---|---|---|---|
| Tums | Calcium carbonate | Yes, in moderation | Quick relief, calcium support |

11. Frequently Asked Questions
Can I take Tums every day while pregnant?
Occasional daily use is fine, but frequent reliance should be discussed with your doctor. Too much calcium can cause health issues.
Are sugar-free Tums safe during pregnancy?
Yes. Sugar-free varieties work the same way and are safe unless your doctor advises otherwise.
Do Tums replace prenatal vitamins?
No. While they provide calcium, they don’t contain folic acid, iron, or other essential nutrients.
Are Tums better than Pepcid in pregnancy?
Tums provide fast relief but don’t last long. Pepcid reduces acid production and works for longer-lasting control of frequent symptoms.
What if Tums don’t help?
If Tums aren’t providing relief, or if you need them more than a few times a week, talk to your doctor about other safe options.
12. When to Call Your Doctor
See your healthcare provider if you experience:
- Heartburn that occurs daily or disrupts sleep
- Difficulty swallowing
- Severe nausea and vomiting
- Unexplained weight loss during pregnancy
- Chest pain that doesn’t improve with antacids
13. Conclusion
Are Tums safe during pregnancy? Yes — when taken in moderation. Tums are a reliable, doctor-approved remedy for occasional heartburn and acid indigestion while expecting. They not only ease discomfort but also provide extra calcium, which supports both mother and baby. However, overuse can lead to constipation, kidney issues, or high calcium levels, so it’s important to follow dosage guidelines and consult your doctor if you need frequent relief.
Bottom line: Tums are safe for short-term use during pregnancy, but for ongoing heartburn, your doctor may recommend additional treatment and lifestyle changes for the healthiest pregnancy possible.
