My son who's 3 and a half has just been given a brown preventer inhaler. I'm a bit worried about the side-effects as he's so young, especially if he's on it a long time as it's a steroid inhaler.. He has had viral wheeze about 5 times now, almost every time he gets a cough or cold, and in the winter he had coughing fits every time he ran and throughout the night that didn't seem always to be related to the viral wheeze. At the moment he doesn't seem to have much breathlessness or coughing, so I'm guessing now that a lot of that was down to the cold weather as I've read that can be a trigger. So with the cold & flu season over and the weather warming up I'm wondering wether there's any point in starting a preventer right now, and wether it's really necessary at all. I'd be grateful for any thoughts or advice.
