What is Singulair

Singulair is a leukotriene receptor antagonist that blocks certain substances called leukotrienes.

How Singulair works

Leukotrienes produce narrowing and swelling of the airways in the lungs and can also cause allergy symptoms. By blocking leukotrienes, Singulair improves asthma symptoms, helps control asthma, and improves seasonal allergy symptoms (also known as hay fever or seasonal allergic rhinitis).

When to use Singulair

Your doctor has prescribed Singulair to treat asthma and prevent asthma symptoms during the day and night.

• Singulair is used to treat adults and adolescents aged 15 years and older who are not adequately controlled with their medication and need additional treatment.
• Singulair also helps prevent airway constriction caused by exercise.
• In patients with asthma for whom Singulair is indicated, Singulair may also provide symptomatic relief of seasonal allergic rhinitis.

The dosage of Singulair will depend on your symptoms and the severity of your asthma, as determined by your doctor.

What is asthma?

Asthma is a chronic disease.

Asthma includes:

• Difficulty breathing due to narrowing of the airways. This narrowing of the airways worsens and improves in response to various conditions.
• Overreactive airways that react to many things, such as cigarette smoke, pollen, cold air, or exercise.
• Inflammation of the inner lining of the airways.

Asthma symptoms include: Coughing, wheezing, and congestion in the chest.

What are seasonal allergies?

Seasonal allergies (also known as hay fever or seasonal allergic rhinitis) are an allergic response often caused by airborne pollen from trees, grass, and weeds. Typical symptoms of seasonal allergies may include: Stuffy nose, runny nose, itchy nose; sneezing; watery, swollen, red, and itchy eyes.

Inform your doctor about any allergy or medical condition you have now or have had.

Do not take Singulair

• if you are allergic to montelukast or any of the other components of this medication (listed in section6).

Warnings and precautions

Consult your doctor or pharmacist before starting to takeSingulair.

• If your asthma or breathing worsens, inform your doctor immediately.
• Singulair oral is not indicated for treating acute asthma attacks. If an attack occurs, follow the instructions given by your doctor. Always have your rescue inhaler medication for asthma attacks available.
• It is essential that you or your child use all medications for asthma prescribed by your doctor. Singulair should not replace other asthma medications prescribed by your doctor.
• Any patient being treated with asthma medications should be aware that if they develop a combination of symptoms such as flu-like illness, numbness or tingling of arms or legs, worsening of respiratory symptoms, and/or skin rash, they should consult their doctor.
• Do not take acetylsalicylic acid (aspirin) or anti-inflammatory medications (also known as nonsteroidal anti-inflammatory drugs or NSAIDs) if they worsen your asthma.

Several neuropsychiatric events (e.g., changes in behavior and mood, depression, and suicidal tendencies) have been reported in patients of all ages treated with montelukast (see section4). If you develop these symptoms while taking montelukast, contact your doctor.
