This study reviews how a fungal medication called liposomal amphotericin B is used to prevent serious fungal infections in children with weakened immune systems, particularly those with blood cancers or who have had bone marrow transplants. The researchers found that this medicine prevents infections in about 93% of children, though it does cause side effects like low potassium levels in about 23% of patients. However, the study shows that current use of this medicine is quite varied and more high-quality research is needed to determine the best dosing approach.
