The Correct Use of Inhalers

Metered dose inhalers, colloquially referred to simply as inhalers, are used to control symptoms of asthma. These inhalers are doctor-prescribed, portable medication that is to be inhaled directly into the lungs. The medication alleviates asthma symptoms, such as shortness of breath, and improve airflow to the lungs. However, inhalers become ineffective if used improperly. If relief isn't felt from taking a dose of an inhaler within half an hour, the dose was likely administered incorrectly. Repeated incorrect use leaves asthma untreated, which can lead to asthma attacks.

Medication Check

• Before the inhaler is used, it should be checked to make sure there is enough medication is in the canister. Some asthmatics can tell how much medicine is left in their inhaler by listening to the sound the inhaler makes upon shaking it, but this may not be the case with everyone. To test for the proper amount of medication, remove the canister from the plastic inhaler casing, then place the canister into a container of water. An empty canister floats on the surface of water, while a full canister sinks. If the canister bobs or tilts up, it is partially full. Take the canister out of the water and put it back into the plastic casing.

Positioning

• Inhalers need to be held in the proper position for them to be used to their maximum effectiveness. The inhaler should be uncapped, then shaken well. The shaking mixes up the medication dose within the canister. After the inhaler is shaken, position it about two inches away from your mouth. The canister needs to be held in an upright position so that the medication comes out properly.

Taking a Dose

• Once the inhaler is in the proper position, tilt your head back and exhale deeply. Then, hold your head upright again and open your mouth as wide as you can. Press down on the canister to release a dose of the medication. At the same time, take a slow, deep breath in. This draws the medication deep into your lungs. Close your mouth and hold your breath for 10 seconds, then exhale and breathe normally.

Repeating Puffs

• In many instances, a doctor prescribes more than one puff on an inhaler per dosing session. If you need to take more than one puff from your inhaler, wait at least one minute in between puffs. By waiting one minute, you allow the medication to reach into your lungs more deeply. With each new puff, you will need to exhale, hold the inhaler away and pump the canister.

Using a Spacer

• A spacer acts as a bridge between the inhaler and your mouth. The spacer attaches to the mouthpiece of the inhaler, with its own mouthpiece at the other end to place in your mouth. These devices can make it easier for some people to receive the medicine, especially younger children. To use a spacer with the inhaler, shake the inhaler to mix up the medication. Then, attach the spacer to the inhaler's mouthpiece and place your mouth on the spacer's mouthpiece. Press the canister to release a medication dose. Hold your breath, then exhale.
