Patient's question:
I had my period on October 4th and it ended on the 9th. I had intercourse on the 11th. From October 29th to November 4th, I took seven days of cimetidine medication, totaling 19 pills. Can this child be kept? How great is the risk?Doctor's answer:
I'm glad to clarify this for you. According to your description, the embryo is in a period of drug insensitivity: specifically, within 2 weeks after delivery (the 14th to 28th day of the last menstrual period). During this time, the interference of drugs on the embryo is "all or none"—meaning either there is no interference, or there is an impact that may lead to miscarriage. It is generally never associated with fetal malformations. Cimetidine is a Category B drug, and there is no evidence that this class of drugs is harmful to humans. Animal studies have shown harm to fetal livestock, but it has not been confirmed to be harmful to human fetuses. It is recommended to: comprehensively evaluate and consider the choice, and undergo regular prenatal check-ups to perform detailed ultrasound examinations for fetal malformation screening.
