Patanase Usage

Patanase Nasal Spray

  • Remove the blue plastic overcap.
  • Hold the bottle and press down on the shoulders of the white nasal applicator with your forefinger and middle finger.
  • Support the bottom (base) of the bottle with your thumb while you do this. Prime the bottle five times or until you see a fine mist come out of the nasal spray applicator. After you start using a bottle of Patanase nasal spray, if you do not use it for more than seven days, you will need to prime the pump again two times before use.
  • Gently blow your nose to clear the nostrils. Close one nostril. With your head tipped down (chin toward chest), place the nasal applicator 1/4 to 1/2 inch into a nostril. Hold the medicine bottle upright with the nasal applicator tip aimed toward the cheek side of the nose, away from the center of the nose.
  • Breathe in gently through your nose. While breathing in press firmly and quickly on the applicator to release the spray.
  • Breathe out through your mouth. Do not tip your head back or blow your nose right after using Patanase nasal spray. This may cause you to get a bitter taste in your mouth.
  • Change between the nostrils (alternate). Spray two sprays in each nostril.
  • Wipe the nasal applicator with a clean tissue and replace the blue plastic overcap. 
  • This nasal device should be discarded after the labeled number of sprays (240) or after the expiration date on the medicine label or box.
  • Do not take extra doses or stop taking Patanase spray without talking with your doctor.
