Albuterol (also known as salbutamol) is used to treat wheezing and shortness of breath caused by breathing problems (such as asthma, chronic obstructive pulmonary disease). Albuterol 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.

This medication is taken by mouth and does not work right away. It should not be used for sudden attacks of breathing trouble. Your doctor may prescribe a quick-relief inhaler for sudden shortness of breath/asthma attacks while you are on this medication. Always have the quick-relief inhaler with you. Consult your doctor or pharmacist for more details.

Take this medication by mouth as directed by your doctor, usually 3 or 4 times daily. The dosage is based on your medical condition and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. Do not increase your dose or take this drug more often than prescribed because your risk of serious side effects will increase.

Learn which of your medications you should use every day and which you should use if your breathing suddenly worsens. Ask your doctor what to do if you have worsening cough or shortness of breath, wheezing, increased sputum, worsening peak flow meter readings, increased use of your quick-relief inhaler, or if your quick-relief inhaler does not seem to be working well. Learn when you can self-medicate and when you should get medical help right away.

Nervousness, shaking (tremor), headache, or dizziness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
