Pollen grains from trees, grasses and weeds can float through the air in spring, summer or fall. But on their way to fertilize plants and tree flowers, pollen particles often end up in our noses, eyes, ears and mouths. The result can be sneezing spells, watery eyes, congestion and an itchy throat.
The collection of symptoms that affect the nose when you breathe in something you are allergic to is called allergic rhinitis; when the symptoms affect the eyes, it's called allergic conjunctivitis. Allergic...
LABAs should never be used alone in the treatment of asthma in children or adults
when LABAs are needed, they be used for the shortest time possible to achieve asthma control. They are then to be discontinued, if possible, to limit the long-term use
FDA's actions are based on agency analyses of studies showing an increased risk of severe worsening of asthma symptoms, leading to hospitalization in pediatric and adult patients—as well as death in some patients—using the treatment for asthma.
LABAs are available as single ingredient products, or in combination with a corticosteroid medication. (The reason that some LABAs are offered as single-ingredient products is that not all asthma controller medicines are able to be made into a combination product.)
The drugs affected by FDA's announcement include
the single-ingredient products Serevent (generic name: salmeterol) and Foradil (formoterol)
the combination medications Advair (salmeterol and fluticasone) and Symbicort (formoterol and budesonide)
How LABAs Work
LABAs help people with asthma or a lung condition called chronic obstructive pulmonary disease (COPD) breathe easier. They are also used for exercise-induced bronchospasm, which is asthma that is triggered by vigorous physical activity.
Taken through the mouth using an inhaler or a nebulizer, LABAs relax the muscles of the airways to allow more air to flow into and out of the lungs. Their effects last for at least 12 hours.
FDA's recommendations only apply to the use of LABAs in the treatment of asthma.
“Although these medicines play an important role in helping some patients control asthma symptoms, our review of the available clinical trials determined that their use should be limited, whenever possible, due to an increased risk of serious asthma exacerbations and death,” says Badrul Chowdhury, M.D., director of FDA's Division of Pulmonary and Allergy Products.
“The risks of hospitalization and poor outcomes are of particular concern for children," says Dianne Murphy, director of FDA’s Office of Pediatric Therapeutics. "Parents need to know that their child should not be on a LABA alone.”
