Inhalers are a type of medication used to treat breathing difficulties caused by asthma and chronic obstructive pulmonary disease (COPD). They administer a mist of medication directly into the lungs, allowing for quick relief of symptoms. Inhalers are an efficient and easy way to treat breathing issues and are an essential tool for those with asthma or COPD.

Inhalers come in two main forms: pressurized-metered dose inhalers (pMDIs) and dry-powder inhalers (DPIs). The type of inhaler your doctor will prescribe will depend on your conditon and other factors such as age, weight, and even the severity of symptoms.

pMDIs contain a propellant to direct the medication into the lungs and are the most commonly used type of inhaler. They require the use of a spacer, a device that helps reduce the aerosol resistance and allows for easier inhalation. DPIs, on the other hand, contain medication that is released without the need for a propellant, allowing for use without a spacer.

It's important to use your inhaler properly in order to get the most from the medication. First, check the expiration date of the inhaler to make sure that it hasn’t expired. Then, if using a pMDI, attach the spacer, which helps the medicine reach the lungs more effectively. Unscrew the cap and shake the inhaler vigorously for a few seconds before use. Then, hold the inhaler upright, with your lips tightly sealed around the mouthpiece and take in a slow and deep breath. As you do, press the canister down and hold while you're inhaling (about 4-5 seconds). When inhaling, try to avoid holding your breath as much as possible and exhale deeply before you administer the next puff.

It's also important to clean the inhaler regularly in order to ensure effective medication delivery and lessened risk of infection. This can be done with a clean cloth and warm, soapy water or a neutral detergent. However, it's important not to immerse the inhaler in water nor use any solvents and oils.

Inhalers are an important and efficient way for those with breathing difficulties to manage their condition. With proper technique and maintenance, you can use your inhaler to its full potential, ensuring the best possible relief from your symptoms.
