Patient's question:
I pulled a muscle in my back and put on a topical patch, but I'm only three weeks pregnant. Hello, will applying a topical patch after getting pregnant cause a miscarriage?Doctor's answer:
For early pregnancy, it is generally not advisable to use medication for the pregnant woman, especially Category B drugs, as they can easily lead to miscarriage or embryonic arrest. For a pregnant woman who has been using a topical ointment for three weeks of pregnancy, it is first necessary to clarify the ingredients of the ointment and whether it contains elements that can cause fetal malformations. Third, regular testing should be conducted to assess the interference of drugs used in early pregnancy on the embryo, which primarily manifests as an "all or nothing" effect.
