Aygestin (Norethindrone Acetate) - Indications and Dosage

 
 



INDICATIONS AND USAGE

AYGESTIN® is indicated for the treatment of secondary amenorrhea, endometriosis, and abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology, such as submucous fibroids or uterine cancer. AYGESTIN ®  is not intended, recommended or approved to be used with concomitant estrogen therapy in postmenopausal women for endometrial protection.

DOSAGE AND ADMINISTRATION

Therapy with AYGESTIN® must be adapted to the specific indications and therapeutic response of the individual patient.

Secondary amenorrhea, abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology

2.5 to 10 mg AYGESTIN® may be given daily for 5 to 10 days to produce secretory transformation of an endometrium that has been adequately primed with either endogenous or exogenous estrogen.

Progestin withdrawal bleeding usually occurs within three to seven days after discontinuing AYGESTIN® therapy. Patients with a past history of recurrent episodes of abnormal uterine bleeding may benefit from planned menstrual cycling with AYGESTIN®.

Endometriosis

Initial daily dosage of 5 mg AYGESTIN® for two weeks. Dosage should be increased by 2.5 mg per day every two weeks until 15 mg per day of AYGESTIN® is reached. Therapy may be held at this level for six to nine months or until annoying breakthrough bleeding demands temporary termination.
