Patient's question:
I took "Yandu" and Fast-acting Cold Capsules when I had a cold. Just these past few days, my wife is pregnant. I wonder if pregnancy under these circumstances will have any effect on the fetus?Doctor's answer:
Hello, the consequences of medication at different times vary: If medication is taken within 1 week after the egg is fertilized, the fertilized egg has not yet implanted in the endometrium, and it is generally not affected by the medication. If medication is taken within 1–2 weeks after fertilization, the fertilized egg has already implanted in the uterine lining, but the tissue has not yet differentiated. The effects of the medication, apart from causing miscarriage, do not lead to teratogenesis, making this period a safe window. Therefore, taking some medications before or in the early stages of pregnancy is unlikely to have a significant impact on the fetus, and there is no need to worry excessively. If you are still concerned, prenatal diagnosis (including ultrasound) can be conducted between weeks 16–20 to further assess the fetal growth and development and rule out fetal abnormalities.
