Possible Uses of Noriday: Norethisterone is used to mimic the effects of female sex hormones produced naturally by the body. It is a synthetic progestogen hormone, sometimes known as a progestogen-only oral contraceptive or the mini pill. It is used to thicken the vaginal fluid so that sperm cannot get to the womb and to change the lining of the womb so that eggs cannot grow there, preventing pregnancy. Norethisterone also decreases the production of oestrogen and progestogen hormones produced naturally by the body and may also have a direct effect on the pituitary gland which is involved in the production of several hormones.
In general this drug is used to treat irregular, painful or heavy periods, endometriosis (a painful condition caused by tissue that usually lines the womb growing outside the womb), premenstrual tension (also known as PMS or PMT) and to prevent pregnancy (oral contraceptive pill). Benefits of being on this drug can include prevention of pregnancy, return to a normal menstrual cycle, relief from the pain associated with endometriosis and relief from the symptoms of PMS or PMT.
Before using Noriday: Before taking norethisterone tell your doctor or pharmacist if you are allergic to it; or to other progestogens; or if you have any other allergies.
How to take Noriday: Take this medication by mouth usually once a day, with or without food. Swallow the tablet whole with a glass of water. If you are taking norethisterone as an oral contraceptive and you have a stomach upset (sickness and/or diarrhoea) within 2 hours of taking the tablet, then another pill should be taken as soon as possible. If a replacement pill is not taken within 3 hours of the usual pill taking time or in case of persistent sickness or severe diarrhoea, then carry on taking your tablet as usual but also use extra contraception for as long as you are ill and for the next 2 days after that.
Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day - unless specifically told not to by your doctor. Certain medical conditions may require different dosage instructions as directed by your doctor.
