Albuterol (also known as salbutamol) is used to treat wheezing and shortness of breath caused by breathing problems (e.g., asthma, chronic obstructive pulmonary disease). Albuterol belongs to a class of drugs known as bronchodilators. It works in the airways by opening breathing passages and relaxing muscles. Controlling symptoms of breathing problems can decrease time lost from work or school.
Take this medication by mouth, usually twice a day (12 hours apart) or as directed by your doctor. Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
Dosage is based on your medical condition and response to treatment. Do not increase your dose or take this drug more often than prescribed because your risk of serious side effects will increase. Adults and children older than 12 years should not take more than 32 milligrams a day. Children aged 6 to 12 years should not take more than 24 milligrams a day.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.
This medication does not work right away and 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 taking this medication. Consult your doctor or pharmacist for more details.
