PRECAUTIONS
Thromboembolic Disorders And Other Vascular Conditions
Females are at increased risk for a venous thrombotic event (VTE) when using ANNOVERA™. Limited data are available in females with a BMI >29.0 kg/m2 because this subpopulation was excluded from the clinical trials after VTEs were reported.
- Stop ANNOVERA™ if an arterial or deep venous thrombotic event occurs.
- Stop ANNOVERA™ if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions and evaluate for retinal vein thrombosis immediately.
- Discontinue ANNOVERA™ during prolonged immobilization. If feasible, stop ANNOVERA™ at least 4 weeks before and through 2 weeks after major surgery or other surgeries known to have an elevated risk of VTE.
- Start ANNOVERA™ no earlier than 4 weeks after delivery in females who are not breastfeeding. The risk of postpartum VTE decreases after the third postpartum week, whereas the risk of ovulation increases after the third postpartum week.
- Before starting ANNOVERA™, evaluate any past medical history or family history of thrombotic or thromboembolic disorders and consider whether the history suggests an inherited or acquired hypercoagulopathy. ANNOVERA™ is contraindicated in females with a high risk of arterial or venous thrombotic/thromboembolic diseases
[see CONTRAINDICATIONS].
Arterial Events
CHCs increase the risk of cardiovascular events and cerebrovascular events, such as stroke and myocardial infarction. The risk is greater among older females (>35 years of age), smokers, and females with hypertension, dyslipidemia, diabetes, or obesity.
ANNOVERA™ is contraindicated in females over 35 years of age who smoke [see CONTRAINDICATIONS]. Cigarette smoking increases the risk of serious cardiovascular events from CHC use. This risk increases with age, particularly in females over 35 years of age, and with the number of cigarettes smoked.
Venous Events
The use of CHCs increases the risk of VTE, 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 CHCs [see CONTRAINDICATIONS]. While the increased risk of VTE associated with use of CHCs 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 CHCs has been estimated to be 3–12 cases per 10,000 woman-years.
The risk of VTE is highest during the first year of CHC use and when restarting hormonal contraception following a break of 4 weeks or longer. The risk of VTE due to CHCs gradually disappears after use is discontinued.
Figure 1 shows the risk of developing a VTE for females who are not pregnant and do not use CHCs, for females who use CHCs, 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 CHCs are followed for 1 year, between 1 and 5 of these women will develop a VTE.
Figure 1
* CHC = combination hormonal contraception
** Pregnancy data based on actual duration of pregnancy in the reference studies. Based on a model assumption that pregnancy duration is 9 months, the rate is 7 to 27 per 10,000 WY.
Liver Disease
Impaired Liver Function
ANNOVERA™ is contraindicated in females with acute hepatitis or severe (decompensated) cirrhosis of the liver [see CONTRAINDICATIONS]. Discontinue ANNOVERA™ if jaundice develops. Acute liver test abnormalities may necessitate the discontinuation of ANNOVERA™ use until the liver tests return to normal and ANNOVERA™ causation has been excluded.
Liver Tumors
ANNOVERA™ is contraindicated in females with benign or malignant liver tumors [see CONTRAINDICATIONS]. Hepatic adenomas are associated with CHC use. An estimate of the attributable risk is 3.3 cases/100,000 CHC 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) CHC users. The attributable risk of liver cancers in CHC 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 and 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 females using ethinyl estradiol-containing medications, such as ANNOVERA™. Discontinue ANNOVERA™ prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir [see CONTRAINDICATIONS]. ANNOVERA™ can be restarted approximately 2 weeks following completion of treatment with the Hepatitis C combination drug regimen.
Hypertension
ANNOVERA™ is contraindicated in females 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 ANNOVERA™ 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 females and with extended duration of use. The effect of CHCs on blood pressure may vary according to the progestin in the CHC.
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 CHC 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 ANNOVERA™ 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 CHC users. Use of CHCs may also worsen existing gallbladder disease.
A past history of CHC-related cholestasis predicts an increased risk with subsequent CHC use. Females with a history of pregnancy-related cholestasis may be at an increased risk for CHC-related cholestasis.
