Boxed Warning

WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS

Cigarette smoking increases the risk of serious cardiovascular events from combined oral contraceptives (COC) use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, COCs, including ALESSE, are contraindicated in women who are over 35 years of age and smoke.

4 Contraindications

Additions and/or revisions underlined:

Combination oral contraceptives should not be used in women with any of the following conditions:

Headaches with focal neurological symptoms or migraine with aura Women with migraine

Known or suspected carcinoma of the breast or personal history of breast cancer Known or suspected estrogen- or progesterone sensitive malignancy.

5 Warnings and Precautions

PRECAUTIONS

Additions and/or revisions underlined:

6.Depression

Monitor females with a history of depression and discontinue ALESSE if depression recurs to a serious degree. Data on the association of CHCs with onset of depression or exacerbation of existing depression are limited.

8.Gastrointestinal

Diarrhea and/or vomiting may reduce hormone absorption resulting in decreased serum concentrations. If a patient vomits or has diarrhea after taking an active tablet, instruct the patient to not take an additional active tablet on that day and to continue the regimen the next day as prescribed. In case of vomiting or diarrhea that continues for 48 hours or greater, instruct the patient to contact the health care provider and use back-up or alternative contraception until active tablets have been taken for 7 consecutive days after vomiting and diarrhea have resolved.

9.Drug Interactions

Changes in Plasma Levels of Co-Administered Drugs:

Concomitant use of ALESSE may decrease lamotrigine exposure, which may reduce efficacy of lamotrigine. Adjust lamotrigine dosage as recommended in its Prescribing Information based on ALESSE initiation or discontinuation.

Concomitant use of ALESSE may increase thyroid-binding globulin concentration. Monitor thyroid-stimulating hormone (TSH) level and follow the recommendation for the thyroid hormone in accordance with its Prescribing Information.

The prescribing information of concomitant medications should be consulted to identify potential interactions.

12.Pregnancy

Risk Summary

There is no use for contraception in pregnancy; therefore, ALESSE should be discontinued during pregnancy. 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.

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.

Data

Human Data

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.

13.Lactation

Contraceptive hormones and metabolites are present in human milk. CHCs can reduce milk production in breast-feeding females. This reduction can occur at any time but is less likely to occur once breast-feeding is well-established. The developmental and health benefits of breast-feeding should be considered along with the mother’s clinical need for ALESSE and any potential adverse effects on the breast-fed child from ALESSE or from the underlying maternal condition.

16.Body Mass Index

The safety and effectiveness of ALESSE in females with a BMI > 35 kg/m2 have not been adequately evaluated.

WARNINGS

Additions and/or revisions underlined:

1. Thromboembolic Disorders and Other Vascular Problems

Cardiovascular and Cerebrovascular Events

Use of CHCs increases the risk of cardiovascular events and cerebrovascular events, such as myocardial infarction and stroke. The risk of these events with CHC use is greater in females with concomitant risk factors: age 35 years and older, smoking, hypertension, dyslipidemia, diabetes, or obesity. The risk increases with increasing age and with increasing number of cigarettes smoked.

Venous Thromboembolism

Use of CHCs also increases the risk of VTE, such as deep vein thrombosis and pulmonary embolism.

The rate of VTE in females using COCs has been estimated to be 3 to 9 cases per 10,000 woman-years.

The VTE risk should be considered in the context of relevant subpopulations of females of reproductive potential who are not taking CHCs (ADVERSE REACTIONS).

Risk factors for VTE with CHC use include smoking, obesity, family history of VTE, and prolonged immobilization, in addition to other factors that contraindicate use of CHCs (see CONTRAINDICATIONS). The presence of multiple risk factors for VTE with CHC use may further increase the risk. The risk of VTE is highest during the first year of CHC use and when restarting hormonal contraception after a break of four weeks or longer. The risk of VTE returns to baseline approximately 3 months after CHC use is discontinued.

Postpartum Venous Thromboembolism

The risk of VTE is increased during the first six weeks postpartum. The risk is highest up to four weeks postpartum but remains higher than baseline until at least six weeks postpartum. The presence of multiple risk factors for VTE may further increase the risk. Obstetric complications may extend the elevated risk up to 12 weeks postpartum.

7.Gallbladder Disease

A past history of COC-related cholestasis predicts an increased risk with subsequent COC use. Women with a history of pregnancy-related cholestasis may be at an increased risk for COC related cholestasis.

8.Carbohydrate and Lipid Metabolic Effects

Carefully monitor females with prediabetes and diabetes who are using ALESSE. ALESSE may decrease glucose tolerance.

9.Elevated Blood Pressure

ALESSE is contraindicated in women with uncontrolled hypertension or hypertension with vascular disease (see CONTRAINDICATIONS). For all females, including those with well- controlled hypertension, monitor blood pressure at routine visits and stop ALESSE if blood pressure rises significantly.

