  • Relieves symptoms and improves control of asthma.
  • People report fewer asthma symptoms and better lung function when they take it every day.
  • Inhaling this medicine (rather than taking an oral steroid) gets more into the lungs and less into rest of your body, which lowers the risk of side effects. Inhaled corticosteroids can be used safely for years compared to oral corticosteroids like prednisone.
  • Although not a first-line treatment, Singulair (montelukast) can effectively help children and adults with their asthma and allergies.
  • You only need to take it once a day.
  • Available as chewable tablets or granules that you can mix with food.
  • Singulair (montelukast) has fewer side effects than inhaled medications.
  • You have to use Qvar every day to control your symptoms.
  • You can't lower the dose or stop taking it too suddenly.
  • Steroids can slow height growth in kids.
  • Because steroids suppress your immune system, you can catch bacterial and viral infections easier, and they can take longer to go away.
  • Can cause new or worsening eye pressure, glaucoma, and cataracts.
  • Even as a generic, Singulair (montelukast) is still expensive.
  • May not be a good choice if you have a history of mental conditions.
  • Singulair (montelukast) can't be used as a rescue inhaler if you get an asthma attack.
