Nasonex (mometasone furoate nasal spray) is a corticosteroid medication commonly used to manage nasal symptoms resulting from seasonal and year-round allergies, or allergic rhinitis. It also treats nasal polyps, which are non-cancerous growths in the nasal passages. Its active ingredient, mometasone furoate, reduces inflammation in the nasal passages, alleviating symptoms like congestion, sneezing, and a runny nose.
Recommended Daily Dosage
The appropriate daily dosage of Nasonex varies based on the condition being treated and the user’s age; each spray delivers 50 micrograms (mcg) of mometasone furoate. For adults and adolescents aged 12 years and older experiencing allergic rhinitis, the recommended starting dose is two sprays in each nostril once daily. Once symptoms are controlled, a reduction to one spray per nostril once daily may be effective for maintenance. If symptoms persist or are not controlled, the dosage can be increased to a maximum of four sprays in each nostril once daily, totaling 400 mcg per day.
Children aged 2 to 11 years with allergic rhinitis are recommended one spray in each nostril once daily, for a total daily dose of 100 mcg. For adults 18 years and older treating nasal polyps, the recommended starting dose is two sprays in each nostril twice daily. Always adhere to the prescribed dosage and do not exceed the maximum daily limits.
Proper Administration and Important Usage Notes
Correct administration ensures Nasonex’s effectiveness. Before first use, or if unused for a week or more, prime the pump by pressing it down until a fine mist appears, requiring about ten actuations initially, or two for repriming after a week of disuse. Gently blowing the nose to clear nasal passages before use can improve medication absorption.
When spraying, tilt your head slightly forward and insert the nozzle into one nostril, pointing it away from the nasal septum and towards the outer corner of the eye. While gently inhaling through the nose, press down on the pump to release the spray. Repeat for the other nostril. After use, wipe the nozzle clean with a tissue and replace the cap to prevent clogging and maintain hygiene.
Nasonex does not provide immediate relief; full therapeutic benefit typically develops after one to two weeks of consistent, daily use. For optimal results, use the medication regularly as prescribed, even when symptoms begin to improve. If a dose is missed, take it as soon as remembered, without exceeding the total daily recommended dosage. Discuss prolonged or significant overuse with a healthcare professional.
When to Consult a Healthcare Professional
Consult a healthcare professional if:
Nasal symptoms do not improve after a week of regular use or worsen, indicating a different underlying condition or need for dosage adjustment.
You experience persistent or severe side effects, such as frequent nosebleeds, sores or white patches in the nose, or changes in vision.
You have pre-existing medical conditions like glaucoma or cataracts, or have recently undergone nasal surgery or experienced nasal injury. Corticosteroids can affect wound healing and may impact certain eye conditions.
You have concerns about long-term use, exposure to infections like chickenpox or measles while using the spray, or signs of systemic corticosteroid effects.