Adverse Carbohydrate And Lipid Metabolic Effects
Hyperglycemia
ANNOVERA™ is contraindicated in diabetic females over age 35, or females who have diabetes with hypertension, nephropathy, retinopathy, neuropathy, other vascular disease, or females with diabetes of >20 years duration [see CONTRAINDICATIONS]. ANNOVERA™ may decrease glucose tolerance. Carefully monitor prediabetic and diabetic females who are taking ANNOVERA™.
Dyslipidemia
Consider alternative contraception for females with uncontrolled dyslipidemia. ANNOVERA™ may cause adverse lipid changes.
Females with hypertriglyceridemia, or a family history thereof, may be at an increased risk of pancreatitis when using ANNOVERA™.
Headache
ANNOVERA™ is contraindicated in females who have headaches with focal neurological symptoms or have migraine headaches with aura, and in females over age 35 years who have migraine headaches with or without aura [see CONTRAINDICATIONS].
If a woman taking ANNOVERA™ develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue ANNOVERA™ if indicated.
Consider discontinuation of ANNOVERA™ in the case of increased frequency or severity of migraine during CHC 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 the vaginal system is inserted is considered “unscheduled” bleeding/spotting. Bleeding/spotting that occurs during the dose-free week when the vaginal system is out is considered “scheduled” bleeding.
Unscheduled And Scheduled Bleeding And Spotting
Females using ANNOVERA™ may experience unscheduled (breakthrough) bleeding and spotting, especially during the first month of use. If unscheduled bleeding persists or occurs after previously regular cycles on ANNOVERA™, check for causes such as pregnancy or malignancy. If pathology and pregnancy are excluded, bleeding irregularities may resolve over time or with a change to a different CHC.
Based on subject diaries from the two clinical efficacy trials of ANNOVERA™ [see Clinical Trial Experience], 5–10% of females experienced unscheduled bleeding per 28-day cycle. The average number of days with unscheduled bleeding and/or spotting, in Treatment Cycles 1 to 13 for those females who experienced unscheduled bleeding and/or spotting, was 1 day or less per cycle. A total of 41 subjects (1.7%) discontinued use due to menstrual disorders including metrorrhagia, menorrhagia, and abnormal withdrawal bleeding.
Amenorrhea And Oligomenorrhea
Females who are not pregnant and use ANNOVERA™ may experience amenorrhea. Based on subject diary data from two clinical trials for up to 13 cycles, amenorrhea occurred in 3–5% of females per cycle using ANNOVERA™ and in 0.9% of females in all 13 cycles.
If scheduled bleeding does not occur, consider the possibility of pregnancy. If the patient has not adhered to the prescribed dosing schedule (removed vaginal system for >2 hours during the first 21 days, or does not replace after 7 days of vaginal system-free period), consider the possibility of pregnancy at the time of the first missed period and perform a pregnancy test. If the patient has adhered to the prescribed dosing schedule and misses 2 consecutive periods, perform a pregnancy test to rule out pregnancy.
Some females may experience amenorrhea or oligomenorrhea after stopping ANNOVERA™, especially when such a condition was pre-existent.
Depression
Carefully observe females with a history of depression and discontinue ANNOVERA™ if depression recurs to a serious degree. Data on the association of CHCs with onset of depression or exacerbation of existing depression are limited.
Cervical Cancer
Some studies suggest that CHCs are associated with an increase in the risk of cervical cancer or intraepithelial neoplasia. However, there is controversy about the extent to which these findings are due to differences in sexual behavior and other factors.
Effect On Binding Globulins
The estrogen component of ANNOVERA™ 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 AngioedemaM
In females with hereditary angioedema, exogenous estrogens may induce or exacerbate symptoms of angioedema.
Chloasma
Chloasma may occur with ANNOVERA™ use, especially in females with a history of chloasma gravidarum. Advise females who tend to develop chloasma to avoid exposure to the sun or ultraviolet radiation while using ANNOVERA™.
