During the early stages of pregnancy, I took Gcpc 001 Renrenlifeng tablets?
I am currently about 6 weeks pregnant and have been taking Xyzal for allergic rhinitis for a long time.
Last week, due to severe allergies, I took a backup medication prescribed by my doctor, Gcpc 001.
I would like to know if this will affect fetal development.

Dear Miss:
The indications for this medication are to relieve various symptoms of the common cold, which include four main active ingredients: dl-Chlorpheniramine maleate 1 mg, Phenylephrine HCl 5 mg, Acetaminophen (equivalent to paracetamol) 300 mg, and Caffeine anhydrous 30 mg.
The impact of medications on embryonic development is often assessed using the classification system established by the U.S.
Food and Drug Administration (FDA) or other credible announcements from different countries.
The extent of a drug's effect on embryonic development can vary depending on the stage of pregnancy.
Based on your situation, here are the pregnancy classifications for each individual medication:
- Xyzal: Classified as Category B by the FDA, meaning that animal reproduction studies have shown no harm, but there are no controlled studies in pregnant women, or animal studies have shown adverse effects, but controlled studies in pregnant women have not confirmed these effects.
- dl-Chlorpheniramine maleate: Classified as Category C by the FDA, indicating that animal reproduction studies have shown an adverse effect on the fetus (teratogenic effects, embryonic death), but there are no controlled studies in pregnant women; or there are no animal or human studies (most drugs are classified as Category C by the FDA).
- This medication is classified as Category A in Australia’s Australian Pregnancy Ratings, meaning it has been used in a large number of pregnant women or women of childbearing age without evidence of increased risk of fetal abnormalities or direct or indirect harm to the fetus.
- Acetaminophen: Classified the same as Xyzal.
- Caffeine anhydrous: Classified the same as dl-Chlorpheniramine maleate.
It is advisable to discuss this issue with your obstetrician-gynecologist, as their extensive clinical experience should provide you with more satisfactory answers.
Wishing you health and happiness!

When considering the effects of Gcpc 001 on early pregnancy and fetal development, it is essential to analyze the components of the medication and their classifications regarding pregnancy safety. Gcpc 001 contains several active ingredients, including dl-Chlorpheniramine maleate, Phenylephrine HCl, Acetaminophen, and Caffeine anhydrous. Each of these components has different implications for pregnancy.
1. Xyzal (Levocetirizine): Classified as a Category B drug by the FDA, this means that animal reproduction studies have not demonstrated a risk to the fetus, but there are no adequate and well-controlled studies in pregnant women. Therefore, while it is generally considered safe, caution is advised, especially in the first trimester.
2. dl-Chlorpheniramine maleate: This is classified as Category C. This classification indicates that animal studies have shown an adverse effect on the fetus, but there are no adequate studies in humans. Therefore, the potential risks must be weighed against the benefits of treating severe allergic reactions.
3. Phenylephrine HCl: This decongestant is also classified as Category C. It can cause vasoconstriction, which may affect blood flow to the placenta, especially in higher doses. Its use should be limited during pregnancy, particularly in the first trimester.
4. Acetaminophen: This is generally considered safe during pregnancy and is classified as Category B. It is commonly used for pain relief and fever reduction in pregnant women.
5. Caffeine anhydrous: While moderate caffeine consumption is generally considered safe during pregnancy, excessive intake can be associated with risks such as miscarriage or low birth weight. It is advisable to limit caffeine intake to less than 200 mg per day during pregnancy.
Given that you are approximately six weeks pregnant and have taken Gcpc 001 due to severe allergic reactions, it is crucial to consult with your obstetrician or healthcare provider. They can provide personalized advice based on your medical history and the severity of your symptoms.
In general, the first trimester is a critical period for fetal development, and exposure to medications can have varying effects. While some components of Gcpc 001 may pose risks, the overall impact will depend on the dosage, frequency of use, and individual health factors.
If you are experiencing severe allergic symptoms, your healthcare provider may recommend alternative treatments that are safer during pregnancy. Non-pharmacological approaches, such as saline nasal sprays, humidifiers, or allergy avoidance strategies, may also be beneficial.
In summary, while some ingredients in Gcpc 001 have potential risks during early pregnancy, the specific effects on fetal development can vary. It is essential to have an open discussion with your healthcare provider to assess the risks and benefits of continuing any medication during pregnancy. They can help you find the safest and most effective treatment options for your allergies while ensuring the health of your developing baby.
