3.6/ 5 average rating with 675 reviewsforNasonex
  • This once-daily, single-pill combination conveniently treats congestion and other allergy symptoms.
  • It doesn't cause any daytime drowsiness unlike other antihistamines.
  • It doesn't require a prescription from your doctor.
  • 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.
  • The decongestant (pseudoephedrine) can make you anxious or your heart race. You may not sleep as well at night.
  • Although you don't need a prescription, you do need to show a photo ID to buy this from behind the pharmacy counter.
  • It may interfere with how your other medicines work. Talk to your doctor or pharmacist before combining with other medicines.
  • 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.
