Instructions for use for Nasonex
For use in your nose only.
Read the Patient Instructions for Use carefully before you start to use your Nasonex Nasal Spray. If you have any questions, ask your healthcare provider.
Shake the bottle well before each use.
1. Remove the plastic cap (See Figure 1).
2. Before you use Nasonex for the first time, prime the pump by pressing downward on the shoulders of the white nasal applicator using your index finger and middle finger while holding the base of the bottle with your thumb (See Figure 2). Do Not pierce the nasal applicator. Press down and release the pump 10 times or until a fine spray appears. Do Not spray into eyes. The pump is now ready to use. The pump may be stored unused for up to 1 week without repriming. If unused for more than 1 week, reprime by spraying 2 times or until a fine spray appears.
3. Gently blow your nose to clear the nostrils. Close 1 nostril. Tilt your head forward slightly, keep the bottle upright, carefully insert the nasal applicator into the other nostril (See Figure 3). Do Not spray directly onto the nasal septum (the wall between the two nostrils).
4. For each spray, hold the spray bottle upright and press firmly downward 1 time on the shoulders of the white nasal applicator using your index and middle fingers while supporting the base of the bottle with your thumb. Breathe gently inward through the nostril (See Figure 4).
Note: It is important to keep the Nasonex unit in an upright orientation (as seen in Figure 4). Failure to do so may result in an incomplete or non-existent spray.
5. Then breathe out through the mouth.
6. Repeat in the other nostril.
7. Wipe the nasal applicator with a clean tissue and replace the plastic cap.
Each bottle of Nasonex contains enough medicine for you to spray medicine from the bottle 120 times. Do not use the bottle of Nasonex after 120 sprays. Additional sprays after the 120 sprays may not contain the right amount of medicine, you should keep track of the number of sprays used from each bottle of Nasonex, and throw away the bottle even if it has medicine still left in.
