Let's take a minute to talk about your medication.  

This is a ProAir HFA inhaler, which contains albuterol. Be sure to shake it well before each use.  

Albuterol treats shortness of breath and wheezing from asthma and other lung conditions. Sometimes it is called a 'rescue inhaler,' because it works quickly and lasts up to 6 hours. You should ask your pharmacist to watch your inhaler technique, to make sure it is correct.  

Albuterol is usually well-tolerated. Still, some side effects could occur, like a rapid heart rate, tremors or nervousness. This is normal and should go away. But, if these or other side effects become reasons you want to stop taking it, please talk with your doctor or pharmacist. 

If you ever feel your breathing is worse, or that you need it more often than usual, you should call your doctor right away. 

The first time you use a new inhaler, it is important to prepare it by shaking and spraying it three times, away from your face. Also, you should clean it once a week--just remove the canister, clean the mouthpiece with warm water, and let it air dry.  

For best results, take albuterol only as prescribed, and follow your doctor's advice about lifestyle changes that may help you breathe better.
