1. What is Montelukast Viatris and what is it used for

Montelukast Viatris contains montelukast, which is a leukotriene receptor antagonist that blocks substances called leukotrienes. Leukotrienes cause narrowing and swelling of the airways in the lungs. By blocking leukotrienes, Montelukast Viatris improves asthma symptoms and helps control asthma.

Your doctor has prescribed Montelukast Viatris for your child to treat asthma and prevent asthma symptoms during the day and night.

• Montelukast Viatris is used for the treatment of patients between 2 and 5 years old who are not adequately controlled with their medication and need additional treatment.
• Montelukast Viatris can also be used as an alternative treatment to inhaled corticosteroids for patients 2-5 years old who have not recently taken oral corticosteroids for asthma and have demonstrated that they are unable to use inhaled corticosteroids.

• Montelukast Viatris also helps prevent narrowing of the airways caused by exercise in patients 2 years of age and older.

Depending on your child's symptoms and the severity of their asthma, your doctor will determine how your child should use Montelukast Viatris.

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.
• The airways are sensitive and react to many things, such as cigarette smoke, pollen, cold air, or exercise.
• Swelling (inflammation) of the inner layer of the airways.

Asthma symptoms include: coughing, wheezing, and chest congestion.

2. What you need to know before your child takes Montelukast Viatris

Tell your doctor about any allergy or medical problem your child has now or has had.

Do not give Montelukast Viatris to your child:

• If they are allergic to montelukast or any of the other ingredients of this medicine (listed in section 6.1).

Warnings and Precautions

• If your child's asthma or breathing gets worse, tell your doctor immediately.
• Montelukast Viatris is not indicated for the treatment of acute asthma attacks. If an attack occurs, follow the instructions your doctor has given your child. Always have your child's rescue inhaler medication for asthma attacks. Talk to your doctor if you or your child needs more rescue inhaler medication than usual for acute asthma attacks.
• It is essential that your child takes all asthma medications prescribed by their doctor. Montelukast Viatris should not replace other asthma medications that the doctor has prescribed for your child.
• If your child is being treated with asthma medications, be aware that if they develop a combination of symptoms such as flu-like illness, tingling or numbness of arms or legs, worsening lung symptoms, and/or skin rash, they should consult their doctor.
• Your child should not take aspirin or non-steroidal anti-inflammatory drugs (also known as non-steroidal anti-inflammatory medications or NSAIDs) if they make their asthma worse.
• Several neuropsychiatric events (such as changes related to behavior and mood, depression, suicide) have been reported in patients of all ages treated with montelukast (see section 4). If your child develops such symptoms while taking montelukast, they should consult their doctor.

Use in Pregnancy

If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before taking this medicine. Your doctor will assess whether you can take montelukast during this period.

This subsection is not applicable to Montelukast Viatris 4 mg, as it is intended for use in children between 2 and 5 years of age. However, the following information is important for the active ingredient, montelukast.

Montelukast is not expected to affect your child's ability to drive a car or operate machinery. However, individual responses to the medication may vary.

Montelukast Viatris Contains Aspartame and Sodium

This medicine contains 2 mg of aspartame in each tablet.

Aspartame is a source of phenylalanine that may be harmful in cases of phenylketonuria (PKU), a rare genetic disorder in which phenylalanine accumulates because the body is unable to eliminate it properly.

This medicine contains less than 1 mmol of sodium (23 mg) per tablet; this is essentially "sodium-free".
