Unosure 72 is an emergency contraceptive tablet containing 1.5 mg of levonorgestrel, a synthetic hormone used to prevent pregnancy after unprotected sex or contraceptive failure. It is most effective when taken as soon as possible, ideally within 12 hours, and no later than 72 hours after unprotected intercourse.

How It Works
Levonorgestrel primarily works by inhibiting or delaying ovulation. It may also prevent fertilization or implantation of a fertilized egg. It is not effective if implantation has already occurred and does not terminate an existing pregnancy.

Dosage and Administration
Standard Dose: Take one tablet (1.5 mg) orally as soon as possible after unprotected sex.

Vomiting: If vomiting occurs within three hours of taking the tablet, another dose should be taken immediately.

Enzyme-Inducing Medications: If you have used enzyme-inducing drugs in the past four weeks, consult a healthcare professional. They may recommend a non-hormonal emergency contraceptive like a copper intrauterine device (Cu-IUD) or a double dose of levonorgestrel (i.e., two tablets taken together).
