If you have nasal or sinus congestion which may be caused by colds, allergies, or sinusitis, you may need to use a nasal spray or sinus irrigation.
Since these devices help introduce fluids into your nose and sinuses, you have to make sure that they are kept clean and sanitary. So here are some tips on the proper use of nasal sprays and sinus irrigation bottles to help keep infections at bay.
1. Always carefully read and follow the instructions provided in the box and product information leaflet. Do not discard these important materials and keep them as handy references. Every device has its own unique prescribed cleaning method.
2. Nasal sprays and sinus irrigation bottles are for personal use only. Always use your own device, and do not share your device with others. Sharing the same device may cause spread of infection.
3. After using a sinunasal irrigation, discard any remaining solution. Never keep remaining solution for later use as bacteria and other microorganisms might grow on them.
4. Thoroughly clean the nasal spray and irrigation bottles after every use.
5. In cleaning nasal sprays, you may use a clean cotton swab to wipe the tip of the nozzle before covering it with the protective cap.
6. Always clean all parts of the irrigation bottle (including the cap and tube) very well using warm water and rinse thoroughly with tap water.
7. After washing, thoroughly dry all parts of the irrigation bottle using a clean paper towel.
8. Reassemble the irrigation bottle and its components and store in a cool dry place until next use
9. In preparing your sinus irrigation for the next use, rinse the bottle and the other parts with cooled preboiled water.
For expert advice, always consult your doctor on the proper use of your nasal spray and sinus irrigation.
