Tablet that prevents asthma symptoms.

Montelukast is an asthma medication that decreases the intensity of asthma symptoms and prevents recurrence by stopping the body from reacting to substances that cause swelling in the lungs.
Our experts can help find the right asthma medication for you. Order Montelukast online and get access to our clinicians, whenever you need them.
Montelukast is a generic medication sold under the brand name Singulair. It’s produced by many different manufacturers, but the active ingredient is the same - Montelukast sodium.
It’s an asthma treatment that’s often prescribed alongside your inhalers or other asthma medications. Montelukast is a preventative treatment that you take once a day, and it helps with exercise induced asthma, wheezing, coughing, and chest tightness.
When stimulated by allergens, our immune system secretes molecules called leukotrienes . These molecules cause swelling and tightening of our airways, and it increases mucus production. This causes problems like allergies and asthma.
Montelukast is a leukotriene receptor antagonist, meaning that it keeps the receptors in your lungs from reacting to leukotrienes. So not only can you experience an improvement in your asthma symptoms, but if you have allergies like hay fever, Montelukast can help relieve unpleasant symptoms.
The Montelukast film-coated tablets are only available as a 10mg dose. If the medication isn’t working for you, we can advise you on an alternative course of treatment since we cannot adjust the dosage of Montelukast we give you.
How we source info.
When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body. Read more in our editorial policy.
Montelukast starts working as soon as you start taking it and reaches peak levels in your system after three hours. The leukotriene levels affecting your lungs will start to reduce immediately, but it can take up to a week for you to get the full benefits this medication can offer.
Forgetting to take medication happens to everyone and you shouldn’t panic if you realise your mistake and too much time has passed. Just skip the dose you missed and resume your routine the following day. If this happens often, you can set an alarm for the same time everyday to help you remember.
If instead of forgetting to take your pill, you took one or two more than you should have, do not worry too much either. It’s difficult to accidentally overdose on Montelukast, so if you take one or two extra pills by mistake, it would likely cause you no harm. But if you feel ill after taking too many pills, you should seek emergency medical attention immediately.
