Dr. Cai Yonglong reply Obstetrics and Gynecology


In early pregnancy, specifically within 8-9 weeks, the impact of medications is minimal (as implantation has not yet occurred).
Moreover, most of the medications you have taken are generally considered safe.
Please visit an obstetrics and gynecology clinic.

More Info


When it comes to the use of medications during pregnancy, particularly in the context of gastroenteritis, it is essential to understand the potential effects of these medications on fetal development. Based on the information provided, you took several medications after experiencing symptoms of gastroenteritis, and you are now concerned about their impact on your baby, who is currently 12 weeks and 4 days old.

Firstly, let's break down the medications you mentioned:
1. Acetaminophen (利克痛錠): This is generally considered safe during pregnancy and is often recommended for pain relief and fever reduction. It falls under Category B for pregnancy safety, meaning that there is no evidence of risk in humans.

2. Butylscopolamine (必克炎腸溶膜衣錠): This medication is used to relieve cramps and spasms in the gastrointestinal tract. While there is limited data on its use during pregnancy, it is generally considered to have a low risk.

3. Loperamide (安痢膠囊): This is used to treat diarrhea. It is also classified as Category B, indicating that it is likely safe for use during pregnancy when taken as directed.

4. Ondansetron (吐平錠): This medication is commonly used to prevent nausea and vomiting. It is classified as Category B, but some studies have raised concerns about its use in the first trimester. However, the overall consensus is that it is relatively safe when necessary.

5. Ibuprofen (伊普錠): This nonsteroidal anti-inflammatory drug (NSAID) is generally advised against during pregnancy, especially in the third trimester, due to potential risks to the fetus. However, short-term use in the first trimester is sometimes considered acceptable.

6. Proton Pump Inhibitors (胃沒莎膜衣錠): Medications like omeprazole are often prescribed for acid-related disorders. They are classified as Category C, which means that risk cannot be ruled out, but they may be used if the benefits outweigh the risks.

7. Simethicone (樂爾爽片): This is an anti-foaming agent used to relieve bloating and discomfort caused by gas. It is generally considered safe during pregnancy.

Given that you took these medications for only a short duration and that you are currently in your first trimester, the risk of significant harm to your baby is relatively low. The critical period for fetal development is during the first trimester, and many medications have been studied for their effects during this time. Most of the medications you mentioned are either considered safe or have a low risk profile.

However, it is essential to consult with your healthcare provider about your specific situation. They can provide personalized advice based on your medical history and the medications you took. If you have any ongoing concerns about your pregnancy or the health of your baby, it is crucial to have open communication with your obstetrician or healthcare provider.

In summary, while it is natural to worry about the effects of medications taken during pregnancy, the medications you listed generally have a low risk of causing harm to your baby, especially given that you only took them for a short period. Always consult with your healthcare provider for the most accurate and personalized advice regarding medication use during pregnancy.
