NEXESTA FE (ethinyl estradiol)

AbsorptionEthinyl estradiol and norethindrone are rapidly absorbed with maximum plasma concentrations occurring within 2 hours after Nexesta Fe administration (see Table 1). Norethindrone appears to be completely absorbed following oral administration; however, it is subject to first-pass metabolism resulting in an absolute bioavailability of approximately 65 percent. Large intersubject variability is reflected in a 3- to 5-fold variation in norethindrone bioavailability. Ethinyl estradiol bioa...

The data presented in Section 14 are from a clinical trial conducted with norethindrone 0.4 mg/ethinyl estradiol 0.035 mg tablets. Nexesta Fe is bioequivalent to these norethindrone acetate/ethinyl estradiol tablets. In a multicenter open-label clinical trial, 1,970 women, 98% of whom were 16 to 39 years of age, were studied for up to 31 cycles (28 days per cycle) to assess the efficacy of norethindrone/ethinyl estradiol tablets, completing the equivalent of 20,230 cycles of exposure. The racial demographic of all enrolled women was: Caucasian (56%), African-American (14%), and Other (30%) (Hi...

The following serious adverse reactions with the use of COCs are discussed elsewhere in the labeling: Serious cardiovascular events and stroke [see Boxed Warning and Warnings and Precautions (5.1) ] Vascular events [see Warnings and Precautions (5.1) ] Liver disease [see Warnings and Precautions (5.2) ] The following adverse reactions are commonly reported by COC users. Because these reactions are voluntarily reported by from a population of uncertain size, it is not always possible to reliably ...

Nexesta Fe 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: o Smoke, if over age 35 [see Boxed Warning and Warnings and Precautions (5.1) ] o Have deep vein thrombosis or pulmonary embolism, now or in the past [see Warnings and Precautions (5.1) ] o Have inherit...

Thrombotic Disorders and Other Vascular Problems: Stop Nexesta Fe if a thrombotic event occurs. Stop at least 4 weeks before through 2 weeks after major surgery. Start no earlier than 4 weeks after delivery, in women who are not breastfeeding ( 5.1 ) Liver disease : Discontinue Nexesta Fe if jaundice occurs ( 5.2 ) High blood pressure: If used in women with well-controlled hypertension, monitor blood pressure and stop Nexesta Fe if blood pressure rises significantly. ( 5.4 ) Carbohydrate and lip...

7 DRUG INTERACTIONS Consult the labeling of concurrently used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations. Drugs or herbal products that induce certain enzymes, including CYP3A4, may decrease the effectiveness of COCs or increase breakthrough bleeding. Counsel patients to use a back-up method or alternative method of c...
