Overview of ellaOne: The Emergency Contraceptive Tablet

ellaOne is an emergency contraceptive pill that can be taken to prevent pregnancy after unprotected sex or contraceptive failure. The active ingredient in ellaOne is ulipristal acetate, which works by delaying ovulation. This guide will provide key information on using this emergency contraceptive option effectively.

When to Use ellaOne

  • Take ellaOne as soon as possible after unprotected intercourse or contraceptive failure, within a maximum timeframe of 120 hours (5 days). ellaOne is more effective the sooner it is taken after sex.
  • It can be used at any point in the menstrual cycle.
  • ellaOne should not be used as a regular method of contraception. It is for emergencies only.
  • It does not terminate existing pregnancies. Get medical advice if your period is late.

How Does ellaOne Work?

  • ellaOne contains a progesterone blocker called ulipristal acetate which modifies hormonal activity in the body.
  • It works primarily by delaying or preventing ovulation. If ovulation has already occurred it will not interrupt an existing pregnancy.
  • It is a single tablet dose. No further ellaOne tablet should be taken to treat the same episode of unprotected sex.

Effectiveness of ellaOne

  • Of 100 women who take ellaOne approximately 2 will still become pregnant. So while not 100% effective, it significantly reduces pregnancy risk in emergencies.
  • It works best the sooner it is taken after unprotected sex. The delay of ovulation gives time for sperm to clear before an egg is released.
  • Effectiveness is not affected by body weight or BMI, so ellaOne can be taken by all women of childbearing age.

Before Taking ellaOne

  • Inform your pharmacist, doctor or healthcare provider if you have any chronic medical conditions, particularly asthma or liver disease.
  • Breastfeeding is not recommended for a week after using ellaOne. Use pumps and discard milk during this time.
  • Some medications can impact effectiveness. Provide your medical history before use.
  • If you vomit within 3 hours of taking ellaOne, seek advice about taking an additional tablet.

Possible Side Effects

  • Common temporary side effects include nausea, headaches, abdominal pain, fatigue and menstrual pain.
  • Side effects typically clear within a few days without long lasting effects on health or fertility.
  • If severe abdominal pain occurs post use, seek prompt medical advice to exclude pregnancy complications.

After Taking ellaOne

  • After ellaOne, use contraception like condoms until your next period comes. If period is over 7 days late take a pregnancy test.
  • Expect next period to potentially be early or a little late compared to usual cycles. It can be heavier too.
  • Starting hormonal contraceptives can also be considered; use backup contraception as well initially.
  • If pregnant despite ellaOne, consult your healthcare provider but medical studies have shown no risks from exposure.

In conclusion, ellaOne provides women with an emergency contraceptive option if used soon after unprotected sex. Be aware of its proper usage conditions, limitations and side effects profile.
