⚠ Boxed Warning (Black Box)

WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS Cigarette smoking increases the risk of serious cardiovascular events from combined hormonal contraceptive (CHC) use. This risk increases with age, particularly in females over 35 years of age, and with the number of cigarettes smoked. For this reason, CHCs, including NEXTSTELLIS, are contraindicated in females who are over 35 years of age and smoke. [See Contraindications (4) and Warnings and Precautions (5.1) ] WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS See full prescribing information for complete boxed warning . Females over 35 years old who smoke should not use NEXTSTELLIS ( 4 ) Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptive (COC) use. ( 4 )

Dosage and Administration

2 DOSAGE AND ADMINISTRATION Take one tablet by mouth at the same time every day. ( 2.1 ) Take tablets in the order directed on the blister pack. ( 2.1 ) 2.1 Recommended Dosage and Administration Start NEXTSTELLIS using a Day 1 start. Take one tablet by mouth at the same time every day with or without food. 2.2 Additional Administration Information To achieve maximum contraceptive effectiveness, take one tablet every day at about the same time each day. The recommended dosage of NEXTSTELLIS is one tablet daily for 28 consecutive days: one pink active tablet daily during the first 24 days followed by one white inactive tablet daily during the 4 following days (see Table 1 ).

Drug Interactions

7 DRUG INTERACTIONS CYP3A Inducers: May lead to contraceptive failure and/or increase breakthrough bleeding. Avoid concomitant use. If concomitant use is unavoidable, use an alternative or back-up contraceptive method during co-administration and up to 28 days after discontinuation of the CYP3A inducer. ( 7.1 ) See Full Prescribing Information for additional clinically significant drug interactions ( 7 ). 7.1 Effects of Other Drugs on Hormonal Contraceptives Clinically significant drug interactions with other drugs that affect NEXTSTELLIS are presented in Table 5. Table 5. Clinically Significant Drug Interactions With Other Drugs that Affect NEXTSTELLIS CYP3A Inducers Clinical Effect DRSP is a CYP3A4 substrate. Concomitant use with strong CYP3A inducers or certain moderate or weak CYP3A inducers may decrease DRSP exposure [see Clinical Pharmacology (12.3) ] , which may lead to contraceptive failure. Prevention or Management Strong CYP3A Inducers Avoid concomitant use. If concomitant use is unavoidable, use an alternative contraceptive method (e.g., intrauterine system) or backup non-hormonal contraceptive method during coadministration and up to 28 days after discontinuation of the strong CYP3A inducer. Moderate and Weak CYP3A Inducers Use an alternative or backup contraceptive method during coadministration and up to 28 days after discontinuation of the CYP3A inducer, unless the Prescribing Information of the specific moderate or weak CYP3A inducer indicates there is no clinically significant interaction with NEXTSTELLIS. Strong CYP3A Inhibitors Clinical Effect DRSP is a CYP3A4 substrate. Concomitant use with a strong CYP3A inhibitor may increase DRSP exposure [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions of NEXTSTELLIS, including hyperkalemia [see Warnings and Precautions (5.2) ] . Prevention or Management Consider monitoring serum potassium concentration in patients who take a strong CYP3A4 inhibitor long-term and concomitantly with NEXTSTELLIS. Drugs that May Reduce the Absorption of NEXTSTELLIS Clinical Effect Concomitant use with drugs such as bile acid sequestrants may decrease the E4 and DRSP exposure, which may lead to contraceptive failure and/or an increase in breakthrough bleeding. Prevention or Management Separate time of administration of NEXTSTELLIS and the concomitant drug. Refer to the concomitant drug's Prescribing Information for additional information. 7.2 Effects of NEXTSTELLIS on Other Drugs Table 6 includes clinically significant drug interactions with NEXTSTELLIS that affect other drugs. Table 6. Clinically Significant Drug Interactions of NEXTSTELLIS on Other Drugs Anti-Diabetic Drugs Clinical Effect Concomitant use of NEXTSTELLIS may reduce the blood glucose lowering effect of anti-diabetic drugs [see Warnings and Precautions (5.8) and Clinical Pharmacology (12.2) . Prevention or Management Increase frequency of glucose monitoring and increase anti-diabetic drug dosage, as...

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary Discontinue NEXTSTELLIS if pregnancy occurs, because there is no reason to use hormonal contraceptives during pregnancy [see Contraindications (4) ] . Epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to COCs before conception or during early pregnancy. Reproductive toxicity studies performed with E4 alone have shown expected pharmacologic effects in animals, which are considered consistent with estrogen exposure. 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.

Overdosage

10 OVERDOSAGE Overdosage of CHCs may cause nausea, vomiting, and severe headaches. Individual reports of thromboembolic complications and vaginal bleeding have occurred from overdosage. Pediatric patients with unintended CHC ingestion have reported nausea and vomiting and some developed irritability and drowsiness; rare reports described vaginal bleeding. Overdosage Management Recommendations Consider short-term prophylactic anticoagulation therapy for patients with high risk of VTE. Monitor serum potassium and sodium levels, and for evidence of metabolic acidosis.
