Medications during pregnancy


Hello, Pharmacist Liao.
I unknowingly became pregnant and took the following medications: 1.
Ketorolac 2.
Peace 3.
Periactin 4.
Novamine.
I am concerned about whether these medications have affected my unborn baby.
Thank you for your response.

Dr. Liao Huiling reply Pharmacology


Hello Yuling: I sincerely apologize for the delay in responding to your email, as I just saw your message.
Given your situation, you are likely in the early stages of pregnancy.
During this period, it is important to be aware of teratogenic medications that could lead to miscarriage or affect the development of the fetus's limbs and organs.
The four medications you are taking are all non-teratogenic, and since they are only taken for a short duration, they should not have any impact on your baby.
Please rest assured! Thank you for your message!

When it comes to medication safety during pregnancy, it is crucial to understand the potential risks and benefits associated with the use of various drugs. The safety of medications can vary significantly depending on their classification by the FDA (Food and Drug Administration) and the specific circumstances of each pregnancy.
In your case, you mentioned taking the following medications: 1. Ketorolac, 2. Peace (likely referring to a brand name), 3. Periactin (Cyproheptadine), and 4. Novamine (likely a brand name for a medication containing diphenhydramine or similar). Let's break down the safety profiles of these medications based on available data.

1. Ketorolac: This medication is a nonsteroidal anti-inflammatory drug (NSAID) often used for pain relief. Ketorolac is classified as a Category C drug by the FDA, which means that while animal studies have shown adverse effects on the fetus, there are no adequate and well-controlled studies in pregnant women. It is generally advised to avoid NSAIDs, especially in the third trimester, due to the risk of premature closure of the ductus arteriosus in the fetus and potential complications during labor.

2. Peace: Without specific information on the active ingredient in "Peace," it is challenging to provide a definitive answer. If it contains a sedative or antihistamine, it may have varying effects during pregnancy. It is essential to consult with a healthcare provider for specific information regarding this medication.

3. Periactin (Cyproheptadine): This medication is an antihistamine that is sometimes used to treat allergies and as an appetite stimulant. 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 should be used only if necessary and under the guidance of a healthcare provider.

4. Novamine: Similar to "Peace," without knowing the specific active ingredient, it is difficult to assess its safety. If it is an antihistamine or a combination medication, it may have different implications for pregnancy. Again, consulting with a healthcare provider is crucial.

Given that you took these medications without knowing you were pregnant, it is understandable to be concerned about their potential effects on your developing baby. While some medications may pose risks, many factors influence the actual risk, including the timing of exposure during pregnancy, the dosage taken, and individual health factors.

It is essential to discuss your medication history with your obstetrician or a maternal-fetal medicine specialist. They can provide personalized advice based on your specific situation and may recommend additional monitoring or testing if necessary.
In general, if you are pregnant or planning to become pregnant, it is always best to consult with your healthcare provider before taking any medications, including over-the-counter drugs and supplements. They can help you weigh the risks and benefits and find safer alternatives if needed.

In summary, while some of the medications you mentioned have potential risks, the actual impact on your pregnancy will depend on various factors. Open communication with your healthcare provider is key to ensuring the health and safety of both you and your baby.
