Medications during pregnancy


Hello Doctor, I have just discovered that I am pregnant (about one month along), but I have been taking medication for gastric ulcers, Sanamidol (Omeprazole - 20mg), daily for the past two months.
Additionally, about two weeks ago, I took Polaramine (2) for two days due to a cold and nasal allergies, Yellowin four times a day, and Besonin Nasal Aq.
(spray) twice a day.
I am concerned about whether these medications could affect the fetus.
Thank you very much for your response! Wishing you a Happy New Year! Sincerely, a worried sister.

Dr. Liao Lingmei reply Pharmacology


Dear Xiaoge Mei: The use of Yollowin and Polaramine during pregnancy is generally considered safe and has minimal impact on the fetus.
Omeprazole and Besonin (I could not find the active ingredient for this medication, but I suspect it is a steroid nasal spray) are classified as Category C in terms of safety for pregnant women (the categories are A, B, C, D, and X, with A being the safest).
This means that the benefits to the mother must outweigh any potential risks to the fetus when considering medication.
Additionally, nasal sprays have a localized effect, and systemic effects are not significant.
Based on this information, I recommend discussing with your physician at your next appointment whether it is necessary to switch to a safer prescription medication for treating ulcers.
Cold medications are symptomatic treatments, and if there are no discomforts, they can be omitted.
Furthermore, if you do not have chronic rhinitis, long-term use of nasal sprays is not recommended.
I hope this information is helpful.
Wishing you good health and congratulations!

More Info


When it comes to medication safety during early pregnancy, it is crucial to understand the potential risks and benefits associated with the drugs you have taken. The first trimester, which includes the first 12 weeks of pregnancy, is a critical period for fetal development, and exposure to certain medications can have implications for both the mother and the developing fetus.


Overview of the Medications
1. Sanamidol (Omeprazole 20mg): Omeprazole is a proton pump inhibitor (PPI) commonly used to treat gastroesophageal reflux disease (GERD) and peptic ulcers. According to the FDA, Omeprazole is classified as a Category C medication. This means that animal reproduction studies have shown an adverse effect on the fetus, but there are no adequate and well-controlled studies in pregnant women. Therefore, it should only be used if the potential benefit justifies the potential risk to the fetus.

2. Polaramine (Dexchlorpheniramine): This is an antihistamine used to relieve allergy symptoms. It is classified as Category B by the FDA, indicating that there are no proven risks in human studies. However, as with any medication, it is advisable to use it only when necessary and under the guidance of a healthcare provider.

3. Yellowin (Chlorpheniramine): Similar to Polaramine, Chlorpheniramine is also an antihistamine and is classified as Category B. It is generally considered safe for use during pregnancy, but again, it should be used judiciously.

4. Besonin Nasal Aq. (Beclomethasone): This is a nasal corticosteroid used to treat nasal congestion and allergic rhinitis. It is classified as Category C, meaning that while it may be effective, its safety during pregnancy has not been fully established. It should be used only if the benefits outweigh the risks.


General Considerations
- Consult Your Healthcare Provider: It is essential to discuss any medications you have taken or are currently taking with your healthcare provider, especially during pregnancy. They can provide personalized advice based on your medical history and the specifics of your pregnancy.

- Risk vs. Benefit: The decision to continue or discontinue medication during pregnancy should be based on a careful assessment of the risks versus the benefits. In some cases, the benefits of treating a condition may outweigh the potential risks to the fetus.

- Monitoring and Follow-Up: If you have concerns about the medications you have taken, your healthcare provider may recommend additional monitoring or follow-up appointments to ensure the health of both you and your baby.

- Lifestyle Modifications: In addition to medication, consider lifestyle modifications that may help manage your symptoms. For example, dietary changes, staying hydrated, and avoiding known allergens can be beneficial.


Conclusion
In summary, while some of the medications you have taken are classified as relatively safe during pregnancy, others carry potential risks. It is crucial to have an open dialogue with your healthcare provider about your medication use and any concerns you may have. They can help you navigate the complexities of medication safety during pregnancy and ensure the best possible outcomes for both you and your baby. Remember, the first trimester is a critical time for fetal development, and careful consideration of any medication use is essential.
