Compare Flonase vs. Nasonex

Flonase (Fluticasone) and Nasonex (Mometasone) are steroids that help relieve allergy symptoms, and are both available as nasal spray. Flonase is a good first-choice medicine for treating a runny or stuffy nose caused by allergies, and it's cheaper than some alternatives. Nasonex is also a good first-choice treatment but can take 1 to 2 weeks to start working fully.

Upsides
  • 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 medication.

Downsides
  • Flonase (Fluticasone) doesn't have a counter on it, so it can be hard to remember how many sprays are left (each bottle has 120 sprays).
  • Needs to be primed (pressed/pumped until a fine spray appears) up to six times prior to using it for the first time, or if you haven't used it in 2 weeks.
  • Since the medicine in Flonase (Fluticasone) is a steroid, it can slow down your healing process if you've hurt your nose or had nose surgery.
  • 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.
