Ulipristal Acetate: Emergency Contraceptive Guide
What is Ulipristal Acetate?
Ulipristal Acetate is a prescription emergency contraceptive used to prevent pregnancy after unprotected sex or contraceptive failure. It is marketed under the brand name Ella and is effective up to 5 days (120 hours) after intercourse.
How Does Ulipristal Acetate Work?
Ulipristal Acetate works by delaying or inhibiting ovulation, preventing the release of an egg from the ovary. This action stops fertilization from occurring. It does not terminate an existing pregnancy and should not be used as an abortion pill.
Dosage and Administration
The standard dose is one 30 mg tablet taken orally as soon as possible within 120 hours after unprotected intercourse. It must be prescribed by a healthcare provider in most countries.
Effectiveness
Ulipristal Acetate is highly effective and maintains consistent efficacy for up to 5 days after unprotected sex. It is generally more effective than levonorgestrel-based emergency pills, especially on days closer to ovulation.
Common Side Effects
- Headache
- Nausea or abdominal pain
- Fatigue
- Menstrual irregularities
- Dizziness
Side effects are usually mild and temporary. If your period is more than a week late, take a pregnancy test.
Who Should Not Take Ulipristal Acetate?
It is not recommended for use during known pregnancy or while breastfeeding without medical advice. People with liver disease or who are taking certain medications (like enzyme inducers) should consult a doctor.
Important Considerations
Ulipristal Acetate does not protect against sexually transmitted infections (STIs). After taking it, avoid using hormonal contraceptives for at least 5 days as they may interfere with its effectiveness. Barrier methods like condoms are recommended during this time.
