التداخل بين إستروجينات مؤسترة وميثيل تستوستيرون ونوريثيستيرون

CONTRAINDICATIONS Progestin-only oral contraceptives (POPs) should not be used by women who currently have the following conditions: • Known or suspected pregnancy • Known or suspected carcinoma of the breast.

Norethindrone tablets do not contain estrogen and, therefore, this insert does not discuss the serious health risks that have been associated with the estrogen component of combined oral contraceptives (COCs).

The healthcare professional is referred to the prescribing information of combined oral contraceptives for a discussion of those risks.

The relationship between progestin-only oral contraceptives and these risks is not fully defined.

Irregular Genital Bleeding Irregular menstrual patterns are common among women using progestin-only oral contraceptives.

(See WARNINGS, Malignant Neoplasms, Endometrial Cancer. ) CARDIOVASCULAR AND OTHER RISKS Estrogens with or without progestins should not be used for the prevention of cardiovascular disease.

(See CLINICAL PHARMACOLOGY, Clinical Studies. ) Other doses of oral conjugated estrogens with medroxyprogesterone acetate, and other combinations and dosage forms of estrogens and progestins were not studied in the WHI clinical trials and, in the absence of comparable data, these risks should be assumed to be similar.

Because of these risks, estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.

Do not use estrogens with or without progestins to prevent heart disease, heart attacks, or strokes.

Using estrogens with or without progestins may increase your chances of getting heart attacks, strokes, breast cancer, and blood clots.
