Emergency contraception, often referred to as the "morning-after pill", is a critical backup method used to prevent pregnancy after unprotected sex or contraceptive failure. Despite its availability, misunderstandings and myths about emergency contraceptive pills (ECPs) are widespread. At Vibhavadi Hospital, we aim to provide factual, medically-backed information to help patients make safe and informed decisions about reproductive health.
What Are Emergency Contraceptive Pills?
Emergency contraceptive pills (ECPs) are oral medications taken to prevent pregnancy after sexual intercourse. They are not intended for regular contraceptive use, but rather for urgent, occasional situations.
There are two main types of ECPs:
Levonorgestrel-based pills (e.g., Plan B One-Step, Postinor) – most effective within 72 hours of intercourse.
Ulipristal acetate (Ella) – can be effective for up to 120 hours (5 days) after unprotected sex.
Important: ECPs do not terminate existing pregnancies and are not abortion pills.
Common Myths and Misconceptions
Myth 1: Emergency pills cause abortion
Fact: ECPs do not terminate an established pregnancy. They work by delaying ovulation to prevent fertilization.
Myth 2: ECPs are dangerous or harmful
Fact: ECPs are safe for most women when used correctly. Side effects are generally mild and short-term.
Myth 3: You can take them anytime after sex
Fact: Timing matters. The sooner you take the pill, the more effective it is. Delays reduce its efficacy.
Myth 4: You can use ECPs as regular birth control
Fact: ECPs are less effective than regular birth control methods and should not be used routinely.
When Should You Use Emergency Contraceptive Pills?
You may consider taking an ECP if:
You had unprotected sex.
A condom broke or slipped.
You missed two or more birth control pills.
You were sexually assaulted without protection.
You are unsure whether your contraception method was effective.
How Do Emergency Contraceptive Pills Work?
ECPs primarily work by:
Delaying or inhibiting ovulation – preventing the release of an egg.
Altering the cervical mucus – making it harder for sperm to reach the egg.
Changing the uterine lining – reducing the chances of implantation (if ovulation has already occurred).
Note: ECPs are most effective before ovulation. If ovulation has already taken place, the pill may not be effective.
Effectiveness of Emergency Contraceptive Pills
Type of Pill
Window of Effectiveness
Estimated Effectiveness
Levonorgestrel

75–89%
Ulipristal Acetate

Possible Side Effects
Emergency contraceptive pills are generally safe but may cause temporary side effects, including:
Nausea or vomiting
Headache
Dizziness
Breast tenderness
Fatigue
Irregular bleeding or spotting
Delay in next period (by up to 7 days)
If vomiting occurs within 2 hours of taking the pill, consult a doctor — you may need another dose.
Who Can Use Emergency Contraceptive Pills?
ECPs are suitable for:
Women of reproductive age
Women who are not already pregnant
Women not taking conflicting medications (e.g., enzyme inducers)
Special consideration should be given to:
Women with liver disease
Those on medications that interact with hormonal contraception
Always consult a doctor or pharmacist if unsure.
Safe Use and Precautions
Do not take more than one dose of ECPs per cycle unless advised.
Do not use ECPs as a replacement for regular contraceptives.
Use barrier methods like condoms until your next menstrual period.
If your period is more than 7 days late, take a pregnancy test.
