Salbutamol (also known as albuterol) is used to prevent and treat wheezing and shortness of breath caused by breathing problems (such as asthma, chronic obstructive pulmonary disease). It is also used to prevent asthma brought on by exercise. It is a quick-relief medication. Salbutamol 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. Controlling symptoms of breathing problems can decrease time lost from work or school.

Read the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. Follow the illustrated directions for the proper use of this medication and device. For this inhaler to work properly, it is important to keep it dry. If you have any questions, ask your doctor or pharmacist.

This medication is inhaled by mouth as directed by your doctor. Open the inhaler and prepare the dose as directed in the Patient Information Leaflet. Place the mouthpiece near your mouth and breathe out as far as is comfortable. Do not breathe into the inhaler device. Then put the mouthpiece to your lips and breathe in steadily and deeply. Hold your breath for about 10 seconds, or for as long as is comfortable, to allow the drug to be absorbed.

If a child is using this medication, a parent or other responsible adult may need to help the child use the inhaler properly.

If you are using other inhalers at the same time, wait at least 1 minute between the use of each medication.

The dosage is based on your medical condition, age, and response to treatment. If you are using this medication to prevent asthma brought on by exercise, use it 15 minutes before exercise.

Do not increase your dose or use this drug more often than prescribed without your doctor's approval. Using too much of this medication will increase your risk of serious (possibly fatal) side effects.

Keep track of the number of inhalations used from each device. Discard the device after you have used the number of inhalations marked on the manufacturer's package.

Learn which of your inhalers you should use every day (controller drugs) and which you should use if your breathing suddenly worsens (quick-relief drugs). Ask your doctor ahead of time what you should do if you have new or worsening cough or shortness of breath, wheezing, increased sputum, worsening peak flow meter readings, waking up at night with trouble breathing, if you use your quick-relief inhaler more often (more than 2 days a week), or if your quick-relief inhaler does not seem to be working well. Learn when you can treat sudden breathing problems by yourself and when you must get medical help right away.

Tell your doctor if your symptoms do not get better or if they get worse.

Nervousness, dizziness, shaking (tremor), trouble sleeping, headache, nausea, dry/irritated mouth or throat, or unusual taste may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
