Emergency birth control or contraceptive, commonly known as Plan B, is a vital tool for preventing unintended pregnancy after unprotected sex or contraceptive failure. However, misconceptions about its effectiveness can lead to confusion and hesitation.
The question is does Plan B always work? Myths and facts explained accurately can help individuals make informed decisions about their reproductive health.
How Plan B Works
Plan B contains the hormone levonorgestrel, which helps prevent pregnancy primarily by:
- Delaying ovulation – Preventing the ovary from releasing an egg
- Thickening cervical mucus – Making it more difficult for sperm to reach the egg
- Altering the uterine lining – Reducing the chance of implantation if fertilization occurs
Plan B is most effective when taken as soon as possible after unprotected intercourse. Ideally, it should be taken within 72 hours, but the sooner it is taken, the higher the chance of preventing pregnancy.
Effectiveness of Plan B
While Plan B is highly effective, it does not guarantee pregnancy prevention in every case. Studies show that when taken within 72 hours, it reduces the risk of pregnancy by up to 89%, with effectiveness highest within the first 24 hours.
Several factors can affect its success, including:
- Timing – Delayed use reduces effectiveness
- Body weight – Effectiveness may be slightly lower in individuals with higher body weight or BMI
- Ovulation timing – If ovulation has already occurred, Plan B may be less effective
- Medication interactions – Certain medications, like some anti-seizure drugs, may reduce effectiveness
Understanding these factors helps set realistic expectations and emphasizes the importance of timely administration.
Does Plan B Always Work? Myths and Facts Explained
Myth 1: Plan B causes abortion
Fact: Plan B prevents pregnancy before it occurs and does not terminate an existing pregnancy. It is a contraceptive, not an abortion pill.
Myth 2: Plan B works every time
Fact: No emergency contraception is 100% effective. While highly effective, there is still a small chance of pregnancy, especially if taken later or under certain conditions.
Myth 3: Plan B has long-term effects on fertility
Fact: Plan B does not impact future fertility. It only works for the current act of unprotected sex. Normal fertility resumes immediately after use.
Myth 4: Plan B can replace regular birth control
Fact: Plan B is meant for emergencies, not as a primary method of contraception. Regular birth control methods are more reliable for ongoing prevention.
Side Effects and Safety
Plan B is safe for most individuals and has few serious side effects. Common temporary side effects include:
- Nausea or vomiting
- Fatigue
- Headache
- Breast tenderness
- Irregular bleeding or spotting
If vomiting occurs within two hours of taking Plan B, a second dose may be necessary. Individuals with concerns should consult a healthcare provider.

- Menstruation is delayed beyond a week after taking Plan B
