My ds 4yrs 2months had his first dose of Salbutamol this week. Almost instantly he grabbed his chest in agony and it came and went every couple of minutes for 2 hours. The dr he'd seen before decided on the phone it was probably just his intercostal muscles and wouldn't see him for ages, I was at the surgery about to ring an ambulance as he was in such distress when a doctor came out to see him, he wouldn't let us go home for 2 hours, he was so worried about him. It eventually wore off and was definitely NOT his intercostal muscles hurting as a result of coughing. I found a website saying that Ventolin can cause chest pain though the doctors were sceptical and said they'd never seen it before. Nevertheless, told me never to give it to him again, said it was either the Ventolin itself or the propellent he was allergic to. Anyone else heard of it??
