My 11mo is currently on these breathing treatments for RSV...she isn't eating as much as normal, either, but that is it. My friend's son, who was a ore-teen when he took it for asthema over10years ago said it used to make his heart race. My older daughter took it for Rsv also with no real side-effects I can remember. It seems the aide effects are different depending on the child. We have always had good luck with it,though.
Good luck!
