What is Ventolin HFA?
VENTOLIN HFA is a kind of medicine called a fast-acting bronchodilator. Fast-acting bronchodilators help to quickly open the airways in your lungs so that you can breathe more easily. Each dose of VENTOLIN HFA should last up to 4 to 6 hours. Take VENTOLIN HFA as directed by your doctor. Do not take extra doses or take more often without asking your doctor. Get medical help right away if VENTOLIN HFA no longer helps your symptoms. Also get medical help if your symptoms get worse or if you need to use your inhaler more often. While you are using VENTOLIN HFA, use other inhaled medicines and asthma medicines only as directed by your doctor. Tell your doctor if you are pregnant or nursing, and ask about the use of VENTOLIN HFA. Possible side effects of taking VENTOLIN HFA include fast or irregular heartbeat, chest pain, shakiness, and nervousness. With the first use of a new canister, worsening of wheezing may occur.
