How to Use Nasal Corticosteroid Sprays Correctly: Common Mistakes to Avoid
Nasal corticosteroid sprays, such as Nasonex (mometasone furoate), are a treatment for seasonal allergies, but improper use can reduce effectiveness and cause side effects. Here’s how to use them properly.
Avoid Tilting Your Head Back
Tilting the head backward during application increases the risk of the medication dripping into the throat, reducing its effectiveness and causing a bad taste. Tilt the head slightly forward to ensure the spray remains in the nose. If you feel the taste of the medication in your mouth, you can rinse with water to eliminate as much as possible.
Spray Toward the Outer Nasal Wall

Spraying on the inner wall of the nose can increase the risk of nosebleeds since this wall contains several blood vessels. Direct the spray toward the eye on the same side of the nostril. This will allow the spray to be directed toward the outer nasal wall, which is not as sensitive. Using the right hand for the left nostril and the left hand for the right nostril helps maintain proper orientation.
Do Not Take a Deep Breath
Unlike inhalers for asthma, nasal sprays do not require deep inhalation; their site of action is not the lungs. Deep breathing during application often pushes the medication into the throat, causing problems. Instead, breathe normally through the nose during spraying. If two puffs are needed per nostril, wait 2–3 minutes between doses to allow absorption.
Wait Before Blowing Your Nose
Blowing the nose immediately after application can expel the medication before it is absorbed. Wait 15 minutes before blowing your nose if you feel the need.
Prime the Spray Before First Use
New nasal sprays may not release medication initially. Prime the device by spraying into the air until a fine mist appears. This step should also be repeated if the spray has not been used for a long time.
