Hello everyone) My daughter still has an open oval window in her heart, the cardiologist prescribed Kudesan and Elcar. Not that I don't trust her, but it's risky to give a child all sorts of drops for her. Even on Nurofen she reacts with digestive upset. Of course, these drugs have side effects like vomiting and diarrhea. And the reviews are not unambiguous, especially about Elkar. Maybe someone has experience with these medications and can say something?
