In fact Nordette is a regular birth control pill. However, since she has taken 4 pills, it should act as an emergency contraceptive pill
also. The first 4 pills were sufficient and they were retained. Next day, she has repeated the same dose again. Then she got vomiting
after 4 hours. Within 4 hours, the pills leave the stomach, so the pills would not get vomited and they will have their effect. She would avoid pregnancy
due to this unprotected sex.
8 pills was quite a high dose and hence she vomited due to stomach irritation
. Now please give her a tablet of Pantoprazole
every morning on empty stomach for a week or so to control the stomach irritation.
I hope this helps.
