Upsides
  • 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.
  • Prevents symptoms and improves lung function in children and adults with chronic asthma.
  • A single 10 mg dose improves exercise-induced asthma symptoms for up to 24 hours.
  • Fewer side effects compared to other asthma treatments.
  • Also relieves nasal allergy symptoms.
  • Effective pill alternative to corticosteroid inhalers.
Downsides
  • 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.
  • You have to use Montelukast every day to control your symptoms.
  • Somewhat less effective than corticosteroid inhalers for asthma.
  • There's no generic available, so it can be expensive.
  • Can cause behavior changes, agitation, aggression, and difficulty sleeping for some people.
