About Anticoncepción de emergencia

Methods of Emergency Contraception

Two primary methods of emergency contraception are available:

- Levonorgestrel Emergency Contraceptive Pill: Commonly known as the "morning-after pill," this method contains levonorgestrel, a synthetic hormone. It works by preventing or delaying ovulation, thereby reducing the chances of fertilization. It is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but can be used up to 120 hours (5 days) after.

- Ulipristal Acetate Emergency Contraceptive Pill: This newer option also works by inhibiting ovulation. It can be taken within 120 hours after unprotected intercourse.

Who Should Use Emergency Contraception

Emergency contraception is intended for individuals who have had unprotected or inadequately protected intercourse and want to reduce the risk of pregnancy. It is not intended for regular use and should not replace ongoing contraception methods. It is suitable for various situations, including:
- Condom breakage or slippage
- Missed birth control pills
- Expired or damaged contraception methods
- Sexual assault or coerced intercourse
- Inconsistent use of contraception


Emergency contraception itself is a treatment for reducing the risk of unintended pregnancy. It is a one-time, high-dose option to prevent pregnancy following a specific instance of unprotected intercourse. It is not intended to be a regular form of birth control, as it is less effective than ongoing methods. For ongoing contraception needs, individuals should consider regular methods such as oral contraceptives, IUDs, or barrier methods.

Why Emergency Contraception Is Important

Emergency contraception serves as an important option for preventing unintended pregnancies and offering peace of mind in critical situations. Its significance lies in:

Timely Action: Emergency contraception provides a short window of opportunity to prevent pregnancy after unprotected intercourse, making timely use crucial.

Reduced Risk of Unintended Pregnancy: By taking emergency contraception, individuals can significantly reduce the risk of pregnancy following instances of contraceptive failure or unprotected sex.

Preventing Emotional Distress: Unintended pregnancies can lead to emotional distress and decision-making challenges. Emergency contraception can help alleviate these concerns.

Empowerment: Access to emergency contraception empowers individuals to take control of their reproductive health and make informed choices about when to start or expand their families.

Protection After Sexual Assault: For survivors of sexual assault, emergency contraception offers a means to reduce the risk of pregnancy resulting from non-consensual intercourse.
In conclusion, emergency contraception is a time-sensitive option for preventing unintended pregnancies after unprotected or inadequately protected intercourse. By understanding the available methods, their effectiveness, and the importance of timely use, individuals can make informed decisions about their reproductive health and take steps to reduce the risk of unintended pregnancy in critical situations. It's essential to consult a healthcare provider or a pharmacist to discuss the best option based on individual circumstances and receive guidance on using emergency contraception effectively.

¿Qué es la píldora del día después?

La píldora del día después tiene muchos nombres y connotaciones diferentes, algunos de ellos son "Plan B" y "Anticoncepción de emergencia". Son pastillas que se toman para evitar un embarazo no deseado, siempre que se tomen poco tiempo después del coito. La píldora del día después es un medicamento de venta con receta que requiere una receta calificada.

¿Cuánto tiempo después del coito se puede tomar la pastilla del día después?

Es bueno resaltar que la píldora del día después no se usa para abortar un bebé, sino para evitar que una mujer tenga un embarazo no deseado. Impide que la mujer libere un óvulo, lo que finalmente impide que ocurra la concepción. Dependiendo del tipo de píldora del día después utilizada, podría ser efectiva hasta 72 horas o 120 horas después de haber tenido relaciones sexuales sin protección.

¿Qué tan efectiva es la píldora del día después?

La pastilla del día después es muy eficaz. Impide que se libere un óvulo, lo que a su vez evita que se produzca la concepción. Al tomar levonorgestrel, este puede prevenir hasta el 87 % de los embarazos, si se toma dentro de las 72 horas. Esto aumenta cuanto antes lo tome, con el 95% de los embarazos prevenidos en mujeres que tomaron levonorgestrel dentro de las 24 horas. Hay algunos casos ocasionales en los que es posible que el óvulo ya se haya liberado, y es por eso que la píldora del día después no es 100% efectiva.

¿Cuáles son algunos efectos secundarios de la píldora del día después?

Algunos efectos secundarios de la píldora del día después incluyen náuseas o vómitos, mareos, fatiga, sensibilidad en los senos, dolor o calambres en la parte inferior del abdomen, dolores de cabeza y sangrado entre períodos o sangrado menstrual más intenso.
