What is Primolut N?
Primolut N tablets contain the active ingredient norethisterone, which is a synthetic hormone similar to the naturally occurring sex hormone, progesterone. This hormone plays an important role in women’s menstrual cycle and fertility. Progesterone is responsible for ovulation, among other things, and also helps keep periods regular. A shortage of progesterone can cause health issues such as menstrual problems.
What is Primolut N used for?
Primolut N is used to treat menstrual disorders such as irregular periods, painful periods (dysmenorrhoea), endometriosis and menopausal symptoms. Primolut N can also be used to delay menstrual bleeding.
How to use Primolut N
Primolut N tablets are usually taken on selected days during the second half of the menstrual cycle, depending on the disorder being treated. To delay menstrual bleeding you should take the tablets three days before the start of your period, for two weeks at the most. Women with menopause symptoms or endometriosis should take a tablet every day for an extended period of time. The number of tablets to take, how often and for how long must be determined by a doctor. Primolut N tablets should be swallowed whole with some water, preferably with food.
