Albuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. It is used to treat or prevent bronchospasm in people with asthma and COPD.
A typical metered dose inhaler contains 200 doses. The usual adult dose for bronchospasm is 2 puffs every 4 to 6 hours when needed. Obviously it will depend on how bad your symptoms are as to long your inhaler will last. If your asthma is bad and you need to use the inhaler every day at the maximum amount you can expect one inhaler to last for just over two weeks. Some patients may only need to use half as much and in this case an inhaler will last one month. In patients who have mild asthma may need that one inhaler lasts for three months.
The ProAir HFA inhaler counts down the number of doses on a dose counter on the device. When the dose counter says the number 20, the color of the numbers will change to red. The red numbers are to remind you to refill your prescription or ask your doctor for another prescription. When the dose counter reaches 0, the background color will change to solid red.
