Trembling and increased heart rate are probably the most common and well known of albuterol's side effects. I've had asthma my entire life and have used albuterol for the entire time I've needed treatment and I usually get jittery after using a nebulizer treatment. Part of the reason you're jittery is because nebulizer treatments are more potent and effective than inhalers because it's more medication over a longer period of time in an easily absorbed form. I get sleepy after mine as well, but I agree with everyone else, if the side effects are bothering you a lot you should speak to your doctor.View Thread
