Know Which Antacids Are Prohibited for Pregnant Women and Their Dangers
During pregnancy, 17% to 45% of women experience heartburn due to hormonal changes and the pressure of the fetus on the stomach.[1] To overcome this, expectant mothers often take heartburn medication. Unfortunately, not all products are safe; there are some heartburn medications that are prohibited for pregnant women because their ingredients pose a risk to the fetus.
How can you safely treat heartburn during pregnancy? Is it still safe to continue using heartburn medication throughout the pregnancy? Read the review here!
Are Pregnant Women Allowed to Use Heartburn Medication?

During pregnancy, expectant mothers may use medication to minimize discomfort or stomach pain. However, you must choose products with great care because some medications may contain ingredients that are risky for the health of the fetus.
What heartburn medications are safe for pregnant women? A number of options for heartburn medications that are allowed for pregnant women are those classified as Type B drugs.
Based on animal observations, medications in this category do not pose a threat to fetal development during pregnancy.[2] Examples include cimetidine and famotidine.
Nevertheless, the use of these heartburn medications that are safe for pregnant women should still be done under medical supervision to minimize any adverse effects.
List of Medications to Avoid During Pregnancy

Heartburn medication is widely available at pharmacies and supermarkets and generally does not require a doctor's prescription, but it is important to remember that not all such drugs are safe for pregnant women. Here is a list of medications you should avoid while pregnant:
1. Antacids
Antacid medications are generally safe and risk-free when consumed by non-pregnant individuals. However, their use during pregnancy, especially in the third trimester, has the potential to inhibit contractions due to their magnesium content.[3][4]
In addition, you should be wary of antacids high in sodium, such as Sodium Bicarbonate, as they have the potential to cause fluid retention that triggers swelling.[5]
Furthermore, antacids labeled as aluminum hydroxide or aluminum carbonate should also be avoided because their consumption can lead to constipation issues.
2. Omeprazole
The effect of Omeprazole on pregnant women is actually still unclear. According to reports from the U.S. Food and Drug Administration (FDA), there have been 12 reports of birth defects in pregnant women exposed to omeprazole.[6]
However, findings from the American Journal of Obstetrics and Gynecology state that the consumption of omeprazole for pregnant women does not cause pregnancy complications.[7]
Given this uncertainty and the importance of maternal and fetal health, it is indeed better to avoid using omeprazole during pregnancy.
3. Aspirin
High doses of aspirin will trigger a risk of brain hemorrhage in premature babies.[8] If you require this medication, make sure to consult your doctor before making any decisions.
Potential Dangers of Medication Use

Carelessness in consuming heartburn medication that is unsuitable for pregnant women can cause various problems, such as:
1. Babies Born with Respiratory Disorders
Heartburn suppressants can increase the potential risk of asthma and allergies in babies born. It is unclear what the cause is, but some scientists believe this happens due to the influence of allergies from the medication on the fetus.[9]
2. Impaired Fetal Development
Your body may experience iron deficiency due to medication use. In fact, iron plays a very crucial role in the early stages of pregnancy.
The role of iron in early pregnancy includes the formation of red blood cells, strengthening muscle cells, and ensuring the fetal brain grows optimally.[10] The body's inability to absorb this substance will certainly prevent the fetus from growing to its maximum potential.
3. Worsening Disease
Using inappropriate medication can lead to increased gastric acid production or damage the stomach lining, which in turn will actually worsen the heartburn.
4. Miscarriage
The use of medication in sufficiently high or intense doses can pose serious risks to the fetus. One of the most concerning side effects is the potential for miscarriage. Although in some cases babies may be successfully born into the world, the risk of birth defects remains high.[11]
5. Delayed Delivery
Consumption of aspirin late in pregnancy potentially increases the likelihood of delayed or postmature labor, where the baby takes longer to be born from the womb.
Maintaining health during pregnancy requires extra vigilance, especially regarding medication consumption. Knowing and avoiding heartburn medications that are prohibited for pregnant women is an important step in ensuring a healthy and safe pregnancy.
Avoid the heartburn medications that are prohibited for pregnant women above and never hesitate to discuss with your doctor to obtain choices for heartburn medications that are allowed for pregnant women. Remember, whatever you consume will have an influence on the health of the fetus.
