Initial medication issues?


Hello, I am currently 15 weeks pregnant.
I consulted with my obstetrician due to a cold and received medication while informing them of my pregnancy duration.
However, upon returning home and checking the medications, I found that the first item is classified as a Category D drug, the second and fourth items have no information available online, and the third item is a medication that should not be used in the first trimester.
I have already taken one dose of the third medication.
I am concerned about whether this will affect my baby.

1) DEXTROMETHORPHAN --> Category D
2) 500MG ACETAMINOPHEN
3) Ambroxol 30mg --> Medication not recommended for the first trimester
4) STROCAINE 10mg OXETHAZAINE

Hello: After comparing the medications you are using with Micromedex and the drug labels, the pregnancy categories for the first two medications are as follows: 1) DEXTROMETHORPHAN - Category A 2) ACETAMINOPHEN - Category C.
The third and fourth medications are not categorized.
Detailed information is as follows: 1) DEXTROMETHORPHAN - Category A 2) ACETAMINOPHEN - Category C 3) AMBROXOL - According to the drug label: Animal studies during pregnancy have shown that high doses of AMBROXOL do not harm the fetus; however, as with any medication, it is not recommended to use it during the first trimester of pregnancy.
4) STROCAINE - According to the drug label: For pregnant women or those who may become pregnant, this medication should only be administered when the benefits outweigh the risks.
[The safety of this medication in pregnant women has not been established].
Based on the above information, since you have taken one dose, it should not have any impact.
For your health and your baby's health, please remember to attend your prenatal check-ups regularly!

When it comes to medication safety during pregnancy, it is crucial to understand the potential risks and benefits of any prescribed drugs. Pregnant women should always inform their healthcare providers about their pregnancy status and the gestational age to ensure that any medications prescribed are appropriate and safe for both the mother and the developing fetus.

In your case, you mentioned that you are currently 15 weeks pregnant and have been prescribed several medications, including Dextromethorphan, Acetaminophen, Ambroxol, and Strocain. Let's break down each of these medications based on their safety classifications and potential effects during pregnancy.

1. Dextromethorphan (D Category): Dextromethorphan is classified as a Category D medication, which means there is evidence of risk to the fetus based on human data. While it is commonly used as a cough suppressant, its use during pregnancy should be approached with caution. If you have already taken this medication, it is essential to discuss this with your healthcare provider to evaluate any potential risks to your baby.

2. Acetaminophen (500 mg): Acetaminophen is generally considered safe during pregnancy and is classified as Category B. This means that there is no evidence of risk to the fetus in human studies. It is often recommended for pain relief and fever reduction during pregnancy. However, it is essential to use it at the recommended dosage and not exceed the maximum daily limit.

3. Ambroxol (30 mg): Ambroxol is typically not recommended during the first trimester of pregnancy due to a lack of sufficient safety data. While it is classified as Category C, indicating that risk cannot be ruled out, it is generally advised to avoid its use during the first three months of pregnancy unless absolutely necessary. Since you mentioned that you have already taken this medication, it would be wise to consult your healthcare provider for further guidance.

4. Strocain (10 mg): Strocain, which contains Oxethazain, is used as a local anesthetic. There is limited information available regarding its safety during pregnancy, and it is not commonly discussed in pregnancy safety literature. It is essential to consult with your healthcare provider about the necessity of this medication and any potential risks associated with its use during pregnancy.

In summary, while Acetaminophen is generally safe, the use of Dextromethorphan and Ambroxol during pregnancy should be closely monitored, especially given their classifications and the potential risks involved. If you have concerns about the medications you have taken or the prescriptions you have received, it is crucial to have an open and honest conversation with your healthcare provider. They can provide personalized advice based on your specific situation and help you weigh the risks and benefits of continuing any medication.

Additionally, if you experience any unusual symptoms or have concerns about your pregnancy, do not hesitate to seek medical attention. Your healthcare provider is your best resource for ensuring a healthy pregnancy and addressing any medication-related concerns you may have.
