Chateal During Pregnancy and Breastfeeding

Chateal is intended to prevent pregnancy. Small amounts of oral contraceptive steroids such as Chateal have been identified in the milk of nursing mothers and a few adverse effects on the child have been reported, including jaundice and breast enlargement. Oral contraceptives given in the postpartum period may interfere with lactation by decreasing the quantity and quality of breast milk. Nursing mothers are advised not to use oral contraceptives and to use other forms of contraception until the child has been completely weaned. Consult your doctor before breastfeeding.
