    Upsides and benefits
    • Treats nasal allergy symptoms.
    • Most people don't have many side effects since it works in the nose and doesn't affect the rest of your body.
    • It's a good option for pregnant women. Can also be used for kids 2 years and older.
    • Doesn't make you drowsy or dizzy.
    • No prescription is needed.
    • 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 used regularly for at least a week to see any good effects.
    • Can have an unpleasant smell or taste.
    • Can cause headaches, or burning and stinging in your nose.
    • 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.
    Tips from our pharmacists for people taking the medication
    • Works best when used one week before exposure to allergens. It takes about 1 to 2 weeks until you feel the full effects.
    • Check with your doctor or pharmacist to make sure you know how to use this nose spray. Don't use more than recommended.
    • Shake the spray gently and clear your nose before each use.
    • Before using it for the first time, prime the spray pump until you see a fine mist.
    • Breathe in slowly as you're spraying. Wait a few minutes before blowing your nose if needed.
    • Use daily to control your asthma symptoms.
    • Starts working the same day, but it can take up 1 to 2 weeks to feel the full effects.
    • Pump the inhaler 2 times before inhaling the first dose, or if it's been more than 10 days since your last dose.
    • Wait one minute between doses.
    • Rinse your mouth out with water after each use.
    • Clean the mouthpiece with dry cloth once a week.
