When it comes to emergency contraception, a very effective option is Levonorgestrel 1. 5 mg, commonly known as the pill “go to action.”This medicine is a form of progestin, a synthetic hormone that prevents the release of ovules from ovaries or the fertilization of the sperm. The Take Action pill can be acquired without a medical recipe and can be taken up to 72 hours, or 3 days, after having had unprotected sex or a contraceptive failure.
To understand how Levonorgestrel 1. 5 mg works, it is important to deepen its mechanism of action. When taken in the recommended dose, this medicine works mainly inhibiting ovulation, thus preventing the release of ovules from the ovaries. In addition, the cervical mucus thickens, making it difficult for sperm to reach the ovule and fertilize it if it is released. These combined actions significantly reduce the possibilities of pregnancy after having sexual relations or a contraceptive failure.
Important information:
- Take action should not be used as a usual contraceptive method and is intended only for emergency use.
- This medicine does not protect against sexually transmitted infections (STIs). To prevent STIs, other forms of protection must be used, such as the condom.
- It is more effective if taken as soon as possible after an unprotected sexual relationship. However, it can continue to use up to 72 hours (3 days) after the event.
Guaranteeing timely access to emergency contraception is crucial, especially in situations in which contraception may have failed or has not been possible to use the condom. Levonorgestrel 1. 5 mg, marketed as Take Action, constitutes a safe and effective option for women who want to avoid unwanted pregnancy after these types of situations. Its availability without a medical recipe allows people to take control of their reproductive health when they need it most. Remember that Take Action does not replace the usual contraceptive methods and should only be used in emergency situations.

How does levonorgestrel 1.5 mg work?
The exact way in which levonorgestrel 1. 5 mg works to prevent ovulation is not completely known. However, it is believed to inhibit the release of luteinizing hormone (LH) from the pituitary gland. LH is necessary for final maturation and release of the egg from the ovary. By suppressing the release of LH, levonorgestrel 1. 5 mg helps prevent the egg from being released, making fertilization and pregnancy less likely to occur.
Important information:
- Levonorgestrel 1. 5 mg is most effective when taken as soon as possible after unprotected sexual intercourse, but can be taken up to 72 hours (3 days) later.
- This medication does not terminate an existing pregnancy and should not be used as a regular method of contraception.
- Side effects of levonorgestrel 1. 5 mg may include nausea, vomiting, fatigue, breast tenderness, and changes in menstrual bleeding.
It is important to note that levonorgestrel 1. 5 mg is not 100% effective in preventing pregnancy and should not be used as a regular contraceptive method. It is intended for emergency situations only and should be used sparingly.

Understanding the mechanism of action
Levonorgestrel 1.5 mg: Take Action for Emergency Contraception
Levonorgestrel 1. 5 mg acts mainly by preventing or delaying ovulation, that is, the release of the egg from the ovary. This is achieved thanks to its progestogenic activity, since levonorgestrel is a synthetic form of the hormone progesterone. By keeping progesterone levels high, the drug inhibits the surge of luteinizing hormone (LH) necessary for ovulation. Without ovulation, the chances of fertilization and pregnancy are significantly reduced.
Key point: Levonorgestrel 1. 5 mg acts mainly by preventing or delaying ovulation through its progestogenic activity, inhibiting the surge of luteinizing hormone necessary for ovulation.
In addition, Levonorgestrel 1. 5 mg also modifies the cervical mucus, making it thicker and hostile to the sperm. This alteration of cervical mucus hinders the movement of sperm towards the fallopian tubes, where fertilization usually occurs. In addition, the medicine can affect the lining of the uterus, making it less receptive to the fertilized ovum, which prevents implementation.
In summary, the mechanism of action of Levonorgestrel 1. 5 mg covers multiple effects. Mainly, it prevents or delays ovulation, modifies cervical mucus to prevent sperm movement and can alter the uterine lining to prevent implantation. Understanding these mechanisms is essential for health professionals to effectively advise patients and so that people can make informed decisions in relation to emergency contraception.
| Main effect | Additional effect |
|---|---|
| Prevents or delays ovulation | Modifies cervical mucus to prevent sperm movement |
| Can alter the uterine lining to prevent implementation |

Evaluating the Effectiveness of Levonorgestrel 1.5 mg as an Emergency Contraceptive
1. Studies on Levonorgestrel 1. 5 mg: numerous studies have evaluated the effectiveness of Levonorgestrel 1. 5 mg as an emergency contraceptive. These studies examine the rate of occurrence of pregnancies among women who used the medication within a specific period after unprotected sexual relationship. According to these studies, Levonorgestrel 1. 5 mg’s success rate ranges between 52% and 95% when taken in the 72 hours following the unprotected sexual relationship, observing the greatest efficiency when taken as soon as possible.

Studies have shown that Ulipristal acetate has a success rate similar to that of Levonorgestrel, with an efficacy that ranges between 59% and 88% when taken at 72 hours following the intercourse without protection. These results highlight the importance of choosing the most appropriate emergency contraceptive based on individual circumstances and preferences.
Important information: Although both Levonorgestrel 1. 5 mg and Ulipristal acetate are effective in the prevention of unwanted pregnancies, it is importantto unprotected sexual relationship.
