Summary

What conditions are Fexofenadine and Montelukast used for?
Fexofenadine is used to relieve symptoms of seasonal allergic rhinitis, which is a type of allergy that causes symptoms like a runny nose and itchy eyes, and chronic idiopathic urticaria, which means long-term hives with no known cause. Montelukast is used for the prevention and long-term treatment of asthma, which is a condition that causes wheezing and difficulty breathing, and for the relief of symptoms of seasonal and perennial allergic rhinitis, which are allergies that occur at certain times of the year or all year round.
How do Fexofenadine and Montelukast work in the body?
Fexofenadine works as an antihistamine, which means it blocks histamine receptors in the body. Histamines are chemicals that cause allergy symptoms like sneezing and itching. By blocking these receptors, fexofenadine helps reduce these symptoms. Montelukast works by blocking leukotriene receptors, which are involved in the inflammatory process of asthma and allergic rhinitis. Leukotrienes are substances in the body that cause allergy symptoms, so by blocking them, montelukast helps reduce symptoms like wheezing and nasal congestion.
What are the usual dosages and routes of administration for Fexofenadine and Montelukast?
Fexofenadine is usually taken orally, which means by mouth, with a common adult dose of 180 mg once daily or 60 mg twice daily, depending on the severity of symptoms. Montelukast is also taken orally, with the usual adult daily dose being 10 mg, typically taken in the evening. Both medications should be taken at the same time each day to maintain consistent levels in the body, and fexofenadine should be taken with water, not fruit juices, to ensure proper absorption.
What are the most commonly observed adverse effects of Fexofenadine and Montelukast?
Common side effects of fexofenadine include headache, dizziness, and nausea. Montelukast may cause headache, stomach pain, and tiredness. Both medications share some common side effects like headache and dizziness. However, montelukast has unique warnings related to mental health changes, such as agitation and depression, which are serious side effects that should be reported to a healthcare provider.
What are the important safety warnings and contraindications of Fexofenadine and Montelukast?
Montelukast carries a warning for serious neuropsychiatric events, which means mental health changes like agitation and depression, and should be used with caution in patients with a history of mental health issues. Fexofenadine should not be used by individuals with known hypersensitivity, which means an allergic reaction, to the drug or its components. Both medications should be used cautiously in patients with liver or kidney impairment, and patients should discuss any concerns with their healthcare provider to ensure safe use.

Indications and Purpose

How does combination of Fexofenadine and Montelukast work?

The combination of Fexofenadine and Montelukast works by addressing different aspects of allergic reactions and asthma. Fexofenadine is an antihistamine, which means it helps reduce the effects of histamine, a substance in the body that causes allergy symptoms like sneezing, itching, and runny nose. By blocking histamine, Fexofenadine helps alleviate these symptoms. Montelukast, on the other hand, is a leukotriene receptor antagonist. Leukotrienes are chemicals in the body that contribute to inflammation, especially in the airways, leading to asthma symptoms. Montelukast helps prevent asthma attacks and also reduces symptoms of allergic rhinitis by blocking the action of leukotrienes. Together, these medications provide a more comprehensive approach to managing symptoms of allergies and asthma by targeting both histamine and leukotrienes.
