Montelukast

Montelukast is a prescription medication used in the treatment of asthma. It is a medicine in tablet form which helps to prevent and reduce the symptoms of asthma such as difficulty breathing because of narrowed and inflamed airways. This medicine can also help reduce the symptoms of allergies such as allergic rhinitis.

Asthma is a common respiratory condition that can be fatal for some if the symptoms are not managed. Symptoms can include difficulty breathing, wheezing, coughing, and tightness in the chest. Medication is needed to prevent and relieve these symptoms and montelukast is a preventer medicine that is used alongside other preventer and reliever medicines to manage this condition.

How does Montelukast work?

Montelukast is a leukotriene receptor antagonist which is a treatment that is used in conjunction with other treatment methods such as an inhaler. If an inhaler alone is not helping your symptoms, leukotriene receptor antagonists are prescribed.

Leukotrienes are chemicals found naturally in the body which produce an inflammatory response to allergens by narrowing the airways and causing inflammation in the lungs. This causes symptoms of asthma, particularly when the body is exposed to a trigger such as pollen or dust, or exercise.

Montelukast works by blocking these leukotriene chemicals in the lungs to stop the airways narrowing, infamming, and producing excess mucus which all make breathing very difficult.

Who is suitable to take montelukast?

Montelukast is suitable for adults and adolescents over the age of 15 who suffer from symptoms of asthma. This medicine becomes suitable when other asthma treatments are not effectively controlling these symptoms. If you’re currently using a preventer inhaler but your symptoms are still persisting and you’re needing to use your reliever inhaler often, then montelukast is a suitable medicine to be added on to your treatment plan.

This medicine is also suitable for asthma sufferers whose only trigger is exercise. Some people do not experience asthma symptoms until they’re being active, and montelukast has proven to reduce sensitivity of the airways, improve the function of the lungs which makes breathing easier and be active.

Who is not suitable to take montelukast?

There are many factors that might make you unsuitable to take montelukast. Some medications or existing health conditions might mean that you’re unsuitable to use this type of medication. This may be due to interactions between drugs or this medicine may worsen other health conditions.You should always speak to your doctor about any health conditions you may have before taking montelukast to ensure it’s safe for you to take.

Montelukast is a preventer medicine therefore it is not suitable to take if you’re experiencing a sudden attack of breathlessness, you should have other medicines available for when this happens.

Montelukast is also not suitable for children under 15 years of age unless taken at a lower dose in chewable form which has been prescribed by a doctor.

This medicine contains lactose which some people are intolerant to, if so you should speak to a doctor about whether montelukast is suitable for you.

If you have an allergy to montelukast or any other ingredient in this medicine, this treatment is not suitable for you, and you should avoid this medicine to prevent a reaction which could potentially be dangerous.

Montelukast and pregnancy

If you’re pregnant, planning to become pregnant, or are breastfeeding you should also speak to a doctor or pharmacist about the safety of starting a new medication and whether it is suitable for you to take. It’s important to keep your asthma under control during pregnancy, however, it has not been established whether it is safe to take montelukast while pregnant so you should always take your doctor’s advice before taking this medicine. Likewise, if you’re breastfeeding you should speak to your doctor about the safest way to control your asthma.

Montelukast and other medication

Montelukast may be used with other medicines to treat asthma, however, there are some medicines which may not be suitable to take in conjunction with montelukast. You should always check when starting a new medication that it is safe to take with any existing medication that you may be taking to avoid side effects and interaction between the drugs. There are some medicines you should be particularly aware of if you’re taking them with montelukast. You may not be suitable if you’re taking phenobarbital, phenytoin, rifampicin, and gemfibrozil. Discuss with your doctor if you’re taking any of these medicines or any other medication (prescription or non prescription) to ensure that they’re safe to take with montelukast.
