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 is a bronchodilator that works by opening breathing passages to make breathing easier. Use this medication only if you have been told by your doctor that you have asthma.

Clean the mouthpiece after each use as directed in the Patient Information Leaflet. It should also be cleaned at any time that it appears to be clogged or is not working correctly.
Try to keep track of the number of inhalations used from each canister. Discard the canister after you have used the number of inhalations marked on the product package. Do not float the inhaler in water to test if any more drug is left in it.
Headache, nausea, vomiting, nervousness, dizziness, shaking (tremor), trouble sleeping, stomach upset, sweating, dry mouth, bad taste, cough, or sore throat may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
Seek immediate medical attention if any of these rare but very serious side effects occur: chest pain.
