Upsides
  • It doesn't cause daytime drowsiness unlike other antihistamines.
  • Side-effects are mild, if any at all.
  • Available over-the-counter without a prescription.
  • It provides quick relief of allergy symptoms for both children and adults.
  • It doesn't interfere with how a lot of other medicines work.
  • 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.
Downsides
  • It's not the best choice if you have persistent, daily allergy symptoms.
  • It's not recommended for children less than 2 years old.
  • 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.
