Uses

Montelukast is used to control and prevent symptoms caused by asthma (such as wheezing and shortness of breath). It is also used before exercise to prevent breathing problems during exercise (bronchospasm). This medication can help decrease the number of times you need to use your quick relief inhaler.Montelukast is also used to relieve symptoms of hay fever and allergic rhinitis (such as sneezing, stuffy/runny/itchy nose). Since there are other allergy medications that may be safer (see also Warning section), this medication should be used for this condition only when you cannot take other allergy medications or they do not work well.This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden asthma attacks or breathing problems. If an asthma attack or sudden shortness of breath occurs, use your quick-relief inhaler as prescribed.This drug works by blocking certain natural substances (leukotrienes) that may cause or worsen asthma and allergies. It helps make breathing easier by reducing swelling (inflammation) in the airways.

If you are taking this medication to prevent breathing problems during exercise, take your dose at least 2 hours before exercise. Do not take more than one dose in 24 hours. Do not take a dose before exercise if you are already taking this medication daily for asthma or allergies. Doing so may increase the risk of side effects.

Do not increase or decrease your dose or stop using this medication without consulting your doctor. Continue to use this medication regularly to keep your asthma under control, even during sudden asthma attacks or periods when you have no asthma symptoms.

Montelukast Sodium Tablets

How does this medication work? What will it do for me?

Montelukast belongs to a group of medications known as leukotriene receptor antagonists. It is used to prevent and manage asthma symptoms and to relieve the symptoms of seasonal allergies, also known as seasonal allergic rhinitis or hay fever. It may also be used to treat asthma symptoms caused by exercise (exercise-induced bronchoconstriction). It works by blocking the effects of leukotrienes, a substance produced by the body in response to certain “triggers” that cause narrowing and swelling of airways in the lungs. It may be taken alone or in addition to other asthma medications. Montelukast usually starts to work within one day.

When used to prevent and manage asthma, it is important to understand that montelukast should not be used to relieve an asthma attack once it has started. People with asthma should always have their fast-acting asthma relief medication on hand to treat an asthma attack.

Your doctor may have suggested this medication for conditions other than the ones listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

For children 2 to 5 years old, the recommended dose is one chewable 4 mg tablet or one packet of 4 mg granules taken in the evening.

Are there any other precautions or warnings for this medication?

Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take this medication.

Asthma attacks and asthma control: The effectiveness of montelukast in treating acute asthma attacks has not been established. You should not use it to treat an acute asthma attack – have your rescue medication ready in case of an acute attack. Do not stop taking montelukast without consulting your doctor. For this medication to be effective, it is important to take it regularly on a daily basis, even if you feel your asthma is under control, unless otherwise directed by your doctor.

If you feel your asthma symptoms are not improving or are getting worse while taking this medication, contact your doctor. If your asthma is made worse by acetylsalicylic acid (ASA), do not take ASA or other nonsteroidal anti-inflammatory medications (NSAIDS; e.g., ibuprofen, ketoprofen, naproxen). If your asthma is made worse by exercise, continue to use the medications your doctor has prescribed before exercise.

Behaviour changes: Some people have reported changes in behaviour associated with taking montelukast. There have been occasional reports of aggressive behaviour or hostility, anxiousness, disorientation, decreased memory, sleep disturbances, or suicidal thoughts and behaviour. If you experience any of these effects or notice them in a family member who is taking this medication, contact your doctor as soon as possible.

Depression: Montelukast has been associated with mood swings and symptoms of depression. If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.

Phenylketonuria: The chewable tablet form of this medication contains aspartame, an artificial sweetener which contains phenylalanine. The 4 mg chewable tablet contains 0.674 mg of phenylalanine, and the 5 mg chewable tablet contains 0.842 mg. People with phenylketonuria are unable to break phenylalanine down to get rid of it. If you have phenylketonuria, talk to your doctor about other alternatives.

Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. The safety of using montelukast for people with severely reduced liver function has not been established. If you have reduced liver function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: It is not known if montelukast passes into breast milk. If you are breast-feeding and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

stop taking one of the medications,

leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking.
