Boxed Warning

Cigarette smoke and serious cardiovascular events:

Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptives use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, combination oral contraceptives should not be used by women who are over 35 years of age and smoke.

Pharmacology

Mechanism of Action

Combination oral contraceptives inhibit ovulation via a negative feedback mechanism on the hypothalamus, which alters the normal pattern of gonadotropin secretion of a follicle-stimulating hormone (FSH) and luteinizing hormone by the anterior pituitary. The follicular phase FSH and midcycle surge of gonadotropins are inhibited. In addition, oral contraceptives produce alterations in the genital tract, including changes in the cervical mucus, rendering it unfavorable for sperm penetration even if ovulation occurs. Changes in the endometrium may also occur, producing an unfavorable environment for nidation. Oral contraceptive drugs may alter the tubal transport of the ova through the fallopian tubes. Progestational agents may also alter sperm fertility. Drospirenone is a spironolactone analogue with antimineralocorticoid and antiandrogenic activity.

Dosage and Administration

Dosing: Adult

Acne (Gianvi, Loryna, Nikki, Vestura, Yaz): Females: Oral: Refer to dosing for contraception.

PMDD (Gianvi, Yaz): Females: Oral: Refer to dosing for contraception.

Contraception: Female: Oral: One tablet once daily.

Schedule 1 (Sunday starter): Dose begins on first Sunday after onset of menstruation; if the menstrual period starts on Sunday, take first tablet that very same day. With a Sunday start, an additional method of contraception should be used until after the first 7 days of consecutive administration.

Schedule 2 (Day 1 starter): Dose starts on first day of menstrual cycle taking 1 tablet daily.

Switching from a different contraceptive:

Oral contraceptive: Start on the same day that a new pack of the previous oral contraceptive would have been taken

Transdermal patch, vaginal ring, injection: Start on the day the next dose would have been due

IUD or implant: Start on the day of removal

Use after childbirth (in women who are not breast-feeding) or after second trimester abortion: Therapy may be started ≥4 weeks postpartum. Pregnancy should be ruled out prior to treatment if menstrual periods have not restarted and an additional method of contraception (nonhormonal) should be used until after the first 7 days of consecutive administration.

Missed or late doses (Curtis 2016a):

If one dose is late (<24 hours since dose should have been taken) or if one dose is missed (24 to <48 hours since dose should have been taken): Take dose as soon as possible. Continue remaining doses at the usual time (even if that means 2 doses on the same day).

If ≥2 consecutive doses are missed (≥48 hours since dose should have been taken): Take the most recently missed dose as soon as possible, discard any other missed doses. Continue remaining doses at the usual time (even if that means taking 2 doses on the same day); use back-up contraception until hormonal pills have been taken for 7 consecutive days. If doses were missed during the last week of hormonal (active) tablets (eg, days 15 to 21 of a 28-day pack), omit the hormone-free interval by finishing any remaining hormonal tablets in the current pack and starting a new pack immediately (ie, the day after finishing the hormonal tablets). If unable to start a new pack immediately, back up contraception is needed until hormonal pills from a new pack have been taken for 7 consecutive days. Consider use of emergency contraception in some situations (refer to guidelines for details).

Also refer to prescribing information for product specific information.

Warnings/Precautions

Concerns related to adverse effects:

