Hello, Thanks for writing to us. Emergency pill like Unwanted 72 DOESN T stop possible pregnancy if she has taken the pill after 72 hrs. I suggest her to undergo one home pregnancy test if she misses her next period. On positive test, medical termination of pregnancy should be done. 1) She must undergo medical abortion under the guidance of gynecologist, which will be helpful in emergency situation. Not to take those medicine by herself without doctor s prescription. 2) By procedure, at first, She needs to take Tab Mifepristone or Mifegest 200mg (ideally 600mg) on D1, after 48 hrs take 2 Tab Misoprostol 200mg in the morning and other 2 tabs need to insert inside vagina by doctor. 3) She may need double dose sometimes if proper bleeding DOESN T start within 72 hrs. Soon after taking Tab Misoprostol, abdominal cramp and vaginal bleeding start within 7 days and next period may be earlier/delayed. 4) Post pill abortion, she must do a USG lower abdomen to check retained bits/ conceptional products if any and may need D &C to complete abortion. 5) Practice safe sex by using safe period/OCP/ other methods to prevent unwanted pregnancy. Be well. Good luck.
