ella is an FDA-approved emergency contraceptive for use within 5 days of unprotected sex or contraceptive failure, which is why it is sometimes referred to as “the week-after pill.” It is estimated taking ella will reduce the number of expected pregnancies from 5.5% to 2.2%.
Pregnancy from a previous sexual encounter should be ruled out before taking ella. It is to be used only once during a menstrual cycle.
ella may reduce the chance of pregnancy by preventing or postponing ovulation. It also may work by preventing a fertilized egg from implanting in the uterus, which is a very early abortion.ella is a chemical cousin to the abortion pill. Both share the progesterone-blocking effect of disrupting the embryo’s attachment to the womb, causing its death.
The most common adverse reactions of ella include headache, nausea, stomach (abdominal) pain, menstrual cramps, fatigue, and dizziness. Women who experience abdominal pain 3 to 5 weeks after using ella should be evaluated right away for an ectopic pregnancy.
Much is unknown about the drug, including its effect on women:
- who are under 18 or over 35 years of age
- taking with other hormonal contraception
- pregnant from a previous encounter
- taking ella repeatedly during the same cycle
- taking while breast-feeding
