Upsides and benefits
ClaritinFlonase
  • Relieves allergy symptoms like sneezing and runny nose just as well as other antihistamines, but with less sedation (drowsiness).
  • Also treats hives and itchy skin.
  • Side effects are rare and usually mild.
  • Available over the counter without a prescription.
  • Comes as a tablet, liquid, or quick-dissolving tablet.
  • Can provide quick relief of allergy symptoms for both kids and adults.
  • Okay to take with most other medications because it doesn't have many interactions.
  • 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 and risks
ClaritinFlonase
  • For some people, its effectiveness on treating allergies wears off over time.
  • Some people find that other more sedating antihistamines (like Zyrtec or Benadryl) are more effective for them.
  • If you have daily allergy symptoms, a prescription nasal steroid spray might be better for you long-term.
  • Not for kids under 2 years.
  • The Reditabs version contains aspartame (phenylalanine).
  • 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.
