Levalbuterol (Inhalation)


Levalbuterol is an inhaled medication that is taken as either a solution or as an aerosol powder. Patients inhale the treatment to help prevent or treat bronchospasm that may occur as a result of asthma or other lung diseases.

This medication should only ever be taken as directed by your doctor. You should not ever use more of it than prescribed and should not use it more often then you have been ordered to. Doing so can put you at risk of experiencing more serious side effects and may increase the severity of the side effects. You should also not cease use of this medication without first informing your doctor. If you do so then you may increase your chance of developing breathing problems.

The solution should be used with a jet nebulizer that is connected to a compressor. The nebulizer will come with instructions and information about maintenance. You should follow these instructions carefully and should ask your doctor if there is anything you do not understand. Ensure that you know how to use it before you attempt to do so.

To use the solution in the nebulizer you should follow these steps:

  • Open the pouch containing the vial only when you are ready to use it.
  • Break open the vial and pour the solution into the correct reservoir in the nebulizer.
  • Connect the face mask to the nebulizer and use it to breathe the medication in through the nebulizer.
  • Use the nebulizer for a period of up to five minutes until the full dose of treatment has been consumed.
  • Clean the nebulizer as directed in the instructions after each use and store in a sanitary location.
  • Do not take this medication if the solution is cloudy or contains particulates.
  • Do not mix any other medication or substance into the nebulizer and use it only to take this medication as directed.

To use the inhalation aerosol you should follow these steps:

    • Keep a record of the number of inhalations you are using so you know when to replace your inhaler. An inhaler will usually contain around 200 inhalations and you should update your prescription before you run out of this medication.
    • You should test or prime the inhaler before using it for the first time in a while as it may not deliver the correct dose at first. Prime the canister before taking the dose as directed by your doctor. To do this follow these steps:

O Shake the inhaler thoroughly.
O Remove the cap and inspect for any foreign contaminants.
O Prime the inhaler 4 times pointing the medication away from your face and away from others. You will then receive the correct dose on the 5th use.

  • Shake the inhaler well before use.
  • Breathe out as much as you can to expel all of the air from your body before use.
  • Place inhaler into your mouth and seal with your lips. While breathing in slowly depress the top fully to administer a dose into your lungs.
  • Hold your breath for at least 10 seconds to allow full absorption.
  • If you are to take more than one does then wait for 1 minute between each dose before shaking and repeating.
  • Store the inhaler with the cap on to protect the mouthpiece and keep it clean at all times.
  • Clean the mouthpiece at least once weekly.

To clean the aerosol inhaler weekly you should follow these steps:

  • Remove both the mouthpiece cap and the canister from the inhaler.
  • Was the mouthpiece cap thoroughly in warm water for at least 30 seconds.
  • Wash the inhaler with warm water through both the top and the bottom for at least 30 seconds each.
  • Shake the excess water off and allow the inhaler to dry naturally in the air before reassembling.
  • Do not use anything to clean the canister and ensure that it does not become wet.
  • Make sure the canister is firmly and fully inserted back into the inhaler after cleaning. A blockage will occur more readily if this is not the case.

If the inhaler becomes blocked then you should follow this advice:

  • If medication is not coming out then the inhaler may be blocked. You should begin by following the steps above to clean the inhaler. You should then carry out a test spray to see if this has worked and to clear any remaining water that may still be in the inhaler. You can then take the prescribed dose.
  • Following clearance of a blockage, you should then thoroughly clean the inhaler again and leave it to dry overnight to ensure blockages do not occur again.

You should only ever use this medication as prescribed and should not make any changes to the dosing unless you have been directed to by your doctor. Following the instructions of your doctor will ensure that you are able to get the best benefit from use and will help you to maintain control of your lung condition.