Toxic Shock Syndrome (TSS)
Cases of TSS have been reported by vaginal ring users. TSS has been associated with tampons and certain barrier contraceptives, and in some TSS cases ring users were also using tampons. Causal relationship between the use of a vaginal ring and TSS has not been established. No cases of TSS occurred in clinical trials with ANNOVERA™. If a patient exhibits signs or symptoms of TSS, consider the possibility of this diagnosis, remove ANNOVERA™, and initiate appropriate medical evaluation and treatment.
Vaginal Use
Some females are aware of the vaginal system on occasion during the 21 days of use or during coitus, and partners may feel the vaginal system during coitus.
There is no information on the concomitant use of ANNOVERA™ with diaphragms, cervical caps, and female condoms.
ANNOVERA™ may not be suitable for females with conditions that make the vagina more susceptible to vaginal irritation or ulceration. Vaginal and cervical erosion and/or ulceration has been reported in females using other contraceptive vaginal devices. In some cases, the ring adhered to vaginal tissue, which necessitated removal by a health-care provider.
Patient Counseling Information
Advise the patient to read the FDA-approved Patient Information (see PATIENT INFORMATION and
Instructions for Use).
Cigarette Smoking
Cigarette smoking increases the risk of serious cardiovascular events from CHC use, and females who are over 35 years old and smoke should not use ANNOVERA™ [see BOX WARNING and WARNINGS AND PRECAUTIONS].
Venous Thromboembolism
Increased risk of VTE compared to nonusers of CHCs is greatest after initially starting a CHC or restarting (following a 4-week or greater dose-free interval) the same or a different CHC [see WARNINGS AND PRECAUTIONS].
Sexually Transmitted Infections
ANNOVERA™ does not protect against HIV-infection (AIDS) and other sexually transmitted infections. ANNOVERA™ is compatible with male condoms made with natural rubber latex, polyisoprene, and polyurethane.
Use During Pregnancy
ANNOVERA™ is not to be used during pregnancy; instruct the patient to remove
ANNOVERA™ if pregnancy is confirmed during treatment [see Use In Specific Populations].
ANNOVERA™ Dosing And Instructions
Advise the woman on proper use of ANNOVERA™ and what to do if she does not comply with the labeled timing of insertion and removal. The efficacy of ANNOVERA™ is greatest when ANNOVERA™ is kept in the vagina continuously for the scheduled 21 consecutive days. Removal of ANNOVERA™ even briefly during the scheduled 21 days of use can reduce efficacy.
ANNOVERA™ should be washed with mild soap and water and rinsed and patted dry with a clean cloth towel or paper towel prior to each insertion and at each removal. Prior to initial use, the storage case should be labeled with the discard date to avoid using the product beyond 13 cycles [see DOSAGE AND ADMINISTRATION and FDA-approved PATIENT INFORMATION].
Place the completely used ANNOVERA™ in the case provided and discard via a drug take-back option if one is available. If a take-back option is unavailable, then discard in the waste receptacle out of reach of children and pets. The vaginal system should NOT be flushed down the toilet. See www.fda.gov/drugdisposal for more information about disposal of medicines. [see HOW SUPPLIED].
Use With Vaginal Products
Water-based vaginal lubricants have no effect on the vaginal system; however, oil-based (including silicone-based) vaginal lubricants will alter the vaginal system and/or exposure to EE and segesterone acetate and should not be used [see DRUG INTERACTIONS].
Need For Additional Contraception
Use a back-up or alternative method of contraception when:
Enzyme inducers are used with CHCs [see DRUG INTERACTIONS].
ANNOVERA™ has been out for more than 2 hours cumulative during the 21 days of continuous use or the vaginal system-free interval exceeds 7 days [see DOSAGE AND ADMINISTRATION].
Postpartum females who have not yet had a period should use an additional method of contraception until ANNOVERA™ has been in place for 7 consecutive days [see DOSAGE AND ADMINISTRATION].
Lactation
ANNOVERA™ may reduce breast milk production. This is less likely to occur if breastfeeding is well established. Females who are breastfeeding should not use ANNOVERA™ until after weaning [see Use In Specific Populations].
