Good morning! Yes I know the albuterol makes my heart race too but my doctor at Mayo told me to use it before my Tobramycin and it’s helping. It does open up the airways and help me breathe better. It may not be for everyone but it’s a good thing to keep until you know you really can’t. I was ready to give up meds as soon I felt some side effects but recently I listened to a special person in our group and I can say... I’m doing much better! Yesterday I went shopping for 4 long hours! I have not done that in more than a year. I am starting to feel like a normal person again. I hope you feel better! Hugs and prayers! Rita
