Some people experience shakiness and rapid heartbeat after using albuterol. Fortunately there are various manufacturers and you can try different ones to see if there's one that works better for you than others.
The only one i can take is the levalbuterol thru a nebulizer. I have to limit my intake to 10 puffs to avoid rapid heartbeat, palpations and feeling shaky. I can"t take any of the rescue inhalers without reactions (like a allergic reaction) they make me feel really bad.
