Warnings/Precautions

Concerns related to adverse effects:

• Bleeding irregularities: Use may be associated with amenorrhea, breakthrough bleeding or changes in menstrual flow. Evaluate persistent irregular vaginal bleeding to exclude pregnancy or neoplasm.

• Cholestasis: Use is not recommended in patients with a history of cholestatic jaundice or jaundice associated with pregnancy. Temporarily discontinue if severe generalized pruritus develops. Discontinue of cholestatic jaundice develops.

• Hepatic adenomas or carcinomas: Use of estrogen/progestogen combinations is associated with hepatic adenomas and focal nodular hyperplasia (rare); rupture may cause fatal intra-abdominal hemorrhage. Discontinue use and consider the possibility of a hepatic tumor in the presence of severe upper abdominal pain, liver enlargement, or signs of intra-abdominal hemorrhage.

• Lipid effects: May adversely affect lipid levels, including serum triglycerides. Patients with hypertriglyceridemia may be at increased risk of pancreatitis.

• Thromboembolic disorders: Discontinue use if an arterial or venous thromboembolic event occurs (eg, cerebrovascular accident, deep venous thrombosis, myocardial infarction, pulmonary embolism). The risk of venous thromboembolism with cyproterone/ethinyl estradiol appears to be greater than that of levonorgestrel-containing combined oral contraceptives and similar to that of desogestrel- and drospirenone-containing combined oral contraceptives. Progesterone and/or estrogen should not be taken while on this medication. The increased the risk of venous thromboembolism greatest during first year of use. Patients with activated protein C resistance, hyperhomocysteinemia, protein C or S deficiency, prothrombin mutation, antithrombin III deficiency, or antiphospholipid antibodies (anticardiolipin antibodies, lupus anticoagulant) may have increased risk of venous or arterial thromboembolism, or cerebrovascular accident. Discontinue use if patient is immobilized for an extended period of time (eg, following accident, long-term illness); nonhormonal acne therapy should be used until patient is able to resume regular activities.

Disease-related concerns:

• Breast cancer: Breast cancer is a hormonal sensitive tumor, and the prognosis may be worse with estrogen/progestogen combinations. Use caution when prescribing estrogen/progestin combinations to patients with risk factors for breast cancer or fibrocystic disease of the breast.

• Cardiovascular disease: Use with caution in patients with risk factors for coronary artery disease (eg, hypertension, hypercholesterolemia, morbid obesity, diabetes, increasing age, or cigarette smoking); may lead to increased risk for cardiovascular disease. Patients with androgen-related conditions (severe acne, hirsutism) may have an increased cardiovascular risk. Discontinue use if a significant rise in BP occurs at any time during therapy. Patients with concurrent obesity, hypertension, and diabetes should receive alternative acne therapy.

• Connective tissue disease: Use with caution; may exacerbate connective tissue disease (eg, systemic lupus erythematosus, rheumatoid arthritis, synovitis).

• Depression: Use with caution in patients with depression; consider alternative therapy if depression recurs.

• Diabetes: Use caution in patients with diabetes or prediabetes; monitor closely. Patients with concurrent diabetes, hypertension and obesity should use alternative treatments for acne.

• Diseases exacerbated by fluid retention: Use with caution in patients with diseases which may be exacerbated by fluid retention, including asthma, epilepsy, or cardiac or renal dysfunction.

• Fibroids: Use with caution in patients with fibroids (leiomyomata); discontinue use with sudden enlargement, pain, or tenderness of fibroids.

• Gallbladder disease: May increase the risk of gallbladder disease.

• Hepatic impairment: Discontinue if jaundice, or severe generalized pruritus develops during therapy or if liver function becomes abnormal.

• Hereditary angioedema: Estrogens may induce or exacerbate symptoms in patients with hereditary angioedema. Discontinuation of therapy may be necessary.

• Hypertension: May be used with caution in patients with well controlled hypertension. Monitor BP and discontinue therapy if BP rises significantly. Patients with concurrent diabetes, hypertension and obesity should use alternative treatments for acne.

• Metabolic/Endocrine diseases: Careful evaluation is recommended prior to starting therapy in patients with metabolic or endocrine diseases and when metabolism of calcium and phosphorus is abnormal; monitor regularly as indicated. Patients with concurrent diabetes, hypertension and obesity should use alternative treatments for acne.

