Don't let her struggle too long with her breathing. Its awful being able to breathe in and not out..Get her checked if you are worried. Its always better to be on the safe side.
Also the Asmol is the same as Ventolin..just the cheaper brand and I also use that now. I still get the shakes if I've had too much but its one medication that is very safe and the ONLY medication that can be given to anyone. So keep that in mind. As a person who works with kids we aren't allowed to give panadol out but are allowed to give Ventolin if someone is showing signs of breathing difficulties.
