Pirbuterol

Pirbuterol is used for:

Treating or preventing the symptoms of asthma. It may be used alone or in combination with other medicines. It may also be used for other conditions as determined by your doctor.

Pirbuterol is a beta agonist. It dilates (opens) the bronchioles (air tubes) of the lung by relaxing the smooth muscle around the bronchioles. This helps you by allowing easier airflow into and out of the lungs.

Do NOT use Pirbuterol if:

• you are allergic to any ingredient in Pirbuterol

Contact your doctor or health care provider right away if any of these apply to you.

How to use Pirbuterol :

Use Pirbuterol as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Pirbuterol comes with an additional patient leaflet. Read it carefully and reread it each time you get Pirbuterol refilled.
• Before using Pirbuterol for the first time, spray it into the air twice. This should also be done if you have not used it for 48 hours or more.
• Before using Pirbuterol , be sure that the canister is properly inserted into the inhaler unit and shake well. Exhale slowly and completely. Unless your doctor has told you otherwise, position the mouthpiece between your lips and try to rest your tongue flat. Your doctor may have told you to hold the inhaler 1 or 2 inches (2 or 3 centimeters) away from the open mouth or may have instructed you to use a special spacing device. As you start to take a slow deep breath, press the canister and mouthpiece together at exactly the same time to administer a dose of Pirbuterol . Continue inhaling slowly and deeply and hold for as long as comfortable, then exhale slowly through pursed lips or the nose. If more than 1 inhalation is to be used, wait a few minutes and repeat the above process. Keep the spray away from your eyes.

• Pirbuterol should last for at least 5 hours. Do not increase the dose or use more frequently than recommended without talking to your doctor.
