Question 1

How long does it take for Nasonex to work?

Accepted Answer

Nasonex may begin to relieve symptoms within 12 hours of the first dose, but maximum benefit is usually seen within 1-2 days of regular use. For nasal polyps, significant improvement may take 5-6 weeks. Consistency is key—use daily even when symptoms improve.

Question 2

Can I use Nasonex with other allergy medications?

Accepted Answer

Yes, Nasonex can generally be used with oral antihistamines (like cetirizine or loratadine) and decongestants. However, inform your doctor about all medications you're taking, especially other corticosteroids (oral, inhaled, or skin creams) or strong CYP3A4 inhibitors (like ritonavir for HIV).

Question 3

What should I do if I get a nosebleed while using Nasonex?

Accepted Answer

According to NHS guidance, minor nosebleeds are common, especially when treating nasal polyps. Lean forward (not backward), pinch the soft part of your nose for 10 minutes, and breathe through your mouth. If bleeding is frequent, heavy, or lasts more than 20 minutes, contact your doctor.

Question 4

Can children use Nasonex?

Accepted Answer

Yes, Nasonex is approved for children aged 3 years and older for hay fever and perennial allergic rhinitis. The dose is 1 spray in each nostril once daily. Children's height should be monitored during long-term treatment. Nasonex is not approved for nasal polyps in children under 18.

Question 5

Why do I need to prime the bottle?

Accepted Answer

Priming ensures the pump delivers the correct dose. New bottles need 10 pumps until a fine mist appears. If unused for 14+ days, re-prime with 2 pumps. Without proper priming, you may get too much or too little medication.

Question 6

Can I use Nasonex during pregnancy?

Accepted Answer

There is limited data. Use only if clearly needed and under medical supervision. The lowest effective dose should be used for the shortest duration. Discuss with your doctor whether benefits outweigh potential risks. First trimester use should generally be avoided unless essential.

Question 7

How long can I use Nasonex continuously?

Accepted Answer

For allergic rhinitis, Nasonex can be used throughout the pollen season (typically 3-6 months) or year-round for perennial allergies. For nasal polyps, long-term use may be needed. Regular review with your doctor is recommended for use beyond 6 months to assess continued need and monitor for side effects.

Question 8

What's the difference between Nasonex and antihistamine tablets?

Accepted Answer

Antihistamines (like cetirizine) block histamine receptors throughout the body, helping with itching and sneezing. Nasonex is a corticosteroid that reduces inflammation directly in the nasal passages, being more effective for congestion and nasal symptoms. They work differently and are often used together for severe allergies.

Question 9

Can I stop Nasonex abruptly?

Accepted Answer

Yes, for allergic rhinitis treatment lasting less than 2 weeks. If used for longer (especially at high doses for nasal polyps), gradual reduction over 1-2 weeks is recommended to prevent rebound inflammation. Always follow your doctor's instructions for stopping.

Question 10

Why does my nose feel sore after using Nasonex?

Accepted Answer

Mild nasal irritation can occur, often due to the preservative benzalkonium chloride or improper spraying technique (pointing spray toward the nasal septum). Ensure you're directing the spray slightly outward, not upward. If irritation persists, consult your doctor about preservative-free alternatives.

Question 11

Can Nasonex cause weight gain?

Accepted Answer

Systemic absorption is minimal at recommended doses, so weight gain is very unlikely. If you're using high doses long-term (e.g., for nasal polyps) and notice unusual weight gain, moon face, or other systemic steroid effects, consult your doctor for dose adjustment.

Question 12

Is Nasonex addictive?

Accepted Answer

No, Nasonex is not addictive in the traditional sense. However, if stopped abruptly after long-term use, some patients may experience rebound nasal congestion or worsening of underlying inflammation. This is not addiction but rather a need for gradual withdrawal.
