- Progestins
Description
Ethinyl Estradiol (EE): Reduces luteinizing hormone-releasing hormone release from hypothalamus; reduces gonadotropin release from pituitary; increases synthesis of DNA, RNA, and various proteins in target tissues
Levonorgestrel: Synthetic progestin; ovulation is inhibited from a negative feedback mechanism on hypothalamus, leading to reduced secretion of follicle-stimulating hormone and luteinizing hormone and LH
Other possible mechanisms may include cervical mucus changes that inhibit sperm penetration and endometrial changes that reduce the likelihood of implantation

Warnings
Risk of postpartum VTE decreases after third postpartum week, whereas risk of ovulation increases after third postpartum week; start contraceptive therapy no earlier than 4 weeks after delivery, in women who are not breastfeeding
Acute or chronic disturbances of liver function may necessitate the discontinuation of CHCs use until liver function resolves to normal and CHC causation has been excluded
Hepatic adenomas are associated with CHCs use; studies have shown an increased risk of developing hepatocellular carcinoma in long-term (>8 years) combined oral contraceptive (COC) users (see Contraindications)
Studies suggest a small increased relative risk of developing gallbladder disease among CHC users; use of CHCs may worsen existing gallbladder disease; past history of CHC-related cholestasis predicts an increased risk with subsequent CHC use; women with a history of pregnancy-related cholestasis may be at an increased risk for CHC-related cholestasis
CHCs may decrease glucose tolerance; carefully monitor in prediabetes and diabetes
Consider alternative contraception for women with uncontrolled dyslipidemia
Small proportion of women will have adverse lipid changes while on CHCs; women with hypertriglyceridemia, or a family history thereof, may be at an increased risk of pancreatitis when using CHCs
If new headaches that are recurrent, persistent, or severe develop in women taking the drug, evaluate the cause and discontinue therapy if indicated (see Contraindications)
This product contains FD&C yellow no. 5 (tartrazine), which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons
Carefully observe women with a history of depression, and discontinue therapy if depression recurs to a serious degree
In women with hereditary angioedema, exogenous estrogens may induce or exacerbate symptoms of angioedema
Chloasma may occasionally occur, especially in women with a history of chloasma gravidarum; women with a tendency to chloasma should avoid exposure to the sun or ultraviolet light
Pregnancy and Lactation
Contraindicated in pregnancy because there is no reason to use combined hormonal contraceptives (CHCs) in pregnancy (see Contraindications)
Combined hormonal contraceptives (CHCs) and/or metabolites are present in human milk and in breastfed infants
