Epinephrine is used to treat wheezing and shortness of breath that commonly occur with asthma. Controlling these symptoms can decrease time lost from work or school. Epinephrine belongs to a class of drugs known as bronchodilators. It works by relaxing the muscles around the airways so that they open up and you can breathe more easily. Use this medication only if you have been told by your doctor that you have asthma.

Read the Patient Information Leaflet for instructions on proper use of this medication and the proper cleaning of the mouthpiece. Consult your doctor or pharmacist if you have any questions.

Shake the canister well before each inhalation. Follow all directions on the product package. If you have any questions, ask your doctor or pharmacist. If you take other asthma drugs by mouth or with inhaling devices, ask your doctor about how to correctly take this medication with your other asthma medicines.

Use this medication exactly as directed in the product package. Inhale by mouth as needed. Take the cap off the mouthpiece. Place the mouthpiece near your mouth and exhale. Place the mouthpiece fully into your mouth and press the inhaler as you breathe in deeply. Hold your breath for as long as comfortable to allow the drug to be absorbed. If more than one inhalation is needed, wait at least 1 full minute between inhalations. Do not use again for at least 4 hours. If your breathing does not get better within 20 minutes after using this medication, or if your breathing gets worse, get medical help right away.

Rinse your mouth after using this medication to help prevent dryness and throat irritation. Do not use more of this medication or use it more often than recommended by the product package or your doctor.
