I would imagine you can; but remember you will need a Rx to rent one.
A cheaper alternative (and much more convienient to take along) is an inhaler used with a spacer (sometimes called a holding chamber). Brand names are: AeroChamber, OptiChamber, OptiHaler, MicroChamber, Inspirease, and others. The best one we have found -- and we've tried them all -- is the OptiChamber.
We use it with a soft, silicone mask attachment. I recommend the mask even for older kids, it is simpler and they come in different sizes.
Even babies can use spacers, with a mask. You just fit it over their face, spray the inhaler and then hold it in place until they have taken several breaths (usually 6-8). Then repeat, if the Rx directions say to. You can give albuterol and even steroids this way.
Ask your Dr about this option. Then you can have it with you on the plane, in the parks, and wherever. Plus they get their med in seconds, not minutes. That's a big plus for us!
Good luck
