Pregnancy brings joy and excitement — but it also comes with its share of discomforts. One of the most common is heartburn. As hormones change and your growing baby presses on the stomach, acid reflux becomes a regular companion for many expecting mothers. Naturally, the question arises: Are Tums safe to take while pregnant? The short answer is yes, when taken occasionally and in moderation. In fact, Tums are one of the most widely recommended over-the-counter remedies for pregnancy-related heartburn. But like any medication, there are important things to know about safe use, dosage, and potential risks.
1. What Are Tums?
Tums are a brand of antacid tablets. Their active ingredient is calcium carbonate, which neutralizes stomach acid on contact. Tums are commonly used to relieve:
- Heartburn (acid reflux)
- Acid indigestion
- Sour stomach
Each tablet also provides a dose of calcium, which can support bone health — a nice bonus during pregnancy when calcium needs are higher.
2. Why Is Heartburn So Common in Pregnancy?
Several changes in the body contribute to frequent reflux while pregnant:
- Hormones: Progesterone relaxes the lower esophageal sphincter (LES), allowing acid to escape upward.
- Growing uterus: As the baby grows, pressure on the stomach pushes acid back into the esophagus.
- Slowed digestion: Hormonal shifts slow digestion, increasing the chance of reflux.
These changes mean that even women who never had heartburn before may experience it during pregnancy.
3. Are Tums Safe to Take While Pregnant?
Yes. Tums are generally safe for most pregnant women when taken as directed. Doctors often recommend Tums as a first option for mild to moderate pregnancy-related heartburn. They are fast-acting, widely available, and add extra calcium to your diet.
However, moderation is key. Overuse can lead to complications, so Tums should not be used as a daily supplement unless advised by your healthcare provider.
4. Benefits of Tums During Pregnancy
Using Tums can offer several advantages for expecting mothers:
- Immediate relief: They work within minutes to neutralize stomach acid.
- Calcium boost: Each tablet adds to your daily calcium intake, supporting bone and tooth development in your baby.
- Safe profile: Long history of use in pregnant women with minimal risks when used responsibly.
- Easy access: No prescription needed, available at nearly any pharmacy.
5. Risks of Taking Too Many Tums
While safe in moderation, excessive use of Tums during pregnancy can cause problems:
- Constipation: A common side effect of calcium carbonate.
- Kidney stones: Too much calcium may increase the risk.
- Hypercalcemia: Excess calcium in the blood can cause nausea, confusion, and abnormal heart rhythms.
- Milk-alkali syndrome: Rare but serious condition from chronic overuse, which can damage the kidneys.
This is why sticking to the recommended dosage is so important.
6. Safe Dosage of Tums During Pregnancy
General guidelines for maximum daily Tums use:
- Regular Strength (500 mg): Up to 12 tablets daily
- Extra Strength (750 mg): Up to 10 tablets daily
- Ultra Strength (1,000 mg): Up to 7 tablets daily (often limited to 5 tablets during pregnancy)
These are general recommendations. Your doctor may advise a lower maximum depending on your diet, calcium intake, and overall health.
7. When Tums Should Be Avoided
Even though Tums are safe for most expecting mothers, some situations call for caution:
- Kidney disease: Excess calcium can worsen kidney function.
- History of kidney stones: May increase recurrence.
- High blood calcium levels: Tums can make this condition worse.
- Medication interactions: Tums can interfere with absorption of iron or thyroid medications. Always space doses by at least 2 hours.
8. Alternatives to Tums During Pregnancy
If you find you need relief more often than Tums can provide, other safe alternatives exist:
- H2 blockers: Such as famotidine (Pepcid), safe under medical supervision.
- Proton pump inhibitors (PPIs): Such as omeprazole (Prilosec), sometimes prescribed for severe reflux.
- Lifestyle adjustments: Avoiding trigger foods, eating smaller meals, and staying upright after eating.
9. Natural Ways to Reduce Heartburn in Pregnancy
Alongside occasional use of Tums, simple lifestyle habits can reduce reflux episodes:
- Eat smaller meals throughout the day
- Avoid spicy, fatty, and acidic foods
- Don’t eat close to bedtime
- Sleep with your upper body elevated
- Stay hydrated but avoid drinking large amounts with meals
- Wear loose-fitting clothing

11. Frequently Asked Questions
Can I take Tums every day while pregnant?
Occasional daily use is fine, but if you need them multiple times every day, check with your doctor. Frequent heartburn may require stronger treatment.
Are sugar-free Tums safe in pregnancy?
Yes, sugar-free Tums are safe and work the same way as regular Tums.
Do Tums interfere with prenatal vitamins?
Yes, they can affect iron absorption. Take Tums and prenatal vitamins at least 2 hours apart.
Do Tums replace calcium supplements?
No. While Tums contain calcium, they don’t provide the full range of nutrients needed during pregnancy. Continue taking prenatal vitamins as prescribed.
What if Tums don’t help?
If heartburn persists despite using Tums, consult your doctor. Stronger but safe options may be available.
12. When to Call Your Doctor
Contact your healthcare provider if you experience:
- Severe or daily heartburn despite antacids
- Difficulty swallowing
- Unexplained weight loss
- Severe nausea or vomiting
- Chest pain that is not clearly related to meals
13. Conclusion
Are Tums safe to take while pregnant? Yes, when used occasionally and within recommended limits. They are a trusted, effective option for quick heartburn relief and provide an extra boost of calcium. However, daily or excessive use can lead to constipation, kidney issues, or too much calcium in the blood. If you find yourself needing Tums often, or if symptoms become severe, your doctor can help you find safer long-term strategies.
Bottom line: Tums are a safe ally for occasional pregnancy heartburn, but they should be used wisely. Combine them with lifestyle changes and medical guidance for the healthiest pregnancy experience.
