Treatment Summary

How Singulair Affects Patients
Montelukast is a drug that blocks the leukotriene receptor in the airways, reducing inflammation and narrowing of the airways to help with asthma and allergies. It takes effect within two hours of being taken, and can be taken with a beta agonist drug for added benefit. Clinical studies have shown that taking doses higher than 10mg per day do not provide any additional benefit. Montelukast has been shown to reduce eosinophils (a type of white blood cell) by 13-15% in people with asthma, and by 13% in those with seasonal allergies.
How Singulair works in the body
Cysteinyl leukotrienes are molecules released by cells like mast cells and eosinophils. When these molecules bind to specific receptors, they can cause symptoms of asthma and allergic rhinitis like bronchoconstriction, mucus production, and inflammation. Montelukast is a drug that binds to these receptors, blocking the molecules from causing these symptoms. This helps relieve asthma and allergic rhinitis.

What does Singulair do for you?
"This drug prevents leukotrienes, which are natural and can cause asthma and allergies, from making breathing difficult by reducing the inflammation in the airways."
Answered by AI
Is Singulair a steroid medication?
"Smith says
You can buy it under its brand name or as a generic. According to Dr. Smith, it blocks certainimmune pathways by preventing the body from making leukotrienes. These are chemicals that contribute to inflammation."
Answered by AI
Why was Singulair taken off the market?
"The U.S. Food and Drug Administration today announced that it is requiring a boxed warning – the agency's most prominent warning – for montelukast (sold under the brand name Singulair and in generic form) to strengthen an existing warning about the risk of neuropsychiatric events associated with the drug. Montelukast is used to treat asthma and seasonal allergies.

Why do they recommend taking Singulair at night?
"Asthma symptoms are often worse at night, so Singulair is typically taken then. It usually starts working after the first dose, but some people don't notice a change for up to a week."
