They have small nebulizers on the market now - little portable ones and the medication for these is relatively inexpensive once the cost of the nebulizer itself has been covered. They are also covered by Medicare I believe although I paid for mine.
I use albuterol and advair but I have severe emphysema...and I think I am going to "graduate" to the small nebulizer for delivery next. I love the nebulizers but the larger machine made life inconvenient...the small portable one is going to be a welcome addition to my world.
I also use a nebulizer and I have to haul it everywhere I go and I would have liked the smaller version but my insurance company doesn't want to pay for it. I checked on it a couple of years ago and it was expensive at that time.
