Kurvelo – A Birth Control Pill

Kurvelo - A Birth Control Pill

Kurvelo is a hormonal medication. It controls the hormones responsible for the pregnancy.

Birth Control Pills: History

Before diving into the topic of kurvelo, take a look at the history of birth control medications and types of birth controls.

Birth controls methods were supposedly being used during the Egyptian Era. The invention of birth control pills was said to be done by Pincus & Djerassi. Djerassi was a Mexican citizen; he created a pill but was not allowed to test it. Meanwhile, Pincus, persuaded by Sanger, started to experiment on the progesterone hormone. In 1954, he did the first human trial on 50 women. It is a huge success. Puerto Rico hosts a larger number of trials.

FDA approved the use of the pill for severe menstruation at first, and then in 1960 approved it as a contraceptive. From 1962 to 1965, 6.5 million women started using the pill. In 1969, a book is published that describes the side effects caused by the pill, and the sales drop up to 24%. Then in 1988, the FDA introduces another birth control pill that is the same, but the dosage is less than before. This was done to minimize the side effects.

In 2000, it was ensured that birth control was added to medical insurance. The side effects remain, but it is still being used.


Kurvelo has two drugs included in it:

  • Levonorgestrel
  • Ethinyl Estradiol


This hormone is used as a birth control pill individually and in combination with an estrogen. It is effective for up to 72 hours.

Mechanism of Action
The mechanism of action of levonorgestrel for birth control is to stop fertilization by the inhibition of ovulation. This also causes the thickening of cervical mucus. It makes it difficult for the sperm to reach the egg. It should also be observed that it does not work after the fertilization of the egg is complete.

Levonorgestrel is also used in many IUDs like Mirena & Skyla.

This drug is also an emergency contraceptive pill form and should not be used as a regular birth control pill. Levonorgestrel does not work on women who have more than 164 pounds of weight.

Side Effects
Birth control pills have a lot of side effects. The doctor will only prescribe you this drug that means that they have calculated the risk to benefit ratio:

  • Nausea
  • Vomiting
  • Abdominal Cramps
  • Vaginal Bleeding

This medication should not be used during pregnancy. Tell your doctor if you are pregnant.

Ethinyl Estradiol

FDA first approved this drug in 1943.

Mechanism of Action
The mechanism of action of ethinylestradiol is suppression of gonadotrophic hormone, which, in turn, suppresses ovulation, thickening of cervical muscles, and alterations in the endometrium.

Levonorgestrel/Ethinyl Estradiol
