DYMISTA is for use in your nose only. Do not spray it into your eyes or mouth. If you spray DYMISTA Nasal Spray into your eye(s), flush your eye(s) with large amounts of water for 10 minutes and then call your doctor.

Do not poke or prick the spray pump tip if the spray does not come out. Clean the spray pump tip with warm tap water.

Usual dose:

Adults and Children (6 years of age and older): 1 spray in each nostril twice a day (morning and evening).

Preparing the spray

1. 1. Shake the bottle gently until no residue is observed at the bottom of the bottle and then remove the protective cap (see Figure 1).

Figure 1

1. 2.

   The first time the nasal spray is used, you must prime the pump.

   • Prime the pump by putting two fingers on either side of the spray pump and place your thumb on the bottom of the bottle.
   • Press down and release the pump 6 times into the air away from your face until a fine mist appears (see Figure 2).
   • Now your pump is primed and ready to use.

Figure 2

1. 3. If the nasal spray has not been used for more than 7 days, you will need to prime the pump until a fine mist appears again.

Using the spray

1. 1. Blow your nose to clear your nostrils.

Figure 3

1. 2. Keep your head tilted downwards towards your toes. Do not tilt head backwards.
2. 3. Hold the bottle upright and carefully insert the spray tip into one nostril.
3. 4. Close other nostril with your finger, rapidly press down once on the spray pump and sniff gently at the same time (see Figure 4).
4. 5. Breathe out through your mouth.

Figure 4

1. 6. Repeat in your other nostril.
2. 7. Breathe in gently, and do not tilt your head back after dosing. This will stop the medicine going into your throat and causing an unpleasant taste (see Figure 5).

1. 8. After each use wipe the spray tip with a clean tissue or cloth and then replace the protective cap.

It is important that you take your dose as advised by your doctor. You should use only as much as your doctor recommends.

You may experience a bitter taste in your mouth, especially if you tilt your head backwards when you are using the nasal spray. This is normal. This should go away if you have a soft drink a few minutes after using this medicine. Occasionally you may sneeze a little after using this spray but this soon stops. You may experience an unpleasant smell.
