    Upsides and benefits
    cromolynFlovent
    • 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.
    • Available as both an inhaler and Diskus device.
