Although no samples have been taken to analyze the concentration in breast milk, a 30 weeks old premature infant who was breastfed for 2-and-a-half months, while his mother was treated with Bosentan and Sildenafil, did not present side-effects. It is approved for Pediatric use from 1-year-old or 10 kg to higher, but there are not published data on neonatal indication.
