Warnings for Seasonale
Included as part of the "PRECAUTIONS" Section
Precautions for Seasonale
Thromboembolic Disorders And Other Vascular Conditions
- Stop SEASONALE if an arterial or venous thrombotic/thromboembolic event occurs.
- Stop SEASONALE if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions. Evaluate for retinal vein thrombosis immediately.
- Discontinue SEASONALE during prolonged immobilization. If feasible, stop SEASONALE at least 4 weeks before and through 2 weeks after major surgery or other surgeries known to have an elevated risk of thromboembolism.
- Start SEASONALE no earlier than 4 weeks after delivery in females who are not breastfeeding. The risk of postpartum thromboembolism decreases after the third postpartum week, whereas the likelihood of ovulation increases after the third postpartum week.
- Before starting SEASONALE evaluate any past medical history or family history of thrombotic or thromboembolic disorders and consider whether the history suggests an inherited or acquired hypercoagulopathy. SEASONALE is contraindicated in females with a high risk of arterial or venous thrombotic/thromboembolic diseases [see CONTRAINDICATIONS].
Arterial Events
COCs increase the risk of cardiovascular events and cerebrovascular events, such as myocardial infarction and stroke. The risk is greater among older women (> 35 years of age), smokers, and females with hypertension, dyslipidemia, diabetes, or obesity.
SEASONALE is contraindicated in women over 35 years of age who smoke [see CONTRAINDICATIONS]. Cigarette smoking increases the risk of serious cardiovascular events from COC use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked.
Venous Events
Use of COCs increases the risk of venous thromboembolic events (VTEs), such as deep vein thrombosis and pulmonary embolism. Risk factors for VTEs include smoking, obesity, and family history of VTE, in addition to other factors that contraindicate use of COCs [see CONTRAINDICATIONS]. While the increased risk of VTE associated with use of COCs is well-established, the rates of VTE are even greater during pregnancy, and especially during the postpartum period (see Figure 1). The rate of VTE in females using COCs has been estimated to be 3 to 9 cases per 10,000 woman years.
The risk of VTE is highest during the first year of use of a COC and when restarting hormonal contraception after a break of four weeks or longer. The risk of thromboembolic disease due to COCs gradually disappears after COC use is discontinued.
Figure 1 shows the risk of developing a VTE for females who are not pregnant and do not use oral contraceptives, for females who use oral contraceptives, for pregnant females and for females in the postpartum period. To put the risk of developing a VTE into perspective: If 10,000 females who are not pregnant and do not use oral contraceptives are followed for one year, between 1 and 5 of these females will develop a VTE.

| * Pregnancy data based on actual duration of pregnancy in the reference studies. Based on a model assumption that pregnancy duration is nine months, the rate is 7 to 27 per 10,000 WY. |
Use of SEASONALE provides women with more hormonal exposure on a yearly basis than conventional monthly COCs containing the same strength synthetic estrogens and progestins (an additional 9 weeks of exposure per year). In the clinical trial, one case of pulmonary embolism was reported. Postmarketing adverse reactions of VTE have been reported in women who used SEASONALE.
Liver Disease
Elevated Liver Enzymes
SEASONALE is contraindicated in females with acute viral hepatitis or severe (decompensated) cirrhosis of the liver [see CONTRAINDICATIONS]. Acute liver test abnormalities may necessitate the discontinuation of SEASONALE until the liver tests return to normal and SEASONALE causation has been excluded. Discontinue SEASONALE if jaundice develops.
Liver Tumors
SEASONALE is contraindicated in females with benign and malignant liver tumors [see CONTRAINDICATIONS]. COCs increase the risk of hepatic adenomas. An estimate of the attributable risk is 3.3 cases/100,000 COC users. Rupture of hepatic adenomas may cause death through intra-abdominal hemorrhage.
Studies have shown an increased risk of developing hepatocellular carcinoma in long-term (>8 years) COC users. The attributable risk of liver cancers in COC users is less than one case per million users.
Risk Of Liver Enzyme Elevations With Concomitant Hepatitis C Treatment
During clinical trials with the Hepatitis C combination drug regimen that contains ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, ALT elevations greater than 5 times the upper limit of normal (ULN), including some cases greater than 20 times the ULN, were significantly more frequent in women using ethinyl estradiol-containing medications, such as SEASONALE. Discontinue SEASONALE prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir [see CONTRAINDICATIONS]. SEASONALE can be restarted approximately 2 weeks following completion of treatment with the Hepatitis C combination drug regimen.
