( 1 ) • The efficacy of Natazia in females of reproductive potential with a body mass index (BMI) of >30 kg/m 2 has not been evaluated. ( 1 , 8.8 ) • Treatment of heavy menstrual bleeding in females of reproductive potential without organic pathology who choose to use an oral contraceptive as their method of contraception. ( 1.2 ) 1.1 Oral Contraception Natazia ® is indicated for use by women to prevent pregnancy. The efficacy of Natazia in women with a body mass index (BMI) of > 30 kg/m 2 has not been evaluated. 1.2 Heavy Menstrual Bleeding Natazia is also indicated for the treatment of heavy menstrual bleeding in women without organic pathology who choose to use an oral contraceptive as their method of contraception [see Clinical Studies ( 14.2 )].

Natazia is contraindicated in females who are known to have or develop the following conditions: • A high risk of arterial or venous thrombotic diseases. Examples include women who are known to: • Smoke, if over age 35 [see Boxed Warning and Warnings and Precautions ( 5.1 )] • Have deep vein thrombosis or pulmonary embolism, now or in the past [see Warnings and Precautions ( 5.1 )] • Have cerebrovascular disease [see Warnings and Precautions ( 5.1 )] • Have coronary artery disease [see Warnings and Precautions ( 5.1 )] • Have thrombogenic valvular or thrombogenic rhythm diseases of the heart (for example, subacute bacterial endocarditis with valvular disease, or atrial fibrillation) [see Warnings and Precautions ( 5.1 )] • Have inherited or acquired hypercoagulopathies [see Warnings and Precautions ( 5.1 )] • Have uncontrolled hypertension [see Warnings and Precautions ( 5.4 )] • Have diabetes mellitus with vascular disease [see Warnings and Precautions ( 5.6 )] • Have headaches with …

• Vascular risks : Stop Natazia if a thrombotic event occurs. Stop Natazia at least 4 weeks before and through 2 weeks after major surgery. Start Natazia no earlier than 4 weeks after delivery, in women who are not breastfeeding. ( 5.1 ) • Liver disease : Discontinue Natazia if jaundice occurs. ( 5.3 ) • High blood pressure : Do not prescribe Natazia for women with uncontrolled hypertension or hypertension with vascular disease.

( 5.8 ) • CYP3A4 induction : Women taking strong CYP3A4 inducers (for example, carbamazepine, phenytoin, rifampicin, and St. John’s wort) should not choose Natazia as their oral contraceptive due to the possibility of decreased contraceptive efficacy. ( 5.13 , 7.1 ) 5.1 Thromboembolic Disorders and Other Vascular Problems Stop Natazia if an arterial or venous thrombotic event (VTE) occurs. The use of COCs increases the risk of venous thromboembolism. However, pregnancy increases the risk of venous thromboembolism as much or more than the use of COCs. The risk of VTE in women using COCs has been estimated to be 3 to 9 per 10,000 woman-years. The risk of VTE is highest during the first year of …

8.1 Pregnancy Risk Summary There is no reason to use COCs in pregnancy Discontinue Natazia if pregnancy occurs. Epidemiologic studies and meta-analyses have not found an increased risk of genital or non-genital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to COCs prior to conception or during early pregnancy. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4 percent and 15 to 20 percent, respectively.
