Montelukast is a generic version of Singulair asthma tablets, manufactured and marketed by the pharmaceutical company Accord. It belongs to a class of asthma medicines called leukotriene receptor antagonist. This means it works by preventing the lungs from reacting to leukotriene, a substance that is naturally released by the human body once the organism is exposed to various triggers that can cause allergic reactions or asthma attacks. As such, it is used to treat hay fever in asthmatics and is also very successful in the management of exercise-induced asthma.

Montelukast in the treatment of asthma

There are numerous benefits when it comes to using montelukast in the treatment of asthma. First of all, montelukast sodium can be used as a complementary treatment, in addition to other asthma medication. Secondly, as opposed to a vast majority of asthma medicines, montelukast is not an inhaler, but is available in a tablet form. Finally, it is a generic and thus more affordable version of the branded Singulair.

Asthma: general background information

As a chronic and usually long-term condition, asthma is much more common than it might seem at the first glance. It affects more than 5 million people within the UK alone. This respiratory condition is marked by inflammation of the airways of the lungs, called bronchi. The inflammation occurs when an individual is exposed to so-called triggers, different outside factors which cause the body’s reaction. Once this happens, muscles around the bronchi contract and the lining of the airways swell.

The usual tell-tale signs of asthma include:

  • Coughing
  • Wheezing
  • Difficulty breathing
  • Tightness of the chest

If there is a continuous worsening of these symptoms after exposure to a trigger or there is an acute asthma exacerbation, this is called an asthma attack. Asthma attacks are especially distressing and when they are particularly severe, they can even become life-threatening and require immediate medical assistance.

What are common asthma triggers?

Asthma triggers come in many different forms and can vary significantly among individuals. The most common ones include:

  • Alcohol
  • Smoke
  • Tobacco smoke (second-hand smoke included)
  • Certain types of food
  • Stress
  • Dust mites
  • Pollen
  • Mould
  • Pet hair
  • Chemicals, fumes and vapours

Aside from these outside factors, asthma attacks can also be brought on by certain natural processes and changes in the body including hormonal changes during puberty, pregnancy or menopause. Likewise, sudden changes in breathing rhythm or temperature, moisture of the air are also considered to be rather common triggers.

Asthma management and Montelukast

Despite its long-term nature and very distressing symptoms, asthma can be successfully managed in a vast majority of cases. With proper medication, some precautions and regular medical check-ups, it is possible to live a perfectly normal life despite your diagnosis. Montelukast is a preventer medicine that can be used in addition to other preventer or reliever treatment in those cases where one type of medicine isn’t enough to successfully manage the condition. By affecting the receptors in the lungs, Montelukast inhibits their reactivity to leukotriene, the substance generated by the immune system when exposed to different triggers. In this way, Montelukast prevents the bronchi from contracting and asthma symptoms from manifesting.

How to use Montelukast (10mg)

As Montelukast is a prescription-only medicine, just like other asthma treatments, even of a different type (such as Ventolin) it is very important to follow the directions provided by the doctor exactly. This way you will be able to minimize the possibility of side effects and allow the treatment to achieve its fullest potential. The most important directions we can provide you here include:

  • Use as prescribed
  • Take one tablet per day (usually in the evening)
  • Take it with or without food
  • Do not stop taking other asthma medicine when starting with Montelukast
  • If you forget a dose, do not take double one next time to compensate – simply take the next tablet at the scheduled time and carry on as normal
  • Montelukast isn’t made to be used as a reliever, meaning it cannot treat an asthma attack in progress – you’ll need your reliever inhaler for this
  • Montelukast is a maintenance treatment used for asthma management so you need to continue using it even when you don’t experience any symptoms
  • In order to stop the treatment, you will need a doctor’s approval
  • If you accidently take more tablets than prescribed, immediately notify your doctor or emergency services
