I always find ventolin gives me the shakes

I use Asmol puffer now and thankfully haven't had to use a nebuliser for a long time but I did have to use ventolin earlier this year as that was all that was available and i had the shakes

If the nebuliser or puffer aren't working then I would suggest taking her to the hosp.. I hope she is better soon

ETA: Meant to add. Mine is playing up this week too so I know that even though we are in different states I think this topsy turvy weather is playing havoc with it..
