Aygestin (norethindrone) is a form of progesterone, a female hormone, used for birth control (contraception) to prevent pregnancy. Aygestin is also used to treat menstrual disorders, endometriosis, or abnormal vaginal bleeding caused by a hormone imbalance. Aygestin is available in generic form.
The dosage and the duration of treatment with Aygestin is based on the patient's medical condition and response to therapy. Follow doctor's instructions. Withdrawal bleeding usually occurs within three to seven days after discontinuing Aygestin therapy.