  • Breast cancer: In women at risk for breast cancer due to family history or susceptibility genes (BRCA1, BRCA2), the use of combination hormonal contraceptives has not been shown to modify the risk for breast cancer. However, breast cancer is a hormonal sensitive tumor and the prognosis for women with a current or recent history of breast cancer may be worse with combination hormonal contraceptive use (Curtis 2016b). Use is contraindicated in women with (or history of) breast cancer.
  • Cervical cancer: The use of combination hormonal contraceptives has been associated with a slight increased risk of cervical cancer; however, studies are not consistent and may be related to additional risk factors (Gierisch 2013). Theoretically, use may affect prognosis of existing disease. Women awaiting treatment for cervical cancer may use combination hormonal contraceptives (Curtis 2016b).
  • Chloasma: Combination hormonal contraceptives, as well as sun exposure and pregnancy, are triggers for chloasma. Women with a susceptibility to chloasma or additional risk factors should avoid exposure to sun or ultraviolet radiation during therapy (Handel 2014).
  • Cholestasis: Risk of cholestasis may be increased with previous cholestatic jaundice of pregnancy or jaundice with prior oral contraceptive use.
  • Hyperkalemia: Drospirenone has antimineralocorticoid activity that may lead to hyperkalemia. Use is contraindicated in patients with conditions that predispose to hyperkalemia (eg renal insufficiency, hepatic dysfunction, adrenal insufficiency); use caution with medications that may increase serum potassium.
  • Lipid effects: Combination hormonal contraceptives may adversely affect lipid levels, including serum triglycerides. Women with hypertriglyceridemia or a family history of hypertriglyceridemia may be at increased risk of pancreatitis when using combination hormonal contraceptives. Consider alternative contraception for women with uncontrolled dyslipidemia.
  • Retinal vascular thrombosis: Discontinue if unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions occur and immediately evaluate for retinal vein thrombosis.
  • Thromboembolic disorders: Discontinue use of combination hormonal contraceptives if an arterial or venous thrombotic event occurs. Oral contraceptives may increase the risk of venous thromboembolism (risk is greatest during first year of use and less than the risk associated with pregnancy); some studies suggest this risk may be higher in preparations with third- or fourth-generation progestins and/or high dose ethinyl estradiol. Women with inherited thrombophilias (eg, protein C or S deficiency, factor V Leiden mutation, prothrombin mutation, antithrombin deficiency) may have increased risk of venous thromboembolism. Age >35 years, hypertension, obesity, and tobacco use also increase the risk of thrombotic events in women taking combination hormonal contraceptives (ASRM 2017; Curtis 2016b; DeSancho 2010; van Vlijmen 2011). Combination hormonal contraceptives may also increase the risk of arterial thrombosis (eg, MI, stroke) and should not be used in women with a history of stroke or ischemic heart disease (Curtis 2016b). Use of combination hormonal contraceptives is contraindicated in women with a high risk of arterial or venous thrombotic disease.
  • Vaginal bleeding: Unscheduled bleeding (breakthrough or intracyclic) and spotting may occur, especially during the first 3 months of therapy. In addition, occasional missed periods may occur. Presentation of irregular, unresolving vaginal bleeding warrants further evaluation including endometrial sampling, if indicated, to rule out malignancy or pregnancy. Amenorrhea or oligomenorrhea may occur after discontinuing combination hormonal contraceptives, especially when such a condition was preexistent.

Disease-related concerns:

  • Bariatric surgery:

- Altered absorption: Consider nonoral contraceptive options in patients who had specific bariatric procedures (Roux-en-Y, biliopancreatic diversion); malabsorptive procedures can potentially decrease absorption of oral contraceptives (Kominiarek 2017; Mechanick 2013; Schlatter 2017). It is difficult to recommend against the use of oral contraceptives in restrictive procedures (sleeve gastrectomy, gastric banding) as the evidence is limited (Merki-Feld 2015).

- Venous thromboembolism risk: Consider discontinuation of estrogen-containing medications 30 days prior to bariatric surgery to reduce risk of venous thromboembolism; however, practice may vary based upon institutional protocols (Mechanick 2013).

