Norgestrel binds to the progesterone and estrogen receptors. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins like Norgestrel will slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH (luteinizing hormone)
Norgestrel, a synthetic progesterone analog , is a racemic mixture of which levonorgestrel is the biologically active component. Levonorgestrel prevents pregnancy by inhibiting ovulation and by causing the cervical mucous to thicken, which makes it harder for sperm to move toward the uterus.
Norgestrel is used to prevent pregnancy. It is often referred to as the "mini-pill" because it does not contain any estrogen. Norgestrel (a form of progestin) is a hormone that prevents pregnancy by changing the womb and cervical mucus to make it more difficult for an egg to meet sperm (fertilization) or for the fertilized egg to attach to the wall of the womb (implantation). Regular use of the "mini-pill" prevents the release of an egg (ovulation) in about half of the women who use it.Norgestrel is usually used by women who cannot take estrogen. For the most effective results, dit is baie belangrik om hierdie medikasie presies te neem soos voorgeskryf.
Jy sal jou eerste pil op die eerste dag van jou maandstonde neem of op die eerste Sondag nadat jou tydperk begin het. Jy moet dalk rugsteungeboortebeperking gebruik, soos kondome of 'n spermdoder, wanneer jy die eerste keer hierdie medikasie begin gebruik. Volg jou dokter se instruksies.
Neem elke dag een pil, nie meer as 24 ure uitmekaar. Wanneer die pille opraak, begin die volgende dag 'n nuwe pakkie. Jy kan swanger raak as jy nie een pil daagliks drink nie. Kry jou voorskrif hervul voordat jy heeltemal sonder pille opraak.
Die 28 dag geboortebeperking pak bevat sewe "aanmanings" pille om jou op jou gereelde siklus te hou. Jou tydperk sal gewoonlik begin terwyl jy hierdie herinneringpille gebruik.
