My 20 month old son was just prescribed Alburterol and a Steroid for RSV, he has a horrible case of RSV that he nearly has pneumonia, weezing and can't take deep breaths. The Albuterol makes him nuts. He is usually this sweet little boy, who listens and barely ever cries. Now he screams, he is jittery to the point it seems like he is on speed. He has gotten violent towards his sisters and me. Today he actually bit me and broke the skin where I couldn't get him off me. For no apparent reason he will scream at the top of his lungs, and he throws himself into things. And sleeping, forget it, this little man has insomnia, within an hour after I get him to bed he is screaming and will not relax. It seems he usually crashes after about 2 hours after his dose, he lays down whereever he is and takes a short nap, about 30 minutes later he gets another jolt of energy and goes nuts. I don't know if maybe 1 1/2 tsp. is too much for him, but its either this or their admitting him to the hospital. Where are my options? :-(
