Most asthma medicines need to reach the lungs to work. There are four devices a person can use to take asthma medicine. Each device delivers just the right dose of medicine.
It’s important to know how to use the asthma medicines the right way. You can ask your nurse, doctor or pharmacist to show you how.
Metered Dose Inhaler
A metered dose inhaler (MDI), also called a pump or puffer, holds medicine in a small can. Each time you press it, the medicine comes out as a fine mist that your child inhales into their lungs.
To work best, an MDI should be used with a spacer. A spacer slows down the mist so more medicine reaches the lungs instead of the mouth or throat. Young kids may need a spacer and a mask to help them inhale the medicine easier.
Dry Powder Inhaler
A dry powder inhaler (DPI) holds powdered medicine. To get the medicine into the lungs, your child must breathe in deep and fast. They should not use a spacer when taking this medicine.
Respimat Soft Mist Inhaler
A soft mist inhaler (SMI) holds water-based medicines in a small can. When you press it, the medicine comes out as a slow mist that looks like a cloud. It doesn’t use extra chemicals to help push the medicine into the lungs and doesn't use a spacer.
Nebulizer
A nebulizer is a machine that turns liquid medicine into a mist. Your child can breathe in the mist through a mask or mouthpiece. Babies, young kids or those with severe asthma who can’t use an inhaler often use a nebulizer.
The medicine helps by:
- Loosening mucus in the lungs so it’s easier to cough out
- Relaxing the airways so your child can breathe more easily
Treatments usually take 15 to 20 minutes.