• Migraine: Use with caution in patients with a history of migraine. Evaluate new, recurrent, severe, or persistent headaches. Discontinue if severe headache of unknown etiology or worsening of preexisting migraine headaches occur.

• Ocular changes: Use with caution in patients with myopia; progressive astigmatic error, possibly leading to keratoconus, has been observed in some myopic patients receiving estrogen/progesterone. Patients with family history of such disorders may experience rapid advancement of these ocular disorders. Changes in contact lens tolerance or development of visual changes should be evaluated by an ophthalmologist. Discontinue use if loss of vision, papilledema, or ophthalmic vascular lesions occur.

Special populations:

• Body weight: Patients with a combination of diabetes, hypertension and obesity should use alternative treatments for acne.

• Smoking: Cigarette smoking increases the risk of serious cardiovascular events from estrogen/progestin combinations. This risk increases with age, particularly in patients >35 years of age, and with the number of cigarettes smoked. Patients using this combination should not smoke.

• Surgical patients: Whenever possible, drug should be discontinued at least 4 weeks prior to elective surgery; associated with an increased risk of thromboembolism or during periods of prolonged immobilization. Medication should not be restarted until first menstrual period after hospital discharge following surgery.

Reproductive Considerations

Pregnancy should be ruled out prior to treatment.

This product should not be prescribed only for the prevention of pregnancy; however, it will provide reliable contraception if taken as recommended for the approved indications. The risk of venous thromboembolic events may be increased compared to other combination hormonal contraceptives; use of other estrogen/progestogen combination should not be used during treatment with cyproterone/ethinyl estradiol. Patients with uncertain compliance should also use a nonhormonal contraceptive (eg, barrier method) when contraception is needed.

Upon discontinuation of therapy, patients should use a nonhormonal contraceptive to delay pregnancy until at least one normal spontaneous cycle has occurred. Patients with amenorrhea prior to use may remain anovulatory or amenorrheic after discontinuation of therapy.

Additional warnings and precautions associated with combination hormonal contraceptive products should be considered.

Pregnancy Considerations

Feminization of a male fetus is possible. Use is contraindicated in known or suspected pregnancy. Also consider warnings and precautions associated with combination hormonal contraceptive products.

Breastfeeding Considerations

Cyproterone and ethinyl estradiol are present in breast milk.

Based on product labeling, the estimated daily exposure to a breastfed infant is ~0.2% and 0.02% of the daily maternal dose of cyproterone acetate and ethinyl estradiol, respectively. Estrogen/progestogen combinations may reduce milk production. Breastfeeding is not recommended by the manufacturer.

Although this product is not primarily indicated for contraception, additional warnings and precautions associated with combination hormonal contraceptive products should be considered.

Monitoring Parameters

Prior to therapy: Assessment of pregnancy status; BP; physical exam with reference to breasts, liver, extremities, abdomen and pelvic organs; Papanicolaou smear (sexually active patients); urinalysis. Repeat examinations at regular intervals during therapy, including a yearly breast examination.

The first follow-up visit should be 3 months after initiation of treatment. If a menstrual period is missed, the possibility of pregnancy should be considered. Monitor patient for vision changes; BP; 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 should be performed to rule out malignancy in all cases of undiagnosed abnormal vaginal bleeding.

The need for continued treatment should be evaluated periodically; discontinue 3 to 4 cycles after resolution of symptoms.

Evaluate hypothalamic-pituitary function in patients with persistent (≥6 months) amenorrhea (especially associated with breast secretion) following discontinuation of therapy.

Mechanism of Action

Ethinyl estradiol: Estrogens are responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. Estrogens modulate the pituitary secretion of gonadotropins, luteinizing hormone, and follicle-stimulating hormone through a negative feedback system. Estrogen increases levels of sex hormone-binding globulin (SHBG) and may reduce unbound androgen levels. Ethinyl estradiol is a synthetic derivative of estradiol. The addition of the ethinyl group prevents rapid degradation by the liver.

Cyproterone: Steroidal compound with antiandrogenic, antigonadotropic and progestin-like activity.
