Contraindications
Pregnancy
Hypersensitivity
Breast Cancer, or another estrogen- or progestin-sensitive cancer
A high risk of arterial or venous thromboembolic disorders
Undiagnosed uterine bleeding
Cautions
Poorly metabolized with hepatic impairment
Use caution in patients with history of migraine, seizure disorder,
Not recommended for women smokers >35 years
Oral contraceptives can reduce production of milk in breastfeeding mothers
Evaluate significant change in headaches and discontinue therapy if indicated
Women taking strong CYP3A4 inducers (for example, carbamazepine, phenytoin, rifampicin, and St. John’s wort) should choose an alternate oral contraceptive due to the possibility of decreased contraceptive efficacy
Discontinue therapy if jaundice occurs

Monitor prediabetic and diabetic women receiving therapy
Consider an alternate contraceptive method for women with uncontrolled dyslipidemia
Evaluate uterine bleeding or amenorrhea
Thromboembolic disease may occur; stop therapy for at least 4 weeks before and through 2 weeks after major surgery; initiate therapy no sooner than 4 weeks after delivery, in women who are not breastfeeding
Safety and efficacy not established for BMI >30 kg/m²
CDC guidelines recommend waiting at least 3 weeks following vaginal birth or 6 weeks after cesarean section to decrease risk for venous thromboembolism before initiating combined hormonal contraceptives; women with additional risk factors for VTE (besides postpartum) should not use combined hormonal contraceptives (MMWR July 7, 2011)
Breast cancer
- 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
- Some studies report a small increase in risk of breast cancer among current or recent users(<6 months since last use) and current users with longer duration of COC use
- A woman's risk depends on conditions where naturally high hormone levels persist for long periods of time including early-onset menstruation before age 12, late-onset menopause, after age 55, first child after age 30, nulliparity
Pregnancy & Lactation
Pregnancy
Extensive epidemiological studies have revealed no increased risk of birth defects in women who have used oral contraceptives prior to pregnancy; studies also do not suggest a teratogenic effect, particularly insofar as cardiac anomalies and limb reduction defects are concerned, when taken inadvertently during early pregnancy
Administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy; oral contraceptives should not be used during pregnancy to treat threatened or habitual abortion
It is recommended that for any patient who has missed two consecutive periods, pregnancy should be ruled out before continuing oral contraceptive use; if the patient has not adhered to prescribed schedule, possibility of pregnancy should be considered at time of first missed period; oral contraceptive use should be discontinued if pregnancy is confirmed
Lactation
Small amounts of oral contraceptive steroids identified in the milk of nursing mothers, and a few adverse effects on child reported, including jaundice and breast enlargement; in addition, oral contraceptives given in postpartum period may interfere with lactation by decreasing quantity and quality of breast milk
If possible, the nursing mother should be advised not to use oral contraceptives but to use other forms of contraception until she has completely weaned her child
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

Adding plans allows you to:
- View the formulary and any restrictions for each plan.
- Manage and view all your plans together – even plans in different states.
- Compare formulary status to other drugs in the same class.
- Access your plan list on any device – mobile or desktop.
