What should I do if my child needs to use the spacer again if it is still wet after washing? Should I dry it with a clean tea towel?
You should never wipe a spacer dry – wiping the spacer creates static electricity inside the chamber, making the medicine stick to the side walls and not enter the lungs effectively. It is a good idea to always have a spare spacer and not wash both at the same time. Don't wash the spacer during an asthma attack so that it is readily available if needed. If a spacer is wet, do not use it. Use the puffer directly instead while waiting for the spacer to drip dry.
If you use your inhaler the wrong way, less medicine gets to your lungs. A spacer device will help. The spacer connects to the mouthpiece. The inhaled medicine goes into the spacer tube first. Then you take two deep breaths to get the medicine into your lungs. Using a spacer wastes a lot less medicine than spraying the medicine into your mouth.
Spacers come in different shapes and sizes. Ask your provider which spacer is best for you or your child. Almost all children can use a spacer. You do not need a spacer for dry powder inhalers.
The steps below tell you how to take your medicine with a spacer.
Getting Ready
- If you have not used the inhaler in a while, you may need to prime it. See the instructions that came with your inhaler for how to do this.
- Take the cap off the inhaler and spacer.
- Shake the inhaler hard 10 to 15 times before each use.
- Attach the spacer to the inhaler.
- Breathe out gently to empty your lungs. Try to push out as much air as you can.
Breathe in Slowly
- Put the spacer between your teeth and close your lips tightly around it.
- Keep your chin up.
- Start breathing in slowly through your mouth.
- Spray one puff into the spacer by pressing down on the inhaler.
- Keep breathing in slowly. Breathe as deeply as you can.
Hold Your Breath
- Take the spacer out of your mouth.
- Hold your breath as you count to 10, if you can. This lets the medicine reach deep into your lungs.
- Pucker your lips and slowly breathe out through your mouth.
- If you are using inhaled, quick-relief medicine [beta-agonists], wait about 1 to 2 minutes before you take your next puff. You do not need to wait between puffs for other medicines.
- Put the caps back on the inhaler and spacer.
- After using your inhaler, rinse your mouth with water, gargle, and spit. Do not swallow the water. This helps reduce side effects from your medicine.
Keep Your Inhaler Clean
Look at the hole where the medicine sprays out of your inhaler. If you see powder in or around the hole, clean your inhaler. First, remove the metal canister from the L-shaped plastic mouthpiece. Rinse only the mouthpiece and cap in warm water. Let them air-dry overnight. In the morning, put the canister back inside. Put the cap on. Do not rinse any other parts.
Replacing Your Inhaler
Most inhalers come with counters on the canister. Keep an eye on the counter and replace the inhaler before you run out of medicine.
Do not put your canister in water to see if it is empty. This does not work.
Storing Your Inhaler
Store your inhaler at room temperature. It may not work well if it is too cold. The medicine in the canister is under pressure. So make sure not to get it too hot or puncture it.
