Singulair Explained: A Complete Overview for Patients and Caregivers

Singulair, the brand name for montelukast sodium, is an oral medication that helps in managing asthma and allergic rhinitis (hay fever). 

It functions by blocking the action of leukotrienes, substances in the body that cause inflammation in the airways, thus reducing symptoms of asthma and allergies. 

Singulair is often prescribed as a long-term treatment for these conditions and is suitable for both children and adults. 

However, it is important to note that Singulair is not designed for the immediate relief of acute asthma attacks.

How Does Singulair Work?

Singulair is primarily used to prevent asthma attacks and manage chronic symptoms in individuals with asthma. 

It is also beneficial in controlling symptoms related to allergic rhinitis such as sneezing, nasal congestion, and itchy nose. 

Additionally, Singulair prevents exercise-induced asthma, making it a valuable medication for those whose asthma is triggered by physical activity. 

Singulair does not contain steroids, making it a preferred option for long-term use.

When to Use Singulair

Singulair is typically prescribed for the following conditions:

• Chronic asthma: Prevents asthma attacks and is used as part of a long-term asthma management plan.
• Exercise-induced asthma: Helps individuals prevent asthma symptoms triggered by physical activity.
• Allergic rhinitis: Treats both seasonal (outdoor) and perennial (indoor) allergic rhinitis symptoms such as runny nose, sneezing, and congestion.

It is important to understand that Singulair is not intended for emergency use during an asthma attack. Individuals should continue using their rescue inhalers as needed for sudden asthma flare-ups.

Who Should Avoid Taking Singulair?

Certain individuals should not take Singulair. It is not suitable for those who are allergic to montelukast sodium or any of the ingredients in the medication. 

Individuals who are sensitive to aspirin or have phenylketonuria should also avoid Singulair, as the chewable tablets contain aspartame, which can be harmful to people with this condition.

Before starting Singulair, consult with a healthcare provider if you have any of the following conditions:

• Liver or kidney problems
• Pregnancy or breastfeeding
• Other medical conditions or allergies

Proper Dosage and Administration of Singulair

Singulair is available in several forms, including chewable tablets and oral granules, and the appropriate form is prescribed based on age and condition:

• Adults and children 12 months and older: Take one dose per day in the evening.
• Exercise-induced asthma: Take Singulair at least two hours before exercise.
• Children: Dosage for children is based on age, with specific recommendations for children aged 2 to 5 years and those 6 to 14 years.

It is essential to follow the prescribed dosing regimen, as taking too much Singulair can lead to complications. If a dose is missed, simply take the next dose at the regular time. Do not double up on doses.

Potential Side Effects of Singulair

Singulair is generally safe for most people, but some may experience side effects. Common side effects include:

In rare cases, more serious side effects may occur, such as:

If any of these serious side effects occur, it is critical to seek medical help immediately. Always inform your doctor about any unusual symptoms or side effects.

Singulair can interact with other medications, which may either reduce its effectiveness or cause harmful side effects. Common interactions include:

• Asthma medications like albuterol
• Steroids such as prednisone
• Antihistamines for allergies, including Zyrtec or Flonase

Before starting Singulair, ensure your healthcare provider knows about all the medications you are taking, including over-the-counter drugs, vitamins, and herbal supplements.
