Warnings and precautions

    • Breast cancer

      • Breast cancer is a hormone sensitive tumor. Women with a history of breast cancer or a recent diagnosis may have a worse prognosis if they use combination hormonal contraceptives.
      • Combination hormonal contraceptives have not been proven to reduce breast cancer risk in women who are at high risk due to their family history or susceptibility genes (BRCA1, BRCA2)
      • Women with breast cancer history or who have had it are advised to not use this product.
    • Cervical cancer:

      • Theoretically, it may influence the prognosis for an existing disease.
      • Combination hormonal contraceptives may be used by women who are awaiting treatment for cervical carcinoma.
      • Combination hormonal contraceptives have been linked to a slight increase in cervical cancer risk. However, the evidence is inconsistent and could be due to other risk factors.
    • Chloasma

      • Treatment should be avoided for women who are susceptible to chloasma and other risk factors.
      • Combination hormonal contraceptives as well as sun exposure, pregnancy and sun exposure are all triggers for chloasma.
    • Cholestasis:

      • Contraindicated use of cholestatic jaundice and jaundice during pregnancy
      • Cholesteasis risk may increase if there has been a history of cholestasis in pregnancy, or with previous oral contraceptive use.
    • The Lipid Effects

      • Combination hormonal contraceptives can increase the risk of pancreatitis in women with hypertriglyceridemia and a family history.
      • Women with uncontrolled dyslipidemia should consider alternative contraception.
      • Combination hormonal contraceptives can adversely affect lipid levels, especially serum triglycerides.
    • Retinal vascular embolism:

      • If you experience an undiagnosed loss of vision, papilledema or proptosis, discontinue use immediately and have your retinal veins examined for thrombosis.
    • Thromboembolic disorders

      • The risk of venous embolism may be increased by oral contraceptives (risk is highest in the first year and lowest during pregnancy); some studies have suggested that the risk may be greater for preparations containing third- or fourth-generation progestins, and/or high dose Ethinylestradiol.
      • Women who have inherited thrombophilias, such as protein C or S deficiency and factor V Leiden mutation, antithrombin deficiencies, and prothrombin mutations, may be at greater risk for venous thromboembolism.
      • If you experience an arterial or vein thrombotic event, discontinue using combination hormonal contraceptives.
      • Women who use combined hormonal contraceptives for longer periods of time, such as 35 and older, are more likely to experience thrombotic events.
      • Combination hormonal contraceptives are not recommended for women at high risk of venous or arterial thrombotic diseases.
      • Combination hormonal contraceptives can also increase the risk for arterial thrombosis (eg MI, stroke). Women with a history or ischemic heart disease should not use them.
    • Vaginal bleeding

      • Unresolved vaginal bleeding is a sign of malignancy and pregnancy.
      • Combination hormonal contraceptives may cause amenorrhea and oligomenorrhea, particularly if the condition was not present previously.

      • Patients with high risk factors for cardiovascular disease such as hypertension, high blood pressure, high cholesterol, diabetes, and women who smoke should be cautious. Combination hormonal contraceptives can increase your risk of developing the disease.
      • Women at high risk for arterial or vein thrombotic disease are not advised to use this medication.
    • Depression

      • Patients with a history of depression should be cautious; discontinue use if severe depression recurs.
    • Diabetes:

      • Combination oral contraceptives have a limited effect on insulin requirements and are not long-term effective in controlling diabetes in women who do not have vascular disease.
      • This may impair glucose tolerance. Women with diabetes and prediabetes should be cautious.
      • Contraceptive use should not be used in women who have concomitant retinopathy, neuropathy or nephropathy.
      • Women with diabetes mellitus or vascular disease should not use this medication.
    • Fluid retention can lead to more severe diseases

      • Patients with fluid retention-related diseases should be cautious.

    • Hepatitis

      • Women with chronic hepatitis have not been shown to experience an increase in the severity or rate of cirrhotic fibrisis.
      • It has been proven that continued use of a drug by women who are carriers does not cause liver disease or severe hepatic dysfunction.
      • Combination hormonal contraceptives are not recommended for women suffering from acute viral hepatitis, flares, or other severe conditions.
    • Hereditary angioedema:

      • Women with hereditary angioedema may be affected by estrogens (Geng, 2013; Zuraw 2013, 2013).

      • Combination hormonal contraceptives are not recommended for women who have had multiple organ transplants.
    • Systemic lupus, erythematosus

      • Women with SLE should not use combination hormonal contraceptives if they have antiphospholipid antibodies. This is because there is a greater risk of arterial or venous embolism.
      • Systemic lupus is a condition in which women with SLE are more at risk of heart disease, stroke, or VTE.


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.

If all doses have not been taken on schedule and one menstrual period is missed, the possibility of pregnancy should be considered.

If two consecutive menstrual periods are missed, assess pregnancy status before a new dosing cycle is started.

  • Monitor patient for vision changes;
  • blood pressure;
  • glycemic control in patients with diabetes;
  • signs and symptoms of thromboembolic disorders;
  • signs or symptoms of depression;
  • 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.


How to administer Ethinyl estradiol and norgestrel (Cryselle 28, Elinest)?

Administer at the same time every day.

Combined hormonal contraceptives may be initiated at any time during the menstrual cycle if it is reasonably sure the woman is not pregnant.

Back-up contraception should be used for 7 days a weak unless contraception is initiated within the first 5 days of menstrual bleeding or the woman abstains from sexual intercourse.

Combined hormonal contraceptives may be started immediately following or within the weak of a first or second-trimester abortion; backup contraception is needed for a weak unless contraception is started at the time of the surgical abortion.

According to the manufacturer, if severe diarrhea or vomiting occurs within 3 to 4 hours after taking an active tablet, it should be considered a missed dose; additional contraceptive measures are recommended. Additional guidelines are also available.


Mechanism of action of Ethinyl estradiol and norgestrel (Cryselle 28, Elinest):

Combination hormonal contraceptives can inhibit ovulation through a negative feedback mechanism on hypothalamus. This alters the normal pattern gonadotropin production of a follicle stimulating hormone (FSH), and luteinizing hormone from the anterior pituitary.

FSH in the follicular phase and a midcycle surge with gonadotropins is inhibited. Combination hormonal contraceptives can also cause alterations in the genital system, including cervical mucus changes, which makes it difficult for sperm penetration, even if there is ovulation.

Alterations in the endometrium can also cause unfavorable conditions for nidation.

Combinations of hormonal contraceptives drugs could alter tubal transport of the eggs through the fallopian tubes. The fertility of sperm may also be affected by progestational drugs.
