Use in pregnancy: There are no or limited amount of data from the use of ivabradine in pregnant women. Studies in animals have shown reproductive toxicity. These studies have shown embryotoxic and teratogenic effects (see Toxicology under Actions). The potential risk for humans is unknown. Therefore, ivabradine is contraindicated during pregnancy.
Use in lactation: Animal studies indicate that ivabradine is excreted in milk. Therefore, ivabradine is contraindicated during breastfeeding.