Hypertension
SEASONALE is contraindicated in females with uncontrolled hypertension or hypertension with vascular disease [see CONTRAINDICATIONS]. For all women, including those with well-controlled hypertension, monitor blood pressure at routine visits and stop SEASONALE if blood pressure rises significantly.
An increase in blood pressure has been reported in females taking COCs, and this increase is more likely in older women and with extended duration of use. The effect of COCs on blood pressure may vary according to the progestin in the COC.
Age-Related Considerations
The risk for cardiovascular disease and prevalence of risk factors for cardiovascular disease increase with age. Certain conditions, such as smoking and migraine headache without aura, that do not contraindicate COC use in younger females, are contraindications to use in women over 35 years of age [see CONTRAINDICATIONS and Thromboembolic Disorders And Other Vascular Conditions]. Consider the presence of underlying risk factors that may increase the risk of cardiovascular disease or VTE, particularly before initiating SEASONALE for women over 35 years, such as:
- Hypertension
- Diabetes
- Dyslipidemia
- Obesity
Gallbladder Disease
Studies suggest a small increased relative risk of developing gallbladder disease among COC users. Use of COCs, including SEASONALE, may worsen existing gallbladder disease.
A past history of COC-related cholestasis predicts an increased risk with subsequent COC use. Females with a history of pregnancy-related cholestasis may be at an increased risk for COC-related cholestasis.
Adverse Carbohydrate And Lipid Metabolic Effects
Hyperglycemia
SEASONALE is contraindicated in diabetic women over age 35, or females who have diabetes with hypertension, nephropathy, retinopathy, neuropathy, other vascular disease or females with diabetes of >20 years of duration [see CONTRAINDICATIONS]. SEASONALE may decrease glucose tolerance. Carefully monitor prediabetic and diabetic females who are using SEASONALE.
Dyslipidemia
Consider alternative contraception for females with uncontrolled dyslipidemia. SEASONALE may cause adverse lipid changes.
Females with hypertriglyceridemia, or a family history thereof, may have an increase in serum triglyceride concentrations when using SEASONALE, which may increase the risk of pancreatitis.
Headache
SEASONALE 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 headaches with or without aura [see CONTRAINDICATIONS].
If a female taking SEASONALE develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue SEASONALE if indicated. Consider discontinuation of SEASONALE if there is an increased frequency or severity of migraine during COC use (which may be prodromal of a cerebrovascular event) [see CONTRAINDICATIONS].
Bleeding Irregularities And Amenorrhea
Bleeding and/or spotting that occurs at any time while taking the first 84 tablets of each extended-cycle regimen is considered “unscheduled” bleeding/spotting. Bleeding that occurs during the time a woman takes the seven white inert tablets is considered “scheduled” bleeding.
Unscheduled Bleeding And Spotting
Females using SEASONALE may experience unscheduled (breakthrough or intracyclic) bleeding and spotting especially during the first 3 months of use. Bleeding irregularities may resolve over time or by changing to a different contraceptive product. If unscheduled bleeding persists or occurs after previously regular cycles, evaluate for causes such as pregnancy or malignancy.
Before prescribing SEASONALE, advise the woman to weigh the occurrence of fewer scheduled menses (4 per year instead of 13 per year) against the occurrence of increased unscheduled bleeding and/or spotting.
The clinical trial of the efficacy of SEASONALE (91-day cycles) in preventing pregnancy also assessed scheduled and unscheduled bleeding. The participants in the study were composed primarily of women who had used oral contraceptives previously as opposed to new users. Women with a history of breakthrough bleeding/spotting ≥ 10 consecutive days on oral contraceptives were excluded from the study. More SEASONALE subjects, compared to subjects on the comparator 28-day cycle regimen, discontinued prematurely for unacceptable bleeding (7.7% [SEASONALE] vs. 1.8% [28-day cycle regimen]).
Unscheduled bleeding and unscheduled spotting decreased over successive 91-day cycles. Table 3 below presents the number of days with unscheduled bleeding and/or spotting for each respective 91-day cycle.

Amenorrhea And Oligomenorrhea
Females who use SEASONALE may experience absence of scheduled (withdrawal) bleeding, even if they are not pregnant. Based on data from the clinical trial of SEASONALE, amenorrhea occurred in approximately 0.8% of females during Cycle 1, 1.2% of females during Cycle 2, 3.7% of females during Cycle 3, and 3.4% of females during Cycle 4.
Because females using SEASONALE will likely have scheduled bleeding only 4 times per year, rule out pregnancy at the time of any missed menstrual period.
After discontinuation of SEASONALE, amenorrhea or oligomenorrhea may occur, especially if these conditions were pre-existent.
