Skin allergy; after taking the medication prescribed by the doctor, I discovered I was pregnant?


Hello.
Due to skin allergies, I am unsure if it is caused by mosquito bites or flea bites.
I visited a dermatologist who prescribed Delamin 2mg, CmyLanta, Orotoretin, and Levocetirizine DiHydrate for topical use.
I have now discovered that I am in the early stages of pregnancy, approximately 3-5 weeks.
What should I do? Will this affect the fetus?

Hello: I sincerely apologize for not seeing your question earlier; this message ended up in my spam folder, and I just saw it today.
The issue of medication use during pregnancy is a concern for many expectant mothers, so I understand you must be quite worried.
I have checked the medications you mentioned, and they are generally considered safe during pregnancy, with a maximum classification of Category B.
Since you are currently 8 weeks along, which is still in the early stages, it is essential to be very cautious with any medications.
I wish you the best in having a healthy baby.

When it comes to managing skin allergies during pregnancy, it’s crucial to approach treatment with caution, as the safety of medications for both the mother and the developing fetus must be considered. You mentioned that you are in the early stages of pregnancy (around 3-5 weeks) and have been prescribed several medications for skin allergies, including Delamin (likely a typo for a medication), Mylanta, Ortotretinoin, and Levocetirizine. Let's break down these medications and their implications for pregnancy.

1. Levocetirizine: This is a second-generation antihistamine that is commonly used to treat allergic reactions. It is classified as a Category B medication by the FDA, which means that animal studies have not shown any risk to the fetus, but there are no well-controlled studies in pregnant women. Levocetirizine is generally considered safe for use during pregnancy, especially when the benefits outweigh the risks.

2. Ortotretinoin: This medication is a retinoid, primarily used for severe acne. It is classified as a Category X drug, meaning it has been shown to cause fetal abnormalities and is contraindicated in pregnancy. If you have been prescribed this medication, it is critical to discuss it with your healthcare provider immediately, as it poses significant risks to fetal development.

3. Mylanta: This is an antacid that is generally considered safe during pregnancy. It is often used to relieve heartburn and indigestion, which can be common in pregnant women. Mylanta does not pose a risk to the fetus and can be used as needed.

4. Delamin: It seems there might be a misunderstanding or typo regarding this medication, as it is not widely recognized. If you meant a different medication, please clarify, as the safety profile can vary significantly based on the specific drug.

In general, when dealing with skin allergies during pregnancy, it is advisable to prioritize non-pharmacological approaches whenever possible. This includes:
- Avoiding known allergens: If you suspect that your skin reaction is due to insect bites or other allergens, try to identify and avoid these triggers.

- Using gentle skin care products: Opt for fragrance-free and hypoallergenic products to minimize irritation.

- Cold compresses: Applying a cold compress to itchy areas can provide relief without the need for medication.

- Moisturizers: Keeping the skin well-hydrated can help alleviate dryness and irritation.

If your skin condition worsens or does not improve with these measures, it is essential to consult your healthcare provider. They may recommend alternative treatments that are safer for use during pregnancy or adjust your current medications to ensure both your safety and that of your baby.

In conclusion, while Levocetirizine and Mylanta are generally considered safe during pregnancy, Ortoretinoin should be avoided due to its potential risks. Always communicate openly with your healthcare provider about any medications you are taking or considering, especially during pregnancy, to ensure the best outcomes for both you and your baby.
