Pirbuterol Inhalation

Inhaled pirbuterol is used with a special inhaler that comes with patient instructions. Read the directions carefully before using pirbuterol. If you do not understand the directions or you are not sure how to use the inhaler, ask your doctor to show you what to do. Also, ask your doctor to check regularly how you use the inhaler to make sure you are using it properly.

Use pirbuterol only as directed. Do not use more of it and do not use it more often than your doctor ordered. Also, do not stop taking pirbuterol without telling your doctor. To do so may increase the chance of side effects.

Do not stop using pirbuterol or other asthma medicines that your doctor has prescribed for you unless you have discussed this with your doctor.

When you use the inhaler for the first time, or if you have not used it for more than 48 hours, the inhaler may not give the right amount of medicine with the first puff. Therefore, before using the inhaler, prime it by spraying the medicine two times into the air away from the face, and shaking it well before each spray.

Do not use the inhaler for pirbuterol with any other medicine.

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
