Montair LC is a medication that is commonly prescribed for the treatment of asthma and allergic rhinitis. It contains two active ingredients, Montelukast and Levocetirizine, which work together to alleviate symptoms associated with these conditions. In this article, we will delve into the uses, dosage, and side effects of Montair LC to provide a comprehensive understanding of this medication.

Uses of Montair LC

Montair LC is primarily used for two main conditions: asthma and allergic rhinitis. Let’s take a closer look at how this medication can help in managing these health issues.


Asthma is a chronic respiratory condition characterized by inflammation and constriction of the airways, leading to symptoms such as wheezing, shortness of breath, coughing, and chest tightness. Montair LC is prescribed for the long-term management of asthma in adults and children above a certain age.

Montelukast, one of the active ingredients in Montair LC, is a leukotriene receptor antagonist. It works by blocking the action of leukotrienes, which are inflammatory chemicals in the body that play a key role in causing asthma symptoms. By reducing inflammation and preventing airway constriction, Montelukast helps in improving breathing and reducing the frequency and severity of asthma attacks.

Levocetirizine, the other active ingredient, is a second-generation antihistamine that helps in alleviating symptoms like sneezing, runny or itchy nose, and itchy or watery eyes that may be associated with allergic reactions triggering asthma attacks.

Allergic Rhinitis

Allergic rhinitis, also known as hay fever, is an allergic response to allergens such as pollen, dust mites, pet dander, or mold spores. It is characterized by symptoms like sneezing, nasal congestion, runny nose, itching of the nose or throat, and watery eyes. Montair LC is effective in the management of allergic rhinitis by targeting the underlying mechanisms that trigger these symptoms.

Montelukast in Montair LC helps in reducing inflammation in the nasal passages by blocking the action of leukotrienes, which are involved in the allergic response. Levocetirizine complements this action by blocking the release of histamine, a chemical that plays a key role in causing allergic symptoms.

Dosage of Montair LC

The dosage of Montair LC can vary depending on the specific condition being treated, the age of the patient, and their individual response to the medication. It is essential to follow the prescribed dosage and instructions provided by the healthcare provider. Here are some general guidelines on the dosage of Montair LC:

For Asthma

  • Adults: The usual dosage for adults is one Montair LC tablet (containing 10mg of Montelukast and 5mg of Levocetirizine) once daily.
  • Children: The dosage for children is determined based on their age, weight, and severity of asthma symptoms. It is usually prescribed by the pediatrician or healthcare provider.

For Allergic Rhinitis

  • Adults and children above a certain age: The recommended dosage for allergic rhinitis is one Montair LC tablet once daily, usually in the evening.

It is important to take Montair LC regularly as prescribed, even if there is an absence of symptoms. Do not change the dosage or stop taking the medication without consulting your healthcare provider.
