1. What Orilukast is and what it is used for

What Orilukast is
Orilukast is a leukotriene receptor antagonist that blocks substances called leukotrienes.
How Orilukast works
Leukotrienes cause narrowing and swelling of the airways in the lungs. By blocking leukotrienes, Orilukast relieves asthma symptoms and helps control the disease.
When to take Orilukast
Your doctor has prescribed Orilukast for the treatment of asthma in the patient to prevent daytime and nighttime asthma symptoms.

  • Orilukast is used in the treatment of children aged 6 to 14 years whose asthma is not adequately controlled with currently used medications and who require additional therapy.
  • Orilukast may also be used instead of inhaled corticosteroids in patients aged 6 to 14 years who have not recently used inhaled corticosteroids for asthma treatment, or in patients who are unable to use inhaled corticosteroids.
  • Orilukast also helps prevent exercise-induced narrowing of the airways.

Your doctor will determine how to use Orilukast based on the patient's symptoms and severity of asthma.
What is asthma?
Asthma is a chronic disease.
In asthma, the following occur:

  • Breathing difficulties caused by narrowing of the airways. This narrowing worsens and improves in response to various triggers.
  • Airway sensitivity, where airways react to many factors such as cigarette smoke, pollen, cold air, or physical exertion.
  • Swelling (inflammation) of the lining of the airways.

Asthma symptoms include coughing, wheezing, and chest tightness.

2. Important information before taking Orilukast

Tell your doctor if you or your child have ever had any medical conditions or allergies.

When not to take Orilukast

  • Do not take Orilukast if you or your child are allergic to montelukast or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before starting treatment with Orilukast.

  • If your asthma symptoms worsen or you experience breathing difficulties, contact your doctor immediately.
  • Orilukast is not intended for the treatment of acute asthma attacks. If an asthma attack occurs, follow your doctor's instructions. Always keep a reliever medicine available for immediate use during an asthma attack.
  • It is important that you continue taking all anti-asthma medicines prescribed by your doctor. Do not replace other anti-asthma medicines prescribed by your doctor with Orilukast.
  • Consult your doctor if you or your child experience any of the following symptoms while taking anti-asthma medicines: flu-like symptoms, tingling or numbness in the hands or feet, worsening of lung symptoms and/or skin rash.
  • Do not give acetylsalicylic acid (aspirin) or non-steroidal anti-inflammatory drugs (NSAIDs) to the patient if they worsen asthma symptoms.

Various neuropsychiatric events (such as behavioral and mood changes, depression, and suicidal thoughts) have been reported in patients of all ages treated with montelukast (see section 4). If such symptoms occur while taking montelukast, consult your doctor.
