Pregnancy: Regulon is not indicated in pregnancy.
If pregnancy occurs, during treatment with Regulon, further intake should be stopped. However, extensive epidemiological studies have neither showed an increased risk of birth defects in children born to women taking CHCs before pregnancy, nor any teratogenic effect when CHCs were taken inadvertently during early pregnancy.
The increased risk of VTE during the postpartum period should be considered when re-starting Regulon (see Dosage & Administration and Precautions).
Breastfeeding: Lactation may be influenced by CHCs as they may reduce the quantity and change the composition of breast milk. Therefore, the use of CHCs should generally not be recommended until the nursing mother has weaned the child. Small amounts of the contraceptive steroids and/or their metabolites may be excreted with the milk, but there is no evidence that this adversely affects infant health.
