When Flunisolide Should Not Be Used:
You should not use Flunisolide if you have had an allergic reaction to flunisolide or other corticosteroids such as triamcinolone (Azmacort®) or beclomethasone (Beclovent®). You should not use Flunisolide if you have an untreated nasal infection.

How to Use Flunisolide:

  • Your doctor will tell you how much to use and how often. Do not use more of Flunisolide than your doctor ordered.
  • Before using the nasal spray for the first time, you will need to prime the pump. Remove the white protective cap and put your index and middle finger on the shoulders of the pump. Your thumb goes on the bottom of the bottle. Holding the bottle up and away from your face, push firmly and quickly with your thumb until a fine mist appears. This may take 5 to 6 pushes.
  • If the bottle is not used for 5 days or more, or you have recently cleaned the pump, you may have to prime it again.
  • To use the spray, clear nostrils by gently blowing your nose.
  • Place the spray tip into one nostril (tip should not reach far into the nose), and tilt head forward. Close the other nostril with your finger. Pump one spray into your nose, sniffing gently at the same time. If the doctor wants you to use 2 sprays, pump the spray again.
  • After spraying, remove the tip from your nose and bend your head back for a few seconds.
  • Do the same thing in the other nostril.
  • Wipe the spray tip off with a tissue or soft, clean cloth before replacing the white protective cap.
  • To clean: unscrew pump unit from bottle and soak only the pump unit in warm water. Squirt the pump unit several times while holding it under water. Make sure the pump unit is dry before putting it back together. Prime with 5 or 6 sprays before using again.
  • You need to use Flunisolide on a regular basis. It may take a few days for you to begin to feel better.
  • Never share your medicine with anyone.

If a dose of Flunisolide is missed:

  • Use your medicine as soon as possible unless it is almost time for your next dose.
  • Skip the missed dose if it is almost time for your next regular dose.
  • Do not use two doses at the same time.
