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.

Changes in Contraceptive Effectiveness Associated with Co-Administration of Other Products If a woman on hormonal contraceptives takes a drug or herbal product that induces enzymes, including CYP3A4, that metabolize contraceptive hormones, counsel her to use additional contraception or a different method of contraception.
