    • Steroids can slow height growth in kids.
    Upsides and benefits
    • First-choice medication for treating runny and stuffy noses caused by allergies. It works by reducing inflammation in the nose.
    • Because it's used directly where the inflammation is happening, it has fewer side effects than oral steroids do and has a lower chance of causing withdrawal symptoms once the medication is stopped.
    • Can be used as needed to help control symptoms in people age 13 years or older.
    • Available as a generic, which is cheaper.
    • 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.
    Downsides and risks
    • Needs to be primed 10 times before it can be used, or re-primed if not used for more than 2 weeks.
    • Doesn't have a counter on it, so it can be hard to remember how many sprays are left (each bottle has 120 sprays).
    • Since the medicine in Nasonex (Mometasone) is a steroid, it can slow down your healing process if you've hurt your nose or had nose surgery.
    • 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.
