After a patient suffers from rhinosinusitis, the doctor will recommend the use of anti-inflammatory drugs or antihistamines, which are usually applied locally to the nasal cavity by means of nasal spray, which requires the patient to use the correct nasal spray method, otherwise, even if the correct medication is used, it will not reduce the nasal symptoms. So what is the correct method of nasal spraying? The following is a step-by-step description. 1.Blow out the nose, you can then clean the nasal cavity with physiological seawater. 2.Gently shake the bottle to make the medicine fully mixed, and pull off the cap. 3.Use your right thumb to rest on the bottom of the bottle, index finger and middle finger on each side of the nozzle, clamping the nozzle (see picture). 4, maintain a natural head position (no need to raise your head), use your right hand to put the nozzle of the nasal spray into the left nostril, the direction of the nozzle towards your left eye, that is, towards the outside of the left nasal cavity, keeping the bottle basically vertical, do not overly tilt. As the inner side of the nasal cavity is the nasal septum, so do not spray the nozzle toward the inside of the nasal cavity to avoid spraying on the nasal septum. 5. Gently inhale through the nose while pressing the vial with the right finger to spray 1 spray of the medicine. You can spray 1 more time as prescribed by the doctor. 6.Switch the nasal spray to your left hand and use your left hand to put the nozzle of the nasal spray into the right nostril, with the direction of the nozzle facing your right eye, that is, toward the outside of the right nasal cavity. 7, gently inhale through the nose, while pressing the vial with the left finger, spraying 1 spray of liquid. 8.Wipe the spray tip dry with a paper towel and cap the bottle. After using the nasal spray for a week or more, the nozzle may become clogged and the device should be cleaned as follows, generally every 1 week or so. Open the cap and soak the nozzle in warm water for a few minutes. Some nasal sprays allow you to remove the nozzle and soak it directly in warm water, then rinse it with water, dry it, and put the nozzle back on the bottle. Never poke the nozzle with a needle to prevent damage. For the treatment of rhinitis sinusitis, the formerly commonly used nasal drops are usually no longer chosen, and instead use nasal spray nasal spray, this method allows for uniform distribution of the drug, the dose is easy to control. Nasal sprays are becoming increasingly popular because of their ease of use, fast onset of action, obvious effects, and small side effects, and when used in combination with other medications, they are sure to allow patients to regain smooth breathing and a sense of freshness.
