My 2yr old has suspected asthma triggered by hayfever and has been on daily cetirizine doses alongside her inhaler. I was advised to stop the cetirizine recently and she started a new inhaler. Since stopping cetirizine and switching from clenil inhaler to flixotide she has been completely hyper! Taking hours to get to sleep and uncharacteristically noisy, fidgety busy. The doctor says it won’t be the inhaler, though I’m not sure. Does anyone have any experience of this please??
