For patients using levalbuterol inhalation aerosol :
- The levalbuterol aerosol canister provides about 200 inhalations, depending on the size of the canister your doctor ordered. You should try to keep a record of the number of inhalations you use so you will know when the canister is almost empty. This canister, unlike some other aerosol canisters, cannot be floated in water to test its fullness.
- When you use the inhaler for the first time, or if you have not used it in a while, the inhaler may not deliver the right amount of medicine with the first puff. Therefore, before using the inhaler, test or prime it.
- To test or prime the inhaler:
- Shake the inhaler well immediately before each use.
- Take the cap off the actuator (or mouthpiece). Inspect the actuator for the presence of foreign objects and make sure that the canister is seated in the actuator before each use.
- Prime the inhaler by releasing 4 test sprays in the air, away from your face. The inhaler will now be ready to provide the right amount of medicine when you use it.
- To use the inhaler:
- Shake the inhaler well
- Breathe out fully through your mouth, expelling as much air from your lungs as possible. Place the mouthpiece fully into your mouth, holding the inhaler in the mouthpiece-down position and closing your lips around it.
- While breathing in deeply and slowly through your mouth, fully depress the top of the metal canister with your middle finger. Immediately after the puff is delivered, release your finger from the canister and remove the inhaler from your mouth.
- Hold your breath for 10 seconds, if possible.
- If your doctor has prescribed more than a single inhalation/puff, wait 1 minute between inhalations. Then, shake the inhaler well and repeat.
- Replace the cap on the mouthpiece after each use
- Clean the actuator or mouthpiece at least once a week.
- To clean the inhaler:
- To clean the blue plastic actuator (or mouthpiece), remove the canister and red mouthpiece cap.
- Wash the actuator through the top and bottom with warm running water for 30 seconds at least once a week
- Shake off the excess water and let the inhaler parts air dry completely before putting the inhaler back together.
- Do not clean the metal canister or allow the metal canister to become wet. Never immerse the metal canister in water.
- To dry, shake off excess water and let the actuator air dry thoroughly, such as overnight.
- When the actuator is dry, replace the canister and the mouthpiece cap. Make sure the canister is fully and firmly inserted into the actuator. Blockage from medicine build-up is more likely to occur if the actuator is not allowed to air dry thoroughly.
If your actuator becomes blocked (little or no medicine coming out of the mouthpiece), wash your actuator and air dry thoroughly. If you need your inhaler before the plastic actuator is completely dry, shake excess water off the actuator, replace canister, shake well, and test spray twice into the air away from your face, to remove most of the water remaining in the actuator. Then take your dose as prescribed. After such use, rewash and air dry the actuator thoroughly.