  • Cardiovascular disease: Use with caution in patients with risk factors for cardiovascular disease (eg, hypertension, low HDL, high LDL, high triglycerides, older age, diabetes, women who smoke); use of combination hormonal contraceptives may increase the risk of cardiovascular disease (Curtis 2016b). Use of combination hormonal contraceptives may be contraindicated in women at high risk of arterial or venous thrombotic diseases.
  • Depression: Use with caution in patients with depression; discontinue if serious depression recurs.
  • Diabetes: May impair glucose tolerance; use caution in women with diabetes or prediabetes. In general, use of combination oral contraceptives has limited effects on daily insulin needs and no long term effects on diabetes control in women with nonvascular disease. However, use in women with concomitant nephropathy, neuropathy, retinopathy, other vascular disease, or diabetes >20 years duration should be evaluated for contraceptive use based on the severity of the condition (Curtis 2016b). Use is contraindicated in women with diabetes mellitus and vascular disease.
  • Endometrial or ovarian cancer: The risk of endometrial or ovarian cancer is decreased in women using combination hormonal contraceptives (Curtis 2016b; Walker 2015). Oral contraceptives may be used to reduce the risk of ovarian cancer including those women with BRCA1 and BRCA2 mutations (Walker 2015). Women awaiting treatment for endometrial or ovarian cancer may use combination hormonal contraceptives (Curtis 2016b).
  • Gallbladder disease: Combination hormonal contraceptives may cause a small increased risk of gallbladder disease or worsen existing gallbladder disease (Curtis 2016b).
  • Hepatic adenomas: Use of combination hormonal contraceptives is associated with hepatic adenomas (rare); rupture may cause fatal intra-abdominal hemorrhage. Long-term use may be associated with an increased risk of hepatocellular carcinoma (rare). Use of this product is contraindicated in women with hepatic tumors.
  • Hepatic impairment: Combination hormonal contraceptives may be poorly metabolized in women with hepatic impairment. Discontinue if jaundice develops during therapy or if liver function becomes abnormal. Use is contraindicated with preexisting hepatic disease. Use of combination hormonal contraceptives may be considered in women with mild (compensated) cirrhosis but should not be used in women with severe (decompensated) cirrhosis (Curtis 2016b).
  • Hepatitis: Initiation of combination hormonal contraceptives is not recommended in women with acute viral hepatitis or during a flare. Continuation of use in women with chronic hepatitis has not been shown to increase the rate or severity of cirrhotic fibrosis or hepatocellular carcinoma. Continuation of use in women who are carriers has not been shown to trigger liver failure or severe hepatic dysfunction (Curtis 2016b).
  • Hereditary angioedema: Estrogens may induce or exacerbate symptoms in women with hereditary angioedema (Geng 2013; Zuraw 2013).
  • Hypertension: The risk of hypertension may be increased with age, dose, and duration of use. Combination hormonal contraceptives should not be used in women with hypertension and vascular disease, or persistent blood pressure values ≥160 mm Hg systolic or ≥100 mm Hg diastolic. The risks of use may not outweigh the benefits of treatment in women with less severe hypertension (140 to 159 mm Hg systolic or 90 to 99 mm Hg diastolic) or those with hypertension that is adequately controlled (Curtis 2016a). Other risk factors for cardiovascular disease (eg, older age, smoking, diabetes) should be considered when prescribing contraceptives (Curtis 2016b). The manufacturer contraindicates use in women with uncontrolled hypertension and recommends monitoring women with well-controlled hypertension; discontinue therapy if blood pressure rises significantly.
  • Migraine: Evaluate new, recurrent, severe, or persistent headaches. Use of combination hormonal contraceptives may be considered in women who have migraines without aura (including menstrual migraines) (Curtis 2016b). Use in women with headaches with focal neurological symptoms, or migraine headaches with or without aura if >35 years is contraindicated.
  • Solid organ transplant: Although data is limited, serious medical complications have been reported in women with complicated organ transplants (eg, graft failure, rejection, cardiac allograft vasculopathy); use of combination hormonal contraceptives is not recommended in women with complicated organ transplants (Curtis 2016b).
  • Systemic lupus erythematosus (SLE): Women with SLE are at an increased risk for heart disease, stroke, and VTE. Combination hormonal contraceptives should not be used in women with SLE who have positive (or unknown) antiphospholipid antibodies, due to an increased risk of arterial and venous thrombosis (Curtis 2016b).

Concurrent drug therapy issues:

  • Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
  • Thyroid replacement therapy: Estrogens may increase thyroid-binding globulin (TBG) levels leading to increased circulating total thyroid hormone levels. Women on thyroid replacement therapy may require higher doses of thyroid hormone while receiving estrogens.

