Singulair is the brand name for montelukast, an oral prescription drug indicated to prevent asthma attacks. It works by inhibiting the release of leukotrines, chemicals that cause swelling and tightening of the lungs and airway muscles. Singulair does not provide relief from an ongoing asthma attack; it prevents asthma symptoms. According to Drugs.com, it can be used in children as young as 12 months old, but only under a doctor's supervision. Singulair may not be suitable for some people including those allergic to montelukast. There are several alternative treatment options.
Accolate
Accolate is the brand name for zafirlukast, an oral prescription drug that prevents asthma symptoms including wheezing and constriction and swelling of the airways. It is sometimes used to treat allergic rhinitis. Like Singulair, it belongs to the class of drugs known as leukotrine receptor antagonists. A 2003 article published in the "American Journal of Respiratory Medicine" notes that leukotrine agonists including Accolate are usually safe and well tolerated with adverse effect profiles similar to placebo. Common side effects include nausea, flu-like symptoms, rash and fatigue.
Qvar
Qvar is the brand name for beclomethasone dipropionate, an inhaled drug that prevents asthma symptoms. Qvar is a glucocorticoid that works by reducing airway inflammation and is suitable for patients aged 5 years and over. Common side effects include mouth dryness, headache and a stuffy nose. Drugs.com notes that Qvar can reduce the body's ability to fight infection, so it should not be used by people regularly exposed to those who are sick. It may also cause a yeast infection in the mouth. This risk can be reduced by rinsing the mouth with water after use.
Flovent
Flovent is the brand name for fluticasone, an inhaled corticosteroid that prevents chest tightness and wheezing associated with asthma. Flovent is inhaled twice daily in order to prevent an asthma attack. It will not stop an asthma attack that has already started. Flovent may not be suitable for all asthma patients including those with glaucoma, liver disease or tuberculosis. It may also interact with other drugs. Common side effects include oral thrush, a stuffy or runny nose, headache and difficulty speaking.
