1. What is Monkasta and what is it used for
What is Monkasta
Monkasta is a leukotriene receptor antagonist that blocks the action of substances called leukotrienes.
How Monkasta works
Leukotrienes cause narrowing and swelling of the airways. By blocking the action of leukotrienes, Monkasta relieves asthma symptoms and helps control asthma.
When to use Monkasta
The doctor has prescribed Monkasta for the treatment of asthma, to prevent asthma symptoms from occurring during the day and at night.
- Monkasta is used to treat children and adolescents aged 6 to 14 years who have not achieved adequate asthma control with their current medications and require additional treatment.
- Monkasta may also be used as an alternative to inhaled corticosteroids in patients aged 6 to 14 years who have not recently taken oral corticosteroids for asthma and are unable to use inhaled corticosteroids.
- Monkasta also helps prevent narrowing of the airways caused by physical exertion.
The doctor will determine how to take Monkasta based on the patient's or child's symptoms and the severity of their asthma.
What is asthma?
Asthma is a chronic disease.
In asthma, the following occur:
- breathing difficulties due to narrowing of the airways, which worsens and improves in response to various factors.
- airway hypersensitivity, which reacts to many factors, such as cigarette smoke, plant pollen, cold air, or physical exertion.
- swelling (inflammation) of the lining of the airways.
Asthma symptoms include: coughing, wheezing, and a feeling of tightness in the chest.
2. Important information before taking Monkasta
Tell your doctor about any health problems or allergies that the patient or child has now or has had in the past.
When not to use Monkasta
- if the patient or child is allergic to montelukast or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Before starting to take or give Monkasta to a child, consult a doctor or pharmacist:
- If the patient's or child's asthma worsens or they experience breathing difficulties, tell your doctor immediately.
- Monkasta taken orally is not intended for the treatment of acute asthma attacks. If an attack occurs, follow the doctor's instructions. Always carry a rescue inhaler with you in case of an asthma attack.
- It is essential to give the patient or child all asthma medications prescribed by the doctor. Do not use Monkasta, 5 mg, chewable tablets as a replacement for other asthma medications prescribed by the doctor.
- Remember to consult a doctor if the patient taking asthma medications experiences a set of symptoms such as flu-like symptoms, tingling or numbness of the hands or feet, worsening of respiratory symptoms, and/or rash.
- Do not give the patient or child aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) if they worsen their asthma symptoms.
Various neuropsychiatric events (such as changes in behavior and mood, depression, and suicidal tendencies) have been reported in patients of all ages treated with montelukast (see section 4). If the patient experiences such symptoms while taking montelukast, consult a doctor.
During treatment with montelukast, consult a doctor if such symptoms occur.