Depression
Carefully observe females with a history of depression and discontinue SEASONALE if depression recurs to a serious degree. Data on the association of COCs with onset of depression or exacerbation of existing depression are limited.
Malignant Neoplasms
Breast Cancer
SEASONALE is contraindicated in females who currently have or have had breast cancer because breast cancer may be hormonally sensitive [see CONTRAINDICATIONS].
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 Postmarketing Experience].
Cervical Cancer
Some studies suggest that COC are associated with an increase in the risk of cervical cancer or intraepithelial neoplasia. However, there is controversy about the extent to which such findings may be due to differences in sexual behavior and other factors.
Effect On Binding Globulins
The estrogen component of SEASONALE may raise the serum concentrations of thyroxine-binding globulin, sex hormone-binding globulin and cortisol-binding globulin. The dose of replacement thyroid hormone or cortisol therapy may need to be increased.
Hereditary Angioedema
In females with hereditary angioedema, exogenous estrogens, including SEASONALE, may induce or exacerbate symptoms of hereditary angioedema.
Chloasma
Chloasma may occur with SEASONALE use, especially in females with a history of chloasma gravidarum. Advise females with a history of chloasma to avoid exposure to the sun or ultraviolet radiation while taking SEASONALE.
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (PATIENT INFORMATION and Instructions for Use).
Cigarette Smoking
Cigarette smoking increases the risk of serious cardiovascular events from COC use. Women who are over 35 years old and smoke should not use SEASONALE [see BOXED WARNING and WARNINGS AND PRECAUTIONS].
Venous Thromboembolism
The increased risk of VTE compared to non-users of COCs is greatest after initially starting a COC or restarting (following a 4-week or greater pill-free interval) the same or a different COC [see WARNINGS AND PRECAUTIONS].
Use During Pregnancy
Instruct females to stop further intake of SEASONALE if pregnancy is confirmed during treatment.
Sexually Transmitted Infections
SEASONALE does not protect against HIV-infection (AIDS) and other sexually transmitted infections.
Dosing And Missed Pill Instructions
- Patients should take one tablet daily by mouth at the same time every day [see DOSAGE AND ADMINISTRATION].
- Instruct patients what to do in the event tablets are missed. See “What should I do if I miss any SEASONALE pills” section in FDA-approved Instructions for Use [see DOSAGE AND ADMINISTRATION].
Need For Additional Contraception
- Postpartum females who start SEASONALE who have not yet had a period when they start SEASONALE need to use an additional method of contraception until they have taken a pink tablet for 7 consecutive days [see DOSAGE AND ADMINISTRATION].
- There is a need for a back-up or alternative method of contraception when enzyme inducers are used with SEASONALE [see DRUG INTERACTIONS].
Lactation
SEASONALE may reduce breast milk production. This is less likely to occur if breastfeeding is well established. When possible, nursing women should use other methods of contraception until they have discontinued breastfeeding [see Use In Specific Populations].
Amenorrhea And Possible Symptoms Of Pregnancy
Amenorrhea may occur. Because women using SEASONALE will likely have scheduled bleeding only 4 times per year, advise women to contact their health care provider in the event of amenorrhea with symptoms of pregnancy such as morning sickness or unusual breast tenderness [see WARNINGS AND PRECAUTIONS].
Depression
Depressed mood and depression may occur. Women should contact their healthcare provider if mood changes and depressive symptoms occur, including shortly after initiating the treatment [see WARNINGS AND PRECAUTIONS].

Use In Specific Populations
Pregnancy
Risk Summary
There is no use for contraception in pregnancy; therefore, SEASONALE should be discontinued during pregnancy. 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 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.
Lactation
Risk Summary
Contraceptive hormones and/or metabolites are present in human milk. COCs can reduce milk production in breastfeeding females. This reduction can occur at any time but is less likely to occur once breastfeeding is well-established. When possible, advise the nursing female to use other methods of contraception until she discontinues breastfeeding [see DOSAGE AND ADMINISTRATION]. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for SEASONALE and any potential adverse effects on the breastfed child from SEASONALE or the underlying maternal condition.
Pediatric Use
Safety and efficacy of SEASONALE have been established in women of reproductive age. Efficacy is expected to be the same for postpubertal adolescents under the age of 18 as for users 18 years and older. Use of SEASONALE before menarche is not indicated.
Geriatric Use
SEASONALE has not been studied in postmenopausal women and is not indicated in this population.
Hepatic Impairment
The pharmacokinetics of SEASONALE have not been studied in subjects with hepatic impairment. However, COCs may be poorly metabolized in patients with hepatic impairment. SEASONALE is contraindicated in females with acute hepatitis or severe decompensated cirrhosis [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS].
