      • Available as a generic medication.

      Downsides and risks
      FlonaseClaritin
      • 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.
      • 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).
