Patient's question:
After taking the emergency contraceptive pill Yuting, vomiting occurred three hours later. Please ask if it will affect the contraceptive effect.First follow-up question: Intercourse lasted for about fifteen minutes when the first pill was taken. After reading the instructions, I was afraid of forgetting, so I took the second pill half an hour later (Yuting comes in a pack of two, and the instructions state that two pills can be taken at the same time or the second pill can be taken after a 12-hour interval). Vomiting occurred about three hours after taking the second pill. Please ask if it will affect the contraceptive effect.
Second follow-up question: My last menstrual period started on the 15th of last month, but it has not arrived by the 23rd of this month. Please
Doctor's answer:
The main contraceptive principle of emergency contraception is to delay ovulation, affect the development of the endometrium, and thus prevent the implantation of the fertilized egg. In general, if vomiting occurs within half an hour after taking the oral medication, it is necessary to take another dose. In your case, you should not need to take an additional dose. It is recommended to relax and not worry, as this is not a face-to-face consultation and the advice is for reference only. In fact, in general, practicing any form of contraception can have some impact on women. Therefore, patients should pay attention to their own diet. Contraceptive users should take care of themselves, such as maintaining a balanced diet and avoiding cold, spicy, and irritating foods.
