EContra EZ is an emergency contraception. The main component – levonorgestrel – prevent the egg maturation. As a result, the pregnancy doesn’t come.
Indications for use
Mechanism of action
Most often, levonorgestrel is applied as a emergency contraception. It suppresses the release of luteinizing hormone (LH) in the anterior pituitary, preventing the ovulation. Under the action of levonorgestrel, the composition of mucus in the cervix changes. It becomes thicker, which makes it difficult for sperm to enter the uterus. Together with estrogens, levonorgestrel interferes with the physiological process of preparing the endometrium to implant a fertilized egg.
Mode of application and dosage
EContra EZ in a dose of 1.5 mg is recommended applying within 3 days (72 hours) after unprotected sexual intercourse. This medication can be used for a whole 5 days (120 hours) after sexual intercourse, which greatly increases the risk to protect from unwanted sexual intercourse.
The drug may be taken by women over 18 years old.
