Why Is Montelukast Used for Allergies?More than 50 million Americans have allergic diseases. One of the most common forms of allergies is an allergic reaction to something in the air. Health experts estimate that 35 million Americans have upper respiratory tract symptoms that are allergic reactions to airborne allergens (substances that can cause an allergic reaction). Although allergies can affect many different parts of the body, montelukast is approved only to treat nasal allergies. Symptoms of nasal allergies include:
- Stuffy nose or nasal congestion
- Itchy nose
- Runny nose
Allergy treatment options may include:
- Medicines, such as montelukast
- Allergy shots.
Montelukast is approved to treat both seasonal allergy symptoms and those that last all year long.
How Does Montelukast Work?Montelukast is part of a group of medications called leukotriene modifiers. Leukotrienes are chemicals produced by the body in response to allergens or other problems. In the lungs, they cause swelling and inflammation in the airways and constriction of the muscles of the respiratory tract. In the nose, leukotrienes are released after exposure to allergens, leading to allergy symptoms.
Montelukast works by blocking leukotriene receptors, preventing leukotriene chemicals from causing allergy or asthma symptoms.
