Aygestin (norethindrone) is a synthetic progestin hormone used to treat a variety of gynecological conditions, including endometriosis, abnormal uterine bleeding, and amenorrhea. It is also used as a form of contraception, either alone or in combination with an estrogen.
Aygestin works by preventing the ovaries from releasing an egg (ovulation) and by changing the lining of the uterus (endometrium) to prevent pregnancy. It also helps to regulate menstrual cycles, reduce menstrual cramps, and treat other menstrual-related problems.
Common side effects of Aygestin include nausea, vomiting, and headaches. Other side effects include breast tenderness, bloating, and weight gain. Rare but serious side effects include jaundice, depression, and blood clots. Women who are pregnant or breastfeeding should not take Aygestin.
The active ingredient in Aygestin is norethindrone, a synthetic form of the hormone progesterone. Other names for norethindrone include Norlutin, Norethin, Primolut-N, and Nor-QD.
Aygestin can be an effective treatment for a variety of gynecological conditions. However, it is important to talk to a healthcare provider about the potential risks and side effects before starting any medication.
