Use in Pregnancy: Pregnancy should be ruled out prior to treatment and discontinued if pregnancy occurs. In general, the use of combination hormonal contraceptives when inadvertently taken early in pregnancy have not been associated with teratogenic effects. Due to increased risk of thromboembolism postpartum, combination hormonal contraceptives should not be started earlier than 4-6 weeks following delivery. Hormonal contraceptives may be less effective in obese patients. An increase in oral contraceptive failure was noted in women with a BMI >27.3. Similar findings were noted in patients weighing 90 kg (198 lb) using the contraceptive patch.
Use in Lactation: Estrogen/progestagen-containing oral contraceptives may affect the quality and reduce the quality of milk produced.
A small proportion of the active substances may be excreted in the milk.
