An Overview of Singulair (Montelukast) – Uses, Side Effects, and Dosage

Overview of Singulair (montelukast)

Singulair, also known by its generic name montelukast, is a medication commonly prescribed to manage symptoms of asthma and allergic rhinitis. This medication is classified as a leukotriene receptor antagonist, which means it helps to block the action of leukotrienes in the body. Leukotrienes are chemicals in the body that contribute to inflammation, constriction of airways, and mucus production, all of which are common features of asthma and allergies.

How Singulair Works

When a person with asthma or allergies is exposed to triggers such as pollen, dust, or pet dander, the immune system releases leukotrienes as part of the inflammatory response. Singulair works by blocking the receptors that leukotrienes bind to, thereby reducing inflammation, relaxing airway muscles, and decreasing mucus production. This helps to alleviate symptoms such as wheezing, shortness of breath, coughing, and nasal congestion.

Indications for Use

Singulair is typically prescribed for the following conditions:

  • Asthma in adults and children as young as 12 months old
  • Seasonal and perennial allergic rhinitis in adults and children as young as 2 years old
  • Exercise-induced bronchoconstriction in individuals aged 6 years and older

Singulair is available in tablet, chewable tablet, and granule form, making it convenient for different age groups to take.

Potential Side Effects

While Singulair is generally well-tolerated, some individuals may experience side effects. Common side effects may include headache, nausea, diarrhea, and stomach pain. In rare cases, Singulair has been associated with neuropsychiatric events such as agitation, aggressive behavior, hallucinations, and suicidal thoughts. It’s essential to monitor for any unusual symptoms and report them to your healthcare provider.

Important Safety Information

Before taking Singulair, it’s crucial to inform your healthcare provider about any existing medical conditions, allergies, or medications you are currently taking. Additionally, it’s essential to follow the prescribed dosage and not exceed it. Singulair is not a rescue medication for acute asthma attacks and should not be used to treat sudden breathing problems.

Clinical Studies

Clinical studies have shown that Singulair is effective in improving lung function, reducing asthma symptoms, and preventing asthma attacks. In a recent study conducted on adults with moderate persistent asthma, those who took Singulair experienced a 28% reduction in asthma exacerbations compared to the control group. The study also demonstrated a 20% improvement in lung function in the Singulair group.

Cost and Availability

The cost of Singulair can vary depending on the dosage, formulation, and insurance coverage. On average, a one-month supply of Singulair tablets can range from $50 to $100. Generic versions of montelukast are also available at a lower cost. Singulair is available by prescription and can be purchased at most pharmacies.
In summary, Singulair (montelukast) is a widely used medication for managing asthma and allergic rhinitis symptoms by blocking the action of leukotrienes in the body. It is essential to follow your healthcare provider’s instructions and monitor for any potential side effects while taking Singulair.
