1) WHAT SINGULAIR IS AND WHAT IT IS USED FOR
Singulair is a leukotriene receptor antagonist that blocks substances called leukotrienes. Leukotrienes cause narrowing and swelling of airways in the lungs and 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).
Your doctor has prescribed Singulair to treat asthma, preventing your asthma symptoms during the day and night.
• Singulair is used for the treatment of patients who are not adequately controlled on their medication and need additional therapy.
• Singulair also helps prevent the narrowing of airways triggered by exercise.
• In those asthmatic patients in whom Singulair is indicated in asthma, Singulair can also provide symptomatic relief of seasonal allergic rhinitis.
Your doctor will determine how Singulair should be used depending on the symptoms and severity of your asthma.
What is asthma?
Asthma is a long-term disease.
Asthma includes:
• difficulty breathing because of narrowed airways. This narrowing of airways worsens and improves in response to various conditions.
• sensitive airways that react to many things, such as cigarette smoke, pollen, cold air, or exercise.
• swelling (inflammation) in the lining of the airways.
Symptoms of asthma include: Coughing, wheezing, and chest tightness.
What are seasonal allergies?
Seasonal allergies (also known as hay fever or seasonal allergic rhinitis) are an allergic response often caused by airborne pollens from trees, grasses and weeds. The symptoms of seasonal allergies typically may include: stuffy, runny, itchy nose; sneezing; watery, swollen, red, itchy eyes.
2) BEFORE YOU TAKE SINGULAIR
Take special care with Singulair
• If your asthma or breathing gets worse, tell your doctor immediately.
• Oral Singulair is not meant to treat acute asthma attacks. If an attack occurs, follow the instructions your doctor has given you. Always have your inhaled rescue medicine for asthma attacks with you.
• It is important that you or your child take all asthma medications prescribed by your doctor. Singulair should not be substituted for other asthma medications your doctor has prescribed for you.
• Any patient on anti-asthma medicines should be aware that if you develop a combination of symptoms such as a flu-like illness, pins and needles or numbness of arms or legs, worsening of pulmonary symptoms, and/or rash, you should consult your doctor.
• You should not take acetyl-salicylic acid (aspirin) or anti-inflammatory medicines (also known as non-steroidal anti-inflammatory drugs or NSAIDs) if they make your asthma worse.
