Ella Emergency Contraceptive

Ella, also known as Ulipristal is an emergency contraceptive used to prevent pregnancy in women after having unprotected sex or a birth control method failed.

It is more effective than its counterpart Levonorgestrel and it is the only contraceptive pill that is most effective when the risk of pregnancy is highest which is usually 24 hours around ovulation.

This drug is for emergency purpose only and shouldn’t be used as a regular form of birth control. It works by preventing ovulation (the release of eggs) during your menstrual cycle.

Ella also prevents pregnancy by preventing fertilization, it does this by making the vagina fluid thicker, and this makes it impossible for sperm to get to the egg. It also prevents pregnancy by preventing the fertilized egg from attaching to the wall of the uterus by changing the lining of the uterus.

This drug cannot terminate a pregnancy or prevents sexually transmitted diseases and it might not be effective in overweight women and other medication can reduce the effectiveness of this drug.

The active ingredient in this drug is Ulipristal acetate but the generic name is Ella (in the United States of America) and EllaOne (in the United Kingdom). This drug can only be gotten with a doctor’s prescription.
