The paper by Léauté-Labrèze et al. emphasizes the therapeutic efficacy and the short-term safety of propranolole in the treatment of infantile hemangiomas.  However, recent studies raise concerns regarding the potentially relevant long-term neurodevelopmental or cognitive side-effects of the highly lipophilic propranolol (1).   Indeed, lipophilic beta-blockers cross the blood–brain barrier, leading to sleep and memory disturbance (2).  To give some examples, sleep disturbance, somnolence and irritability have been observed in a significant number of infants treated with the propranolol (3), while it has been shown that such a drug decreases specific memory functions in adults (4).  A recent review suggests that it appears conceivable that blockage of neural pathways critical for learning and memory could be an unrecognized long-term side-effect of propranolol in infants (5).

Further long-term studies are thus needed before to routinely suggest the use of the propranolol in the treatment of infantile hemangiomas.
