For this reason, breath-activated inhalers are sometimes not recommended for younger children. Breath-activated inhalers are not designed for use with a spacer. Dry powder devices contain no propellant. Instead, your asthma medication comes in a dry powder form - inside a small capsule, a disk or a compartment inside your inhaler. The dry powder in some inhalers has no taste, while in others the medication is mixed with lactose which has a sweet taste.
Most people find dry powder devices easy to use, although loading capsules can be fiddly for some.
You also need to take care not to store capsules in a damp place such as the bathroom as this can affect them. They also have a counter indicating the number of doses left. A spacer is a large plastic container, which usually comes in two halves that click together. At one end is a mouthpiece containing a valve and at the other end a hole that fits your aerosol inhaler. Spacers help you to take your asthma medication more effectively.
