Upsides
  • Qnasl (beclomethasone) treats runny and stuffy nose due to allergies for children ages 4 or older.
  • Since it's used directly where the inflammation is happening, Qnasl (beclomethasone) has fewer side effects than oral steroids and has a lower chance of causing withdrawal symptoms once the medication is stopped.
  • Doesn't make you drowsy or dizzy unlike anti-allergy pills.
  • Has a built-in counter to help keep track of remaining doses.
  • Allegra (fexofenadine) is effective at reducing symptoms for seasonal allergies and chronic hives without significant drowsiness, unlike Benadryl.
  • Approved for kids aged 6 months or older.
  • Allegra (fexofenadine) comes in many forms, like tablet, liquid, and quick-dissolving tablet.
Downsides
  • Need to use daily instead of on an as needed basis for full effects.
  • Only works for nasal symptoms, unlike anti-allergy pills which can help with other allergic symptoms such as watery and itchy eyes.
  • Since Qnasl (beclomethasone) is a steroid, it can slow down your healing process if you've hurt your nose or had nose surgery.
  • Allegra (fexofenadine)'s effectiveness can wear off over time.
  • The dose needs to be adjusted for people with kidney problems.