Special populations:

  • Obese: Available evidence suggests efficacy of combination hormonal contraceptives may be decreased in women with a BMI ≥30 kg/m2, however reductions in effectiveness are considered minimal and information is conflicting. The risk of VTE may be increased in obese women using combination hormonal contraceptives. In general, the benefits of combination hormonal contraceptives may outweigh the risks in obese women who otherwise are eligible for this method (Curtis 2016b).
  • Pediatric: Not for use prior to menarche.
  • Postmenopausal women: Use is not indicated in postmenopausal women.
  • Smokers: [US Boxed Warning]: Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptives use. This risk increases with age, particularly in women >35 years, and with the number of cigarettes smoked. For this reason, combination oral contraceptives should not be used by women who are >35 years of age and smoke. Use is contraindicated in patients >35 years who smoke.
  • Surgical patients: Whenever possible, should be discontinued at least 4 weeks prior to and for 2 weeks following elective surgery associated with an increased risk of thromboembolism or during periods of prolonged immobilization.

Other warnings/precautions:

  • Acne use: For use only in females ≥14 years who have reached menarche, who also desire combination hormonal contraceptive therapy, are unresponsive to topical acne treatments, and have no contraindications to combination hormonal contraceptive use.
  • HIV infection protection: Combination hormonal contraceptives do not protect against HIV infection or other sexually transmitted diseases (Curtis 2016a; Curtis 2016b).
  • Laboratory changes: The use of estrogens and/or progestins may change the results of some laboratory tests (eg, coagulation factors, lipids, glucose tolerance, binding proteins). Drospirenone can also cause an increase in plasma renin activity and plasma aldosterone.
  • Premenstrual dysphoric disorder (PMDD) use: For use only in females who desire combination hormonal contraceptive therapy; use for more than 3 menstrual cycles has not been evaluated. Has not been evaluated for the treatment of premenstrual syndrome.

Monitoring Parameters

Assessment of pregnancy status (prior to therapy); blood pressure (prior to therapy and yearly); weight (optional; BMI at baseline may be helpful to monitor changes during therapy); assess potential health status changes at routine visits (Curtis 2016a). In patients with conditions requiring chronic therapy with medications that may increase potassium, monitor serum potassium during the first treatment cycle. Consider monitoring serum potassium in high risk patients taking strong CYP3A4 inhibitors.

If all doses have been taken on schedule and 1 menstrual period is missed, continue dosing cycle. If 2 consecutive menstrual periods are missed, assess pregnancy status before a new dosing cycle is started.

Monitor patient for vision changes; blood pressure; signs and symptoms of thromboembolic disorders; signs or symptoms of depression; glycemic control in patients with diabetes; lipid profiles in patients being treated for hyperlipidemias. Adequate diagnostic measures, including endometrial sampling, if indicated, should be performed to rule out malignancy in all cases of undiagnosed abnormal vaginal bleeding.

Pregnancy

Pregnancy Considerations

Use is contraindicated in pregnant women. Combination hormonal contraceptives are used to prevent pregnancy; treatment should be discontinued if pregnancy occurs. In general, the use of combination hormonal contraceptives, when inadvertently used early in pregnancy, have not been associated adverse fetal or maternal effects (Curtis 2016b).

The manufacturer states that combination hormonal contraceptives should not be started until ≥4 weeks after delivery in women who choose not to breastfeed, or ≥4 weeks after a second trimester abortion or miscarriage. Due to the increased risk of venous thromboembolism (VTE) postpartum, combination hormonal contraceptives should not be started in any woman <21 days following delivery. The risk decreases to baseline by postpartum day 42. Use of combination hormonal contraceptives in women between 21 and 42 days after delivery should take into consideration the individual woman's risk factors for VTE (eg, age ≥35 years, previous VTE, thrombophilia, immobility, preeclampsia, transfusion at delivery, cesarean delivery, peripartum cardiomyopathy, BMI ≥30 kg/m2, postpartum hemorrhage, or smoking) (Curtis 2016b).