Amenorrhea And Possible Symptoms Of Pregnancy
Amenorrhea may occur. Consider pregnancy in the event of amenorrhea, and rule out pregnancy if amenorrhea is associated with symptoms of pregnancy, such as morning sickness or unusual breast tenderness [see WARNINGS AND PRECAUTIONS].
Fertility Following Discontinuation Of ANNOVERA™
Resumption of fertility after discontinuation of ANNOVERA™ is expected. All women followed for return of fertility experienced a return of fertility by 6 months after discontinuing ANNOVERA™ [see Clinical Studies].
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Carcinogenesis
In a 2-year carcinogenicity study in rats with subdermal implants releasing 40, 100, and 200 μg segesterone acetate per day (approximately 17–86 times the daily dose of segesterone acetate in females using ANNOVERA™, based on body surface area), no drug-related increase in tumor incidence was observed. In a 2-year intravaginal carcinogenicity study in mice, segesterone acetate gel produced an increased incidence of adenocarcinoma and lobular hyperplasia in the breast at a dose of 30 mg/kg/day, approximately 10 times the systemic exposure of segesterone acetate per day in females using ANNOVERA™, based on AUC. A dose of 10 mg/kg/day in the mouse, approximately 3 times the systemic exposure of segesterone acetate per day based on AUC, did not result in carcinogenic findings.
Long-term continuous administration of natural and synthetic estrogens in certain animal species increases the frequency of carcinomas of the breast, uterus, cervix, vagina, testis, and liver.
Mutagenesis
Segesterone acetate was neither mutagenic nor clastogenic in the Ames/Salmonella reverse mutation assay, the chromosomal aberration assay in Chinese hamster ovary cells, or in the in vivo mouse micronucleus test.
Impairment Of Fertility
A return to fertility study was conducted with segesterone acetate in rats, using subdermal implants releasing a dose approximately 25 times the anticipated daily vaginal human dose (based on body surface area). Three months of treatment with segesterone acetate suppressed fertility, but 7 weeks after cessation of treatment, there were no adverse effects on ovulation or resulting litter parameters.
Use In Specific Populations
Pregnancy
Risk Summary
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 CHCs 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 2–4% and 15–20%, respectively.
Discontinue ANNOVERA™ if pregnancy occurs, because there is no reason to use CHCs during pregnancy.
Data
Human Data
No studies have been conducted of the use of ANNOVERA™ in pregnant females.
Lactation
Risk Summary
Contraceptive hormones and/or metabolites are present in human milk. CHCs 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. Advise the nursing female to use another method of contraception until she discontinues breastfeeding. [see DOSAGE AND ADMINISTRATION.]
Data
Human Data
No studies have been conducted of the use of ANNOVERA™ in breastfeeding females. Two studies have been conducted in breastfeeding females of segesterone acetate implants delivering lower levels of segesterone acetate than ANNOVERA™. Maternal serum levels of up to 141 pg/ml were associated with infant exposure of up to 7 pg/ml. No safety signals in feeding, growth, and development were observed in the infants between the segesterone acetate implant group and the control group.
Pediatric Use
Safety and efficacy of ANNOVERA™ 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 ANNOVERA™ before menarche is not indicated.
Geriatric Use
ANNOVERA™ has not been studied in females who have reached menopause and is not indicated in this population.
Hepatic Impairment
No studies have been conducted to evaluate the effect of hepatic impairment on the disposition of ANNOVERA™. However, steroid hormones may be poorly metabolized in patients with hepatic impairment. Acute or chronic disturbances of liver function may necessitate the discontinuation of CHC use until markers of liver function return to normal and CHC causation has been excluded. [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS.]
Renal Impairment
No studies were conducted in subjects with renal impairment; ANNOVERA™ is not recommended in patients with renal impairment.
Body Mass Index (BMI)/Body Weight
The safety and efficacy of ANNOVERA™ in females with a BMI >29 kg/m2 have not been adequately evaluated because this subpopulation was excluded from the clinical trials after two VTEs occurred in females with a BMI > 29 kg/m2 [see ADVERSE REACTIONS and Clinical Studies]. Higher body weight is associated with lower systemic exposure of SA and EE [see CLINICAL PHARMACOLOGY].