An increase in blood pressure has been reported in females using CHCs, and this increase is more likely in older women with extended duration of use. The effect of CHCs on blood pressure may vary according to the progestin in the CHC.

10.Headache

ALESSE is contraindicated in females who have headaches with focal neurological symptoms or have migraine headaches with aura, and in women over age 35 years who have migraine head aches with or without aura.

The onset or exacerbation of migraine or development of headache with a new pattern that is recurrent, persistent, or severe requires discontinuation of oral contraceptives and evaluation of the cause. Consider discontinuation of ALESSE if there is an increased frequency or severity of migraines during CHC use (which may be prodromal of a cerebrovascular event; see WARNINGS and CONTRAINDICATIONS.)

11. Bleeding Irregularities

In the clinical trial with levonorgestrel 0.1 mg and ethinyl estradiol 0.02 mg tablets, unscheduled bleeding was defined as bleeding or spotting that occurred:

•           During cycle 1 on pill-pack Days 4 to 21, inclusive of a 28-day cycle.

•           In subsequent cycles, on Days 5 to 21 inclusive or on pill-pack Days 1 to 4 inclusive if preceded by 2 consecutive days without bleeding or spotting.

Based on subject diaries, the proportion of subjects reporting unscheduled bleeding or spotting per 28-day cycle decreased over time: 30.5% at Cycle 1 versus 18.2% at Cycle 12.

12.Hereditary Angioedema

In women with hereditary angioedema, exogenous estrogens may induce or exacerbate symptoms of angioedema.

13.Chloasma

Chloasma may occur, especially in women with a history of chloasma gravidarum. Advise women with a history of chloasma to avoid exposure to the sun or ultraviolet radiation while taking ALESSE.

14.Effect on Binding Globulins

The estrogen component of COCs may raise the serum concentrations of thyroxine-binding globulin, sex hormone-binding globulin, and cortisol-binding globulin. Monitor thyroid- stimulating hormone (TSH) levels for females receiving ALESSE and thyroid hormone replacement therapy concomitantly. Follow the recommendation for the thyroid hormone in accordance with its Prescribing Information.

6 Adverse Reactions

Additions and/or revisions underlined:

The following adverse reactions associated with the use of oral CHCs were identified in clinical studies or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Common adverse reactions associated with oral CHCs are headache, abdominal pain, nausea, metrorrhagia, vaginal moniliasis and pain, acne, and vaginitis.

Additional adverse reactions that have been reported include the following:

Eye disorder: intolerance to contact lenses, steepening of corneal curvature

Gastrointestinal disorders: Abdominal bloating, vomiting

General disorders and administration site conditions: Edema, fluid retention

Hepatobiliary disorders: Cholestatic jaundice

Pyschiatric disorders: Change in libido, mood changes

Reproductive system and breast disorders: Amenorrhea, breast tenderness, breast pain, breast enlargement, increased cervical mucous, change in menstrual flow, unscheduled bleeding

Skin and subcutaneous tissue disorders: Acne, melasma

Vascular disorders: Budd-Chiari syndrome, aggravation of varicose veins

4 Contraindications

Additions underlined

Combination oral contraceptives should not be used in women with any of the following

conditions:

Current diagnosis of, or history of, breast cancer, which may be hormone-sensitive

5 Warnings and Precautions

WARNINGS

Additions underlined

3.Malignant Neoplasms

Breast Cancer

ALESSE is contraindicated in females who currently have or have had breast cancer because breast cancer may be hormonally sensitive [see Contraindications (4)]. Epidemiology studies

have not found a consistent association between use of combined oral contraceptives (COCs) and breast cancer risk. Studies do not show an association between ever (current or past) use of COCs and risk of breast cancer. However, some studies report a small increase in the risk of breast cancer among current or recent users (<6 months since last use) and current users with longer duration of COC use [see ADVERSE REACTIONS].  

6 Adverse Reactions

Additions underlined

Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 - 1.12 (Figure 3).

Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 3). One of these studies reported no association between breast cancer risk and COC use. The other two studies found an increased relative risk of 1.19 - 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8-10 years of COC use.

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

PATIENT INFORMATION

Additions underlined

There may be slight increases in the risk of breast cancer among current users of hormonal birth control pills with longer duration of use of 8 years or more.

Some studies have found an increase in the incidence of cancer of the cervix in women who use oral contraceptives. However, this finding may be related to factors other than the use of oral contraceptives.

 

DETAILED PATIENT LABELING

Additions underlined

RISKS OF TAKING ORAL CONTRACEPTIVES

5.Risk of Cancer

It is not known if hormonal birth control pills causes breast cancer. Some studies, but not all,

suggest that there could be a slight increase in the risk of breast cancer among current users with

longer duration of use.

If you have breast cancer now, or have had it in the past, do not use hormonal birth control

because some breast cancers are sensitive to hormones.
