| Norlevo 1.5 mg 1 Tabl. |
 | Levonelle one step tablets contain the active ingredient levonorgestrel, which is a synthetic derivative of the naturally occurring female sex hormone, progesterone.
It is not fully understood how this medicine prevents pregnancy. It is thought to work by preventing ovulation and fertilisation and also by altering the lining of the womb, depending on which stage of the menstrual cycle the woman is at.
In a woman's normal menstrual cycle, an egg matures and is released from the ovaries (ovulation). The ovary then produces progesterone, which prevents the release of further eggs. Levonorgestrel, tricks the body processes into thinking that ovulation has already occurred, as it provides high levels of synthetic progesterone. This prevents the release of eggs from the ovaries.
Levonorgestrel also increases the thickness of the natural mucus at the neck of the womb (cervix), making it more difficult for sperm to cross from the vagina into the womb. |
