There are two ways to position the inhaler when using it without a spacer. You can place the inhaler in your mouth. Or you can hold the inhaler 1 in. (2.5 cm) to 2 in. (5.0 cm) in front of your open mouth, without closing your lips over it. This method may be better for getting the medicine into your lungs. But some people may find this too hard to do.
