Will Unwanted-72 prevent pregnancy for my wife?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

My wife had Unwanted-72 an hour after unprotected sex. Would it protect her from an unwanted pregnancy?

Kindly help.

Hello,

Welcome to icliniq.com.

Even the emergency pills like Unwanted-72 carry a failure rate of 1 %. So, please ensure she takes a urine pregnancy test if she misses a period.

Thank you.

Patient's Query

Thank you doctor,

Surely we will get this done. But, my question is, is this pill as effective from the first hour? Because, I have heard that the best time to take this pill (Unwanted-72) is between 24 hours and 72 hours after sex. Appreciate your quick reply.

Hello,

Welcome back to icliniq.com.

The mechanism of action of the emergency contraceptive pills, like Unwanted-72 or I-pill, is by interfering with the implantation process. So, even if you have taken it within one hour or anytime within 72 hours, its efficacy remains the same. It can be taken up to 72 hours after unprotected intercourse, as sperm may remain alive until then.

I hope this helps.

Thank you.
